CAUTION

For the user’s safety, the Powerdrive MD Smart variable speed drive made by the integrator must be connected to a statutory ground (terminal ).If an inadvertent start to the installation presents a risk to the persons or the machines being driven, it is essential to comply with the power connection diagrams recommended in this manual.

The Powerdrive MD Smart variable speed drive is fitted with safety devices which, in the event of a problem, control stopping and thus stop the motor. The motor itself can become jammed for mechanical reasons. Voltage fluctuations, in particular power cuts, may also cause the motor to stop. The removal of the causes of the shutdown can lead to restarting, which may be dangerous for certain machines or installations, in particular those which must comply with Appendix 1 of Decree 92.767 of 29 July 1992 on safety.In such cases, it is essential that the user takes appropriate precautions against the motor restarting after an unscheduled stop.

The Powerdrive MD Smart variable speed drive is designed to be able to supply a motor and the driven machine above its rated speed.If the motor or the machine are not mechanically designed to withstand such speeds, the user may be exposed to serious danger resulting from their mechanical deterioration.Before programming a high speed, it is important that the user checks that the installation can withstand it.

The Powerdrive MD Smart variable speed drive, made from the components described in this manual, is designed to be integrated in an installation or an electrical machine, and can under no circumstances be considered a safety device It is therefore the responsibility of the machine manufacturer, the designer of the installation or the user to take all necessary precautions to ensure that the system complies with current standards, and to provide any devices required to ensure the safety of equipment and personnel.

In the event of non-compliance with the above provisions, Leroy-Somer disclaims any and all liability.This manual describes all the steps required for a system integrator to integrate Powerdrive MD Smart variable speed drive components into an enclosure, as well as its connection and installation. For commissioning and configuring the drive, refer to commissioning guide ref. 5641.

This guide addresses versions of variable speed drives greater than or equal to V5.80

NOTE

Throughout the manual, this symbol warns of consequences which may arise from inappropriate use of the drive, since electrical risks may lead to material or physical damage as well as constituting a fire hazard.

(In accordance with the low voltage directive 2014/35/EU)

1 - General informationThe integrator is responsible for the selection of the components for the variable speed drive. All work related to the installation of the variable speed drive in an enclosure, such as handling, assembly, installation, cabling and testing of the finished product, shall be performed by qualified and authorised personnel. For these basic safety instructions, qualified personnel shall mean competent persons who possess the relevant qualifications.The security instructions described in this document shall be followed carefullyThe variable speed drive produced by the integrator must be tested to ensure its proper functioning, but it must also be certified to the standards of the place of use.Depending on their degree of protection, variable speed drives may contain unprotected live parts, which may be moving or rotating, as well as hot surfaces, during operation.Unjustified removal of protection devices, incorrect use, faulty installation or inappropriate operation could represent a serious risk to personnel and equipmentFor more information, consult the data sheet for each of the components described in this document.

2 - UseVariable speed drives are components designed for integration in electrical installations or machines.They shall comply with standard EN 60204, which stipulates in particular that electrical actuators (which include variable speed drives) cannot be considered as circuit breaking devices and certainly not as isolating switches.Commissioning of variable speed drives can take place only if the requirements of the Electromagnetic Compatibility Directive (EMC 2014/30/CE) are met.The integrator shall ensure the variable speed drives meet the requirements of the Low Voltage Directive 2014/35/CE. The harmonised standards of the DIN VDE 0160 series in connection with standard VDE 0660, part 500 and EN 60146/VDE 0558 are also applicableThe technical characteristics and instructions concerning the connection conditions shall be specified on the nameplate of the variable speed drive and in the documentation provided.

3 - Transportation, storageAll instructions concerning transportation, storage and correct handling must be observed.The climatic conditions specified in the technical manual must be observed.

4 - Installation, cabling The installation and cabling of variable speed drive components in an enclosure shall meet the specifications of the documentation provided.The variable speed drive components must be protected against any excessive stress. In particular, there must be no damage to parts and/or modification of the clearance between components during transportation and handling. Avoid touching the electronic components and contact parts.The variable speed drive components contain parts which are sensitive to electrostatic stresses and may be easily damaged if handled incorrectly. Electrical components must

not be exposed to mechanical damage or destruction (may result in risks to health!).

5 - Electrical connectionWhen work is performed on variable speed drives which are powered up, the national accident prevention regulations must be observed.The electrical installation must comply with the relevant specifications (for example conductor cross-sections, protection via fused circuit-breaker, connection of protective conductor). More detailed information can be found in the documentation.Instructions for an installation which meets the requirements for electromagnetic compatibility, such as screening, earthing, presence of filters and correct insertion of cables and conductors, are given in the documentation supplied with the variable speed drives. These instructions must be followed in all cases, even if the variable speed drive carries the CE mark. Adherence to the limits given in the EMC legislation is the responsibility of the manufacturer of the installation or the machine.

6 - OperationInstallations in which variable speed drives are to be integrated must be fitted with additional protection and monitoring devices as laid down in the current relevant safety regulations, such as the law on technical equipment, accident prevention regulations, etc. Modifications to variable speed drives using control software are permitted.Active parts of the device and the live power connections must not be touched immediately after the variable speed drive is powered down as the capacitors may still be charged. In view of this, warnings must be fixed to the affected areas of the variable speed drive’s enclosure.Permanent magnet motors generate electrical power if they are rotated, even when the supply to the drive is disconnected. In this case, the variable speed drive is powered by the motor terminals. If the load is capable of running the motor, a cut-off device upstream of the motor must be provided to isolate the variable speed drive during maintenance operations.During operation, all doors and protective covers must be kept closed.

7 - Servicing and maintenanceRefer to the manufacturer's documentation.See the Maintenance chapter of this document. This manual is to be given to the end user.

1 - GENERAL INFORMATION1.1 - Working principle of a variable speed driveAn electronic variable speed drive allows an electric motor to be supplied with a variable voltage and frequency by drawing energy from a fixed voltage and frequency electrical network.

Schematic diagram of a variable speed drive:

A variable speed drive essentially consists of:• A filtering element to limit harmonic pollution. - DC Bus reactor or line reactor

• A Passif or Active rectifier:- Passive: connected to a three-phase power supply (the network), it generates continuous voltage. This rectifier is composed of 3

thyristors and 3 diodes (combined bridge rectifier).- Active: connected to a three-phase power supply (the network), it generates continuous voltage. This rectifier is composed of

IGBTs which are driven according to the PWM (Pulse Width Modulation) principle and capacitors which act mainly by "smoothing" the voltage of the DC Bus.

• An inverter that generates the power signal at varying voltages and/or frequencies. This inverter is composed of a DC Bus acting mainly on “smoothing” the output voltage of the rectifier via capacitors and IGBT which are controlled according to the principle of Pulse Width Modulation (PWM).

• Control electronics, i.e. a control module which controls (transmission and reception of signals) the rectifier and the inverter. The power components of the Powerdrive MD Smart variable power drive are available up to 500 kW. Beyond that, the rectifier

and inverter chassis shall be parallelised to achieve the required power levels (> 2.5 MW).

(*) 3 solutions are possible: • a network filtering: - line reactor - low harmonic active filter• filtering on the DC Bus circuit: -continuous reactor

1.2 - Key components of the Powerdrive MD Smart1.2.1 - Filtering elements

Each industrial power supply network has its own intrinsic characteristics (short-circuit capacity, value and voltage fluctuation, phase imbalance, etc.) and supplies equipment, some of which can distort its voltage permanently or temporarily (notches, voltage dips, surge, etc.). Disruptions to the power grid can be caused by the following factors:

• Power factor correction equipment connected near the variable speed drive.

• High power DC variable speed drives that do not have line reactors (or when they are inadequate) connected to the power supply.

• Motor(s) started live and connected to the power supply. When one of these motors is started, the voltage drop exceeds 20%. Such disturbances cause an overcurrent in the input power supply circuit of the drive which can lead to unwanted tripping of the

drive, or in extreme cases to the failure of certain components. The quality of the power supply network therefore has an impact on the performance and reliability of electronic equipment, particularly variable speed drives.

Inductors protect the drive from these different disturbances:

• AC reactor Nidec Leroy-Somer has made the technological choice to install an AC input reactor upstream of the rectifier in order to limit

the disturbances described above. The recommended inductances are outlined in §2.5.1.2. They comply with EN 50178, EN/IEC 61558-2-20, EN/IEC 60076-6.

However, depending on the type of power supply network, Leroy-Somer authorises the use of other filters, see below.

• DC reactor Consult Nidec Leroy-Somer

• Without line reactor On a 12, 18 or 24 PULSE architecture (explanation of the different architectures in §1.3), where the drive has a dedicated

power supply, i.e. it is the only one present downstream of the transformer supplying it, the inductance of the transformer is high enough not to add a line reactor. It will therefore be possible to do without this reactor under certain conditions, see tables below.

1.2.2 - Rectifiers

POWERDRIVE MD Smart rectifiers are elements offered on an IP00 chassis. They generate a DC voltage from the voltage of the three-phase AC power supply network that supplies them. They are AC/DC converters.

The offer includes 2 types of rectifiers:- Passive rectifier: used with basic power supplies (three-phase network), operating in 2 quadrants.

- Active rectifier: used with installations requiring the reinjection of current into the network in the case of driving loads or energy generation (operation in 4 quadrants) or to limit the harmonic rate to a low level (THDI ≤ 3%).

Rectifiers can be used as stand-alone devices to generate a common DC bus for several drives with reduced capacity. This is called a common DC Bus system. This solution is widely used in multi-axis applications such as cranes and travelling gantries or in industrial production lines. In fact, this makes it possible to facilitate energy exchanges between the various axes, thus generating energy savings.

1.2.2.1 - Passive rectifiersThe passive rectifiers of the Powerdrive MD Smart designated MD3REC operate in 2 quadrants, that is, the energy can only flow from the network power supply to the DC Bus (capacitors). In the case of driving loads or load decelerations that are too fast, the energy produced cannot be discharged, DC Bus overvoltage phenomena may occur. To avoid any risk of unwanted tripping, this energy must be dissipated in resistors via a braking module (see chapter §1.2.6).

NoteThe rectifier bridge is composed of switching electronics (thyristors and diode) responsible for the production of harmonics.These elements are not linear elements, the current conduction only takes place for a short time, at each sine wave peak to recharge the DC Bus (capacitors).These harmonics can cause the overheating of transformers, cables, motors, generators and capacitors connected to the same power supply. If the network is too polluted, the lights and displays of the electronic devices start to flicker, circuit breakers may trip, computers malfunction and measuring instruments give erroneous values.

The amplitude of the harmonics is linked to the impedance of the network upstream of the rectifier bridge, and to the structure of the DC Bus downstream of the rectifier bridge The more inductive the mains supply and the motor are, the more these harmonics are reduced. They only have an impact on the quality of the network for capacities installed in frequency converters of a few hundred kVA or in the case where these same capacities are greater than a quarter of the total power installed on a site.

Different drive configurations make it possible to respond to this problem of reinjection of harmonics into the network. Indeed, depending on the choice of the drive architecture and/or adding filters (active or passive), the level of harmonics is reduced. The choice of configuration is related to the required harmonic distortion rate (THD, rate expressed in percentage). The higher the rate, the more the power supply network can be disrupted.

The Nidec Leroy-Somer offer consists of:

Single rectifier chassisThe MD3REC1 single rectifier chassis is a mixed three-phase bridge assembly: 3 thyristors and 3 switching diodes. The 3 thyristors are only used to preload the DC BUS at start-up. After this phase, the rectifier is used as a full voltage diode bridge. Each thyristor or diode connects one of the 3 phases to one of the 2 terminals of the DC bus. The rectifier also incorporates a control card to control the thyristors and make them a standalone DC power supply.

1.2.2.2 - Active rectifiersAn active rectifier allows the energy produced by driving machines or during rapid decelerations to be injected back into the network (4 quadrants of the torque speed plane). They also limit the harmonic content to very low levels (THDI ≤3%).

This rectifier has an identical structure to an IGBT (Insulated Gate Bipolar Transistor) inverter, which is controlled by the MLI Pulse Width Modulation method. It must be associated with a control module. In rectifier mode, it generates a regulated and adjustable continuous voltage from the network power voltage. In order to minimise the disturbance generated by the IGBT control and to guarantee a virtually sinusoidal input current (THDI) <5%), a filtering system must be installed upstream of the rectifier.

Reminder: radio frequency (RFI) signal transmissionVariable speed drive inverters switch high voltages (> 550 V) at high frequencies (several kHz).As a result, they generate radio frequency (R.F.) signals that can disrupt the operation of other devices:• due to the high-frequency leakage currents that "leak" to the earth by the leakage capacity of the variator/motor cable and that of the motor through the metal structures supporting the motor.

• via conduction or re-injection of R.F. signals on the power cable: conducted emissions• by direct radiation in the vicinity of the power supply or variator/motor cable: radiated emissions.

The inverters are adapted to the EMC environments described in IEC/EN 61800-3 category C3. It is possible to add an optional additional filter in the case of a more severe EMC environment.

The main advantages of such a reversible system are:- possible return of energy to the power grid- the input current waveform is slightly distorted, almost sinusoidal- the power factor upstream of the converter is very close to 1- the output voltage for the motor may be higher than that available on the AC power network. Because the voltage of the DC Bus

is regulated at a higher value than that of a passive rectifier, it is possible to obtain a motor voltage of 480 V. In some cases, if the motor allows it, this function allows a lower motor current to be obtained and consequently the design of the output inverter to be optimised.

Absorbed line current, MDRTHDI (*) <5%

The active rectifier is incorporated into an MD3INV inverter chassis.Since the DC output of an active rectifier consists of a high value of capacitors, it is imperative, when powering on, to gradually raise the voltage of the DC bus before unlocking the rectifier. This preload operation is possible with the MD3PRG module (for details, see §1.2.3).

For normal conditions of use, the active rectifier shall incorporate:- Filtering: an RFI filter, a Regen reactor and a LC sine filter, - an MD3INV inverter,- an MD3PRG preload module.

Beyond 500 kW, the MD3INV chassis can be combined in parallel up to 5 per output, allowing a power output of 2.5 MW. In this case, it is necessary to add a parallelisation module. For more details, refer to §1.2.5.

1.2.3 - Preload module

The MD3PRG preload module allows the DC bus to be powered up gradually from an active rectifier system or from a DC bus system. It allows, through controlled thyristors, the voltage of the DC BUS to be increased gradually.From a certain VDC voltage threshold, information is sent to the control module which also checks that the network is in phase. When all these conditions are met, the active rectifier can be unlocked and connected to the power circuit, the preload module can be isolated.

1.2.4 - InvertersMD3INV inverters convert the DC Bus voltage provided by the rectifier to generate a three-phase source with variable voltage and frequency to power the motor.This inverter has an IGBT structure and works according to the Pulse Width Modulation (PWM) method. It must be associated with a control module and generate AC voltage from the DC bus voltage (DC/AC converter).

NoteMD3INV modules can also be used as active rectifiers. For more information, see §1.2.2.2

1.2.5 - Parallelisation module

Above 500 kW, the rectifier and inverter chassis shall be installed in parallel to achieve the required power levels (up to 2.5 MW). In this configuration, the first inverter (or active rectifier) chassis must be associated with a control module and each additional chassis must be associated with an MD3PRL parallelisation module.

1.2.6 - The braking moduleIn the case of driving loads with high inertia or load decelerations that are too fast, the energy produced cannot be evacuated, DC Bus overvoltage phenomena may occur. To avoid any risk of unwanted tripping, this energy must be dissipated in resistors via a braking module.The MD3TF braking module is compatible with 6-PULSE, 12-PULSE, 18-PULSE and 24-PULSE power architectures.

NoteThe braking module can also be combined with an Active Front End (AFE) architecture, with an active rectifier, although the system is regenerative. In fact, for very specific applications such as hydroelectricity, it is possible to consider a cut in the supply network and thus the impossibility of reinjecting energy on the network, when tripping. During the shutdown phase, this energy must be dissipated through a braking transistor in a braking resistor. This option can also be integrated into test bench-type applications on synchronous machines.Examples of applications where the braking module is most often used: Ventilation, Press, Lifting, 2 x Cn Braking (Cn = Motor rated torque), Hydroelectricity, Synchronous machine test bench.

Several braking modules can be combined to increase the braking capacity. They must not be mounted in parallel on a single resistor: use as many resistors as braking modules.

1.4 - Cooling methodsPowerdrive MD Smart components generate thermal losses during operation. If these are not evacuated, they lead to temperature rises that may cause the product to trip or components to age prematurely.

Two types of losses will be distinguished:

• Power component losses (rectifier and inverter semiconductors)These losses represent about 80% of the total losses of the variable speed drive that are dissipated by radiators. In order to reduce the losses to be dissipated in the electrical enclosure, the Powerdrive MD Smart has been developed so that its power components’ radiators are located in an exhaust channel (optional accessory). Two types of radiator cooling have been developed to meet the constraints of the installation and the environment: air cooling and liquid cooling.

• Internal lossesThese losses correspond to the total losses generated by the components located inside the enclosure, i.e. the losses of the variable speed drive components (except the power components) but also those of the components needed for the installation (transformer, options, power supplies, relay, etc.). These losses should be evacuated using traditional enclosure cooling methods depending on the temperature and environmental conditions imposed by the components used.

1.4.1 - Air cooling1.4.1.1 - Ventilated power componentsAir cooling is forced convection on the Powerdrive MD Smart. It is carried out by means of fans mounted on each power module. Losses are directly discharged through an air channel mounted on the radiators of the power modules. This air channel is provided as an option.

• Ventilated rectifiers or inverters: AF version

Ventilations Ventilation

Example: an MD3INVAF inverter Example: an MD3RECxAF rectifier MD3TUNyyTx

Note: The MD3TUNyyTx fan tunnels provide a good cooling of the components of the Powerdrive MD Smart (inverter and rectifier).There are different ventilation tunnels depending on the size of the power module to be cooled (x=1,2,3), and their composition (yy=R(regen), 6P(6 pulse)). See §3.4.

In this version, all Powerdrive MD Smart power modules are mounted on a cold plate (CL version) on which the heat sinks are attached.

Advantages: • The Liquid Cooling Circuit is managed outside the electrical box to facilitate the management of any leaks or condensates.• Separation of liquid circuit and electrical components• Removal of modules for maintenance can be performed without interrupting the cooling circuit.• Limited downtime during maintenance.

1.4.3 - Internal loss managementLosses generated inside the enclosure are from power and passive components. In order to evacuate them several methods are possible:

• Extractors and filters: when the room temperature is always below the required enclosure temperature and the enclosure is in a low-pollution environment, fans are the easiest and most efficient solution.

While operating, fans generate an overpressure in the electrical box. The filters in the door must be positioned in the lower part and the fan in the upper part or vice versa.

• Air conditioners: if the environment does not allow sufficiently filtered air to flow between the outside and inside of the enclosure, thus ensuring the integrity of the components, then consideration will be given to a waterproof and air-conditioned solution.

Where the temperature required in the electrical box is to be at or below the ambient temperature and/or the ambient air is too polluted, it is preferable to use air conditioner(s).

When air conditioners are used to cool the air in the enclosures, it should be noted that the moisture from the air expelled into the enclosure increases due to the cooling of the air conditioner and may fall below the dew point (the temperature at which the water vapour contained in the air condenses into water). It is therefore essential to keep the moisture inside the enclosure at a higher level in order to avoid any risk of premature material degradation.

Example:For a temperature Tair = 35°C and a humidity of 60%.At intersection A on the graph, the dew point temperature is 26°C.The temperature inside the enclosure must therefore not be less than 26°C.

• Air/water heat exchangers: when the ambient air is too aggressive for the use of standard air conditioners and a high IP protection rating is required, then it is preferable to use an exchanger(s). In addition, the air/water exchanger does not dissipate heat losses from the electrical box in the environment where the enclosure is located, as losses are discharged into the heat transfer fluid.

Formula for calculating air flow rate

V = 3.1 x PV [m3/h] ∆T

V[m3/h] : filter fan air flow ratePV[Watt] : loss of dissipation (thermal power generated in an enclosure by loss of dissipation of components)∆T : difference between ambient and indoor air temperature

2.2 - Determination of the continuous output current (Isp)The various components presented in Section §1 are intended to be assembled in order to make a Powerdrive MD Smart variable speed drive.Before you can select the component references, it is necessary to know the continuous output current (Isp) required to drive the motor.

This requires determining the conditions under which the variable speed drive will operate.The continuous output current Isp of the Powerdrive MD Smart shall be determined for optimal operation with a centrifugal or constant torque machine with reduced overload, at a temperature ≤ 40°C (chassis enclosure temperature), an altitude ≤ 1000 m above sea level, a chopping frequency of 3 kHz and a speed ≥ 10 Hz in steady state.If the application complies with these conditions, the component selection tables may be used directly, see Section 2.3.Outside these normal conditions of use, the continuous output current of the application shall be determined. Detailed explanations of operating temperature, altitude derating, low frequency or high chopping frequency operations, and reduced/maximum overload applications are provided in the following paragraphs.

If the user decides to increase this value, it is necessary to downgrade the standard Isp continuous output current. The variable speed drive component selection tables in §2.3 take this derating into account and indicate the Isp values for a chopping frequency value of 4, 6 and 8 kHz.

These options can be used with an MD3INV active rectifier. It is therefore necessary to know their characteristics so that they can be supplied by the variable speed drive integrator from the supplier of his choice.However, these options can be ordered at Leroy-Somer. In this case, refer to the Appendices to this document.

• RFI filterThe use of RFI filters helps to reduce the level of emission of radiated and conducted radio frequency signals. They enable MD3INV components to comply with the EN61800-3 standard on variable speed drives. The Powerdrive MD Smart rectifiers have been tested with Schaffner filters. The following tables show the compliance levels achieved and the types of filters used.

Main contactorThe line contactor is a necessary device to ensure the connection / disconnection of the power system’s active rectifiers. It is also used for the implementation of the "EMERGENCY STOP" safety function, which is used to electrically and automatically isolate the active rectifier from the power supply network.It is a switching device only, it does not provide any protection function during a short circuit or a line surge It is therefore the responsibility of the integrator to ensure this protection by adding equipment for this function (circuit breaker, switch-splitter-fuse, etc.).The line connector performs the switching and protection role.In general, the line current and the breaking capacity are the main criteria for choosing a contactor. In addition, the rated current of the contactor shall be greater than or equal to the rated input current of the active rectifier chassis.The contactors to be used are of category AC-1 (resistive switching) which have a maximum breaking capacity equal to approximately 1.5 times their rated load.When shutting down the converter or tripping (default), the sequence to follow is:• Locking the STO inputs of the active rectifier control module to lock the power stages (IGBT)• Opening of the line contactor for electrical insulation of the power supply system.See section §4.5.1 for the power and control cabling diagram.

The md3preload module is equipped with thyristors. It is compatible with all network voltages (400 V - 480 V - 690 V), but also with all the capacities of active rectifier chassis, alone or in parallel.

However, the MD3PRG thyristors must be protected and the installation of a preload contactor is necessary in order to create a bypass between the preload phase (start up) and the regime established on the power system. When the preload is complete the line contactor is closed and the preload contactor is open.

The protection of the preload circuit as well as the preload contactor is the responsibility of the customer.

An MD3TF braking module incorporates an IGBT transistor and a control circuit. In order to increase the braking capacity, several modules can be mounted in parallel, provided that each module flows its energy in its own resistor. A thermal relay must be installed in series in the power circuit as thermal protection

2.7.6.2 - Braking resistorThe resistor converts excess DC BUS energy into heat. It is connected to the braking module. The braking resistor shall be mounted outside the enclosure to limit the cooling level of the enclosure.Rerfer to the notice ref. 5560 for calculation of braking resistance according to application (www.leroy-somer.com).

Example of thermal protection calculationP = U*I, if U = R*Ithen: P = (R*I)*I = R*I²I = √(P/R)

Take for example a resistance of 55000 kW and 5 OhmsI = √(55000/5)I = 104.88 A = 105 ASo a 105 A heat relay is required to protect the resistor.

• P1 connector (for PC communication)

The USB-B connector allows communication via PC using SYSTEMIZ software. This connector also allows the firmware version of the control module to be updated (Contact Leroy-Somer).

In accordance with the requirements of EN 60950, the USB link can only be used through a device that provides 4 kV insulation.

• PB1 connector (for a setup interface)

• Connection

Terminals Description1 0V2 Rx\, Tx\3 Rx, Tx4 24 V

It is a standard RS485 terminal that allows the connection of a setup interface or to communicate in Modbus RTU, under certain conditions:

• Operation with an HMI + Cableless- If Cableless is enabled, the HMI is no longer in use.- The HMI will resume when the Cableless connection is disabled

• Operation without an HMI + Cableless- If the Cableless function is enabled then the PB1 RS485 port cannot be used in Modbus. The MDX MODBUS option must be

added to communicate with the MODBUS variable speed drive.- If the Cableless function is disabled then the PB1 RS485 port can be used in Modbus provided the transmission speed is 115200

baud

Note: for info, the speed 115200 baud of this port prohibits the use of an MDX keypad option.

2.7.9 - Customisation card The customisation card is delivered systematically with the inverter chassis, it allows the current returns of the inverter to be calibrated and indicates to the control module the “LS model” of the solution created. The basic control module and the parallelisation module come with a "neutral" customisation card. This card is only available for transport so as not to damage the connection. When the control module and the parallelisation module are connected, it will of course be necessary to replace it with the customisation card delivered with the MD3INV inverter chassis, in order to ensure proper operation.

3 - MECHANICAL INSTALLATION

• It is the owner or user’s responsibility to ensure that the assembly, installation, cabling and testing of the Powerdrive MD Smart variable speed drive and its options are carried out in accordance with the property and personal safety legislation and regulations in use in the country in which it is installed.

• Variable speed drives must be installed in an environment free of conductive, smoked, corrosive and condensing dust, gas and fluids (Class 2 according to IEC 664.1). The variable speed drive shall not be installed in risk areas except in an appropriate enclosure. In this case, the installation must be certified.

• In atmospheres subject to condensation, install a heating system (to be turned off when the variable speed drive is in operation). It is preferable to order the heating system automatically.

3.1 - Checks upon receipt

Before installing the various components of the POWERDRIVE MD Smart, ensure that: - the component has not been damaged during transportation, - the information on the nameplate is compatible with the supply network.

3.2 - Handling

• Ensure that the handling means are suitable for the mass to be handled.

• Some elements are equipped with 4 lifting rings.

• Most chassis in the range weigh more than 15 kg.

For handling, use a lifting beam that complies with the characteristics shown in the diagram below. RECTIFIER AND INVERTER chassis must be handled horizontally.

To ensure the temperature of the above coolant, a 3-way valve or variable speed pump must be installed.

Note: - The recommended fluid is glycolated water, mix at 25%, the maximum temperature is 40°C.- Salt water is prohibited.- We recommend the use of an external cooling loop so that the fluid is used in closed circuit.- A controlled heating system must be installed to keep the minimum temperature of 5° C inside the enclosure at start-up (to be

disabled when the variable speed drive is in running order).

3.5.2 - Recommendations• Characteristics of the cooling liquid :Since the most stressed components of the drive are completely cooled by liquid, The characteristics of the liquid directly affect the quality of the cooling and therefore the lifetime of the variable speed drive. Prevent electrochemical corrosion and sediment obstruction by ensuring that the cooling agent used meets the following criteria:• pH 7.5 to 8.5• CaCO3 alkalinity: 100 to 400 mg/l• chloride Cl-: <200 mg/l• conductivity: 1000 to 1500 μS/cm• Liquid temperature increase :At steady speed The maximum heating of the coolant at the variable speed drive outlet with the recommended minimum flow is 8°C.• Protection against electrochemical corrosion:When an external coolant loop is used, it is recommended to add an inhibitor to prevent electrochemical corrosion. If there is no external loop, this corrosion shall be avoided by using materials compatible with the materials used in the cooling circuit of the variable speed drive: question to be asked.• Protection against sediment obstructions:A coolant with too many particles can speed up the sediment-induced blockage of radiators, so it is recommended that filters be installed upstream of the drive fluid system.• Protection against stopping the circulation of liquid: To avoid harmful overheating, a liquid circulation monitoring relay must be cabled to the variable speed drive’s safety chain.

3.5.3 - Drainage and maintenanceThe frequency of drainage and maintenance cycles depends on the quality of the coolant. These cycles must therefore be determined based on the quality of the fluid used and designed according to the installation. Temperature elevations caused by passive components and circuit boards can create condensation on heat sinks or pipe fittings, depending on the humidity in the air and the temperature difference between the interior of the enclosure and the cooling circuit.It is therefore advisable to have a coolant temperature as close as possible to the internal temperature of the enclosure, depending on the use of the variable speed drive. This can be achieved by reducing the ambient temperature or increasing the temperature of the fluid (respect the maximum temperatures described in section 3.5.2).

All connection work must be carried out by qualified electricians according to the laws in use in the country where the variable speed drive is installed. This includes earthing or bonding to ensure that no part of the equipment directly accessible to the user can be at mains potential or at any other voltage which may be dangerous.

• The variable speed drive must be powered through an approved breaking device in order to be able to safely turn it off.

• The power supply of the equipment shall be protected against overloads and short circuits.

• Voltages on the network, motor, braking resistance or filter connections can cause fatal electrical shocks. In all cases the protective plates supplied with the variable speed drive must be correctly installed to protect the user from direct electrical contact.

4.1 - Power network4.1.1 - Neutral IT point connectionFor installations with a neutral IT point connection, the link bar connecting the EMC capabilities to the ground should be opened as shown below. Active Front End (AFE) versions are not affected.

In any case, the ground links intended to ensure the protection of people, by connecting the metal masses to the ground by a cable, can not replace the ground connections (see IEC 61000-5-2).The immunity and the level of radio frequency emission are directly related to the quality of the ground connections.

4.1.2.1 - Equipotential protection or EP circuitThe EP terminal shall be located close to the terminals of the phase conductors. It must be marked with the letters EP. The minimum section is given by the table below, it cannot be less than 10 mm².

4.1.2.2 - ShieldingShielding is necessary to mitigate (dampen) magnetic, electric or electromagnetic disturbance fields. Use dense-braided shielded cables where possible (coverage rate) > 80%). Avoid using shielded ribbon cables.

Generally:• Separate the control and power cables as much as possible (do not run them through the same pins).• Signal cables integrated into the motor cable (i.e., the motor’s thermal probe, the motor’s brake) receive significant disruptions

through the cable capacity. The shielding of these signal cables shall be connected to the ground near the motor cable to prevent the propagation of this parasitic current in the control system.

• The shielding of power conductors provides a preferred path for common mode currents to return to their original point of origin without dispersing into other possible paths (equipotential conductors, piping, building structures, etc.). It significantly reduces the levels of electromagnetic emissions conducted and radiated. For this reason, the use of shielded cables between variable speed drive and motor is imperative to ensure compliance with EMC emission standards (IEC 61800-3, etc.). Shielded cables also limit the shaft tension and the risk of bearing damage.

• the cable shielding must be connected to ground potential at both ends. Only a connection at both ends allows a good immunity in the high frequency range. In exceptional cases, shielding can only be connected to the ground potential at one end. Only low frequencies will be amortized. The connection of one end of the shielding may be useful when:

- It is not possible to install an equipotentiality cable. - It is not necessary to transmit analogue signals (a few mVs or μA).

The disruptive currents are derived to the ground through the shielding bar connected by a conductive connection to the housing. In order to prevent these derived currents from becoming sources of disturbance themselves, it is essential to make a low impedance connection to the protection conductor.

For more details, please refer to the Guide to Good Practices ref.5626, which can be downloaded from www.leroy-somer.com.

- For control cables, use shielded twisted cables and connect the shielding to the collar of the MD3CTL shielding module.

A shielding connection calliper comes with each option. To secure it, screw the calliper over the shielding collars of the control cables (the rightmost shielding collar must be removed).

4.1.2.3 - Cable routing

Sensitive cables should preferably be routed through a metal chute, separate from the power cables or remote control.

This can be simply a U-shaped support of the chassis (connected in several points to the enclosure’s grounding).

Shielded or sensitive cables must avoid running along power cables or bars or disruptive cables. However, a sensitive or shielded cable may cross a disruptive cable at a right-angle.

In the enclosure, it is possible to place a ground bar, connected to the EP point of the enclosure (without specific request of the specification of the case), on which it will be easier to make mass braid connections.

In case of parallel routing of sensitive cables and power cables or bar, a distance of 20 cm shall be respected.

Non-exhaustive list of sensitive signals:

Class or Group Type of signal

1Very sensitive

- Low-level circuit, analogue input or output- Measurement circuit, variable speed drive cabling, driver control panel, quick

link between control card, on-the-fly recovery cable, bus measurement cable, etc...

2Sensitive

- Digital circuit, field bus cable, CAN OPEN, Profibus, etc.- All-or-nothing output circuit, encoder signals- Low level continuous power supplies

3Disruptive

- Inductive load control circuit (coils)- Main power supplies connected to power devices- Relaying

4Very disruptive

- Switched power circuit (frequency variable speed drives, switched-mode power supply)

- Power circuit

The following rules must be observed:

- Ensure an equipotentiality of low and high frequency masses between equipment (in particular between variable speed drive chassis and RFI filters and between all chassis connected by shielded cables)

- Separate disruptive components from sensitive components in enclosures.

- Separate energy cables from low-level cables.

- Treat connections, ground connections, ground continuity.

- Equip all inductive loads with a pest control product.

For powers > 500 kW, MD3REC rectifiers and MD3INV inverters are connected in parallel in order to achieve the desired power levels.

In this configuration, we distinguish:

• A "MASTER" assembly consisting of rectifier, inverter and control chassis equivalent to a 6-PULSE architecture of less than 500 kW. The control card controls all the power modules.

• One or more "SLAVE" assemblies consisting of rectifier, inverter and parallelisation chassis. The parallelisation module is the element that permits the installation of the different power chassis in parallel in order to obtain the desired power.

• 400V -10% to 480V +10%

Here are the possible parallel layouts according to the models:

Green boxes tell us how many products to install in parallel. A maximum of 5 570 T modules can be installed in parallel, giving a calibre of 2850 T (see table above) equivalent to a power of 2.5 MW.

4.9 - Brake module cabling

• InstructionsConnect the braking resistance to the MD3TF400 transistor. • Connect a thermal relay (not supplied), calibrated to the current corresponding to the braking resistor (see §2.6.6) • Connect the P14 flat cable to the corresponding connector on the variable speed drive’s interface card (flip the control card to the

interface card) • Connect DC+ and DC- to DC bus bars on the variable speed drive with connecting terminals (e.g. Rittal Ref 3457.500)

• Cabling

• Recommendations: before installing a braking resistor, ensure that the fire risks associated with its presence have been eliminated.

• A braking resistor shall be mounted outside the enclosure to limit the cooling level of the enclosure. Ensure that it is integrated into a ventilated metal housing connected to the ground, so as to avoid direct contact.

• The braking resistor shall be wired in series with a thermal relay calibrated to the effective current of the resistor. Triggering the relay must immediately cause the variable speed drive to stop and disconnect from the power network.

• Specific warnings to indicate the presence of a high temperature shall be affixed to the resistor. • The braking resistor shall be installed in such a way as not to damage the surrounding components by its

heat dissipation.

4.10.1 - Cabling connectionsThis table shows the permissible current in a silicone cable for a core temperature of 85°C, at different ambient temperatures. After installation, the cables can be doubled or tripled. The correction factor gives ampacity under these conditions. These data refer to the brand of the cable types OMERIN 3512 and are adapted according to the reference used. This data is only for internal connections with limited lengths at the perimeter of the enclosure.

In the case of a smoothing inductance, do not exceed 2 m.

4.11 - Control terminal cabling4.11.1 - Remote controlIn case of a return to factory settings, the variable speed drive will configure its inputs as below.

The Systemiz interface makes it easy to set up the variable speed drive for most common applications. For more specific applications, it is necessary to change the advanced settings of the variable speed drive.

4.11.4 - STO-1 / STO-2 inputs: safe torque off functionThe STO-1 and STO-2 inputs are safety inputs that lock the variable speed drive's output so that it does not transmit torque to the motor.They are independent of each other. They are made by simple hardware not connected to the micro-controller, which acts on two separate stages of the control of the output port to IGBT.To unlock the variable speed drive, the STO-1 and STO-2 inputs must be connected to the +24 V source.Opening at least one of the inputs locks the output port.

The use of these 2 inputs allows the "Safe Torque Off" function to be activated with a logic with 2 separate channels.In this configuration, the “Safe Torque Off" function is guaranteed with a very high level of integrity in accordance with the requirements of standards:- EN 61800-5-2- EN/ISO 13849-1: 2006; PLe- IEC/EN 62061: 2005 ; SIL3(CETIM Approval No. CET0047520)

In a safety chain, this integrated functionality allows the drive to replace a contactor to ensure that the motor switches to free wheel mode.The STO-1 and STO-2 inputs are compatible with the self-tested logic outputs of controllers such as APIs, for which the test pulse is 1 ms maximum.If the information transmitted by the 2 inputs is not identical, a variable speed drive trip is generated. The RL1 relay opens and the variable speed drive indicates a “t.r./63” trip on the variable speed drive 2-digit display or “STO inconsistency” with a configuration interface.For proper implementation, the power and control connection diagrams outlined in this manual shall be observed.

• The STO-1 / STO-2 inputs are safety features that must be incorporated into the safety system of the whole machine. As with any installation, the installer will have to carry out a risk analysis on the whole machine and determine the safety category to which the installation will have to comply.

• When opened, the STO-1 and STO-2 inputs lock the variable speed drive, not providing a dynamic braking function. If a braking function is required before the variable speed drive is securely locked, a safety relay shall be installed to automatically control locking once braking is complete.

• If braking is to be a safety function of the machine, it must be provided by an electromechanical solution as the dynamic braking function by the variable speed drive is not considered safe.

• The STO-1 / STO-2 inputs do not provide electrical insulation. Before any intervention, the power cut must therefore be ensured by an approved sectioning device (switch, circuit breaker, etc.).

• The switch option supplied with the variable speed drive does not isolate the input bar sets from the variable speed drive. It must be associated with a cut-off unit located on the switchboard. In all cases, access to the inside of the variable speed drive may only be made once the power distribution network has been cut off.

TESTING


TEST

5 - TESTING For commissioning and configuring the Powerdrive MD Smart variable speed drive, refer to manual 5641, available on www.leroy-somer.com.

Once the various components of the Powerdrive MD Smart variable speed drive have been integrated into the enclosure, the installer must ensure that the unit functions properly.

All installation, commissioning and maintenance work shall be performed by qualified and authorised personnel.• When a variable speed drive-detected safety warning causes the motor to shut down, residual fatal voltages are still present on

the terminal blocks and in the variable speed drive.• The variable speed drive shutdown function does not protect against the high voltage on the terminal blocks.• Do not work on the variable speed drive or motor without opening and padlocking the control panel.• Optional integrated variable speed drive network severing equipment does not isolate the variable speed drive’s input bar sets.

During installation and maintenance, ensure that the power line is open.• When the variable speed drive is operating a permanent magnet motor, the interlocking device between the variable speed drive

and the motor must be opened to prevent the risk of a return of motor voltage. If there are no sectioning devices present, it is necessary to ensure that the machine shaft is blocked while work is carried out.

• After the variable speed drive is turned off, the external control circuits may maintain a dangerous voltage level. Verify that these circuits are powered off before working on control cables.

• Wait 15 minutes and then ensure that the voltage of the continuous bus is less than 40V.• After drive operation, the radiator may be very hot, keep away from it (70°C).• After drive operation, check that the sequence of phases is correct when re-connecting the motor cables.• During testing, all protective covers must remain in place.• Before conducting dielectric or power-on tests, power off the variable speed drive and disconnect the motor.

5.1 - Self-testing and diagnostics 5.1.1 - Control module MD3CTLThis test consists of checking the proper functioning of the MD3CTL module.

Before validating the test: - In the case of an external power supply, cut off the power and leave only the power supply of the electronics (MD3CTL terminal

block PM6). - In the case of an internal power supply to the electronics, disconnect the internal cabling and connect an external power supply, in

order to cut off the power and leave only the electronic power supply (MD3CTL terminal block PM6). 1) Disconnect the PX1 and PX3 connectors from the control card2) The safe torque inputs of the STO-1 and STO-2 torque shall be closed3) Turn on the auxiliary power supply, the test only starts if the bus voltage is less than 50 V4) Initiate the card’s self-test procedure with parameter 17.015) Check the result of the self test in parameter 17.05

At the end of the test, an automatic reset is performed (equivalent to a reset when the variable speed drive is turned off and on), in particular, a reset of parameters 17.33 to 17.39, 17.42 to 17.49, 17.52 to 17.59). In the event of an error, follow the instructions in the Powerdrive MD Smart commissioning manual ref. 5641

6) Cut the power to the electronics

After testing, reconnect everything.

5.1.2 - PowerThis test consists of checking the proper functioning of the power circuits.

During this test, current is circulating in the motor.

Power on the variable speed drive, power supply and start the power test with parameter 17.02.The power test is validated. If the bus voltage is greater than 70 V, the variable speed drive waits for the natural discharge of the bus (the wait may take longer than 5 minutes). In order for the test to work, the safe torque off inputs must be closed. Otherwise, a “Diagnostic” trip is generated and the test result 17.06 indicates “Open STO Failure”.

The results are displayed in 17.06 following the instructions outlined in the Powerdrive MD Smart commissioning manual ref. 5641.

154

TESTING


TEST

Note: this self-test can be performed every time the variable speed drive is powered on, to check the power elements. It lasts less than 5 seconds since in this case the bus is not loaded. This self-test is adjustable in 17.03..If the 2 tests are successful and without defect then an operation test can be performed.

5.2 - Operating testThis involves running a motor and checking the waveform of the current in and out of the variable speed drive.

5.2.1 - Necessary hardware:- A test platform suitable for the size of the variable speed drive.- A current clamp.- Two oscilloscope current clamps- An oscilloscope.- A button box.

MAINTENANCE


MAIN

TENA

NCE

6 - MAINTENANCEUser maintenance and troubleshooting of Powerdrive MD Smart variable speed drives is extremely low. The routine maintenance operations are as follows:

• MaintenancePrinted circuit boards and variable speed drive components do not normally require maintenance. Contact your nearest authorised dealer or repairer if there is a problem.

CAUTION:Do not disassemble the printed circuit boards during the warranty period. This would immediately invalidate the warranty.Do not touch the integrated circuits or microprocessor with your fingers.Periodically check the tightening of the powered down power connections. Port filters should be checked, cleaned (washable) and changed regularly according to their condition.

• Preventive maintenanceSystem action recurrenceCheck tightening torque of power connections after 1 yearReplace internal ventilation after 5 years

• StorageThe Powerdrive MD Smart incorporates aluminium electrolytic capacitors.After 12 months of storage, it is therefore necessary to turn on the variable speed drive for 5 hours at the rated operating voltage, then redo the operation every 6 months.After 36 months of storage, a capacitor reforming operation is required.This involves applying a continuous voltage progressively on the capacitor benches, until voltage values close to the rated values are achieved, while ensuring that the dissipated powers do not exceed the maximum values allowed by the manufacturers.A procedure is available upon request from your usual Nidec Leroy-Somer contact.

7.6 - AC supply specificationEquipment suitable for use on a circuit capable of delivering not more than the values listed in the table of section 8.5.3.

7.7 - Motor overload protection and overspeed protectionThe drive does not incorporate solid state overload protection for the motor load. The drive provides overspeed protection. However, it does not provide the level of protection afforded by an independent high integrity over-speed protection device.

7.8 - PX1, PX2, PX3 and P2 customer interface• The Powerdrive MD Smart inputs have a positive logic configuration. Using a drive with a control system which has different control logic may cause unexpected starting of the motor.

• The Powerdrive MD Smart control circuit is isolated from the power circuits by single insulation. Its electronic 0V is connected to the connection terminal on the outer protective conductor (earth terminal).• The installer must ensure that the external control circuits are isolated against any human contact.• If the serial link port (P2) or the control terminals (PX1, PX2) need to be connected to circuits complying with SELV safety requirements, additional 4kV insulation barrier must be inserted to maintain the SELV classification (see EN 61140). • USB port (P1): Use restricted to Cat. No. MDX-USB isolator option by Nidec Leroy-Somer (ordering code 4808979) for ensuring a supplemental insulation for at least 600 V between the 24V circuits and user.The PX3 output relay is limited for OVCII (Overvoltage Category 2) use (RL1 and RL2 must have the same polarity). The voltage rating between two consecutive terminals must not exceed 150Vrms.
