4 Mechanical Installation

4.1 Before you begin

The drive may only be installed if

• The entries on the nameplate of the drive and/or the output voltage of the frequencyinverter match the voltage supply system

• The drive is undamaged (no damage caused by transportation or storage)

• It is certain that the following requirements have been met:

– Ambient temperature between –20 °C and +40 °C1)

– No oil, acid, gas, vapors, radiation, etc.– Installation altitude max. 1000 m above sea level– Note the restrictions for encoders– Special versions: Drive configured in accordance with the ambient conditions

4.2 Preliminary work

Motor shaft ends must be thoroughly cleaned of anti-corrosion agents, contamination orsimilar (use a commercially available solvent). Do not allow the solvent to penetrate thebearings or shaft seals – this could cause material damage!

Extended storage of motors

• Please note the reduced grease utilization period of the ball bearings after storageperiods exceeding one year.

• Check whether the motor has absorbed moisture as a result of being stored for a longtime. Measure the insulation resistance to do this (measuring voltage 500 V).

The insulation resistance (→ following figure) varies greatly depending on thetemperature! The motor must be dried if the insulation resistance is not adequate.

It is essential to comply with the safety notes in Section 2 during installation!

1) Minimum temperature for motors with backstop: –15 °C. Note that the temperature range of the gear unitmay also be restricted (→ gear unit operating instructions)

4 Installing the motorMechanical Installation

Drying the motor Heat up the motor

• with hot air or

• using an isolation transformer

– Connect the windings in series (→ following figure)– Auxiliary AC voltage supply max. 10 % of the rated voltage with max. 20 % of the

rated current

The drying process is finished when the minimum insulation resistance has beenattained.

Check the terminal box to see whether

• The inside is clean and dry

• The connections and fixing parts are free from corrosion

• The joint seals are OK

• The cable glands are sound, otherwise clean or replace them.

4.3 Installing the motor

The motor or gearmotor may only be mounted or installed in the specified mountingposition on a level and torsionally rigid support structure which is not subjected toshocks.

Carefully align the motor and the driven machine to avoid placing any unacceptablestrain on the output shafts (observe permissible overhung load and axial thrust data!).

Do not butt or hammer the shaft end.

Use an appropriate cover to protect motors in vertical mounting positions fromobjects or fluids entering (protection cowl C).

Ensure an unobstructed cooling air supply and that air heated by other apparatus cannotbe drawn in or reused.

Balance components for subsequent mounting on the shaft with a half key (motor shaftsare balanced with a half key).

Any condensation drain holes will be sealed by plastic plugs and should only beopened when necessary; open condensation drain holes are not permitted, asthis would invalidate higher classes of enclosure.

If using brake motors with manual brake release, screw in either the hand lever (withself-reengaging manual brake release) or the setscrew (with lockable manual brakerelease).

Note the following for encoder mounting:

Foot-mounted motors CT/DT71, CT/DT90, CV/DV132M, CV/DV160L must be mountedon supports because the radius of the cover is greater than the shaft height.

4Installation tolerancesMechanical Installation

Installation in damp locations or in the open

If possible, arrange the terminal box so the cable entries are pointing downwards.

Coat the threads of cable glands and pocket caps with sealant and tighten them well –then coat them again.

Seal the cable entry well.

Thoroughly clean the sealing surfaces of terminal boxes and terminal box covers priorto reassembly; gaskets must be glued in on one side. Install new gaskets to replaceembrittled ones!

Restore the anticorrosive coating if necessary.

Check the enclosure.

5 Wiring notesElectrical Installation

5 Electrical InstallationIt is essential to comply with the safety notes in section 2 during installation!

Switch contacts in utilization category AC-3 to EN 60947-4-1 must be used forswitching the motor and the brake.

Note the additional provi-sions

In addition to the generally applicable installation regulations for low-voltage electricalequipment (e.g. in Germany: DIN VDE 0100, DIN VDE 0105), it is also necessary tocomply with the special provisions on setting up electrical machinery in potentiallyexplosive atmospheres (operating safety regulations in Germany: EN 60 079-14;EN 50 281-1-2 and specific provisions for the machine).

Using the wiring diagrams

The motor must only ever be connected as shown in the wiring diagram included withthe motor. Do not connect or start up the motor if this wiring diagram is missing.You can obtain the valid wiring diagram free of charge from SEW-EURODRIVE.

Cable entries The terminal boxes have metric threaded holes according to EN 50262. All metric cableentries are supplied with ATEX certified closing plugs.

To establish the correct cable entry, the sealing plugs must be replaced by ATEXapproved cable glands with strain relief. Select the cable screw fitting according tothe outer diameter of the cable used.

All cable entries that are not required must be sealed off with an ATEX certifiedclosing plug after completion of the installation (→ Maintaining the enclosure).

Equipotential bonding

In accordance with E N60079-14, IEC 61241-14 and EN 50281-1-1, the motor may haveto be connected to a equipotentional bonding system.

5.1 Wiring notes

Comply with the safety notes during installation.

Protecting brake control systems against interference

Do not route brake cables alongside switched-mode power cables, as otherwise thereis a risk of disrupting brake control systems.

Switched-mode power cables include in particular:

– Output cables from frequency and servo controllers, converters, soft start units andbrake units

– Feeder cables for brake resistors and similar options


5Special aspects for operation with a frequency inverterElectrical Installation

Protecting motor protection devices against interference

To protect SEW motor protection devices (temperature sensors TF, winding thermostatsTH) against interference:

– Route separately shielded feeder cables together with switched-mode power lines inone cable

– Do not route unshielded feeder cables together with switched-mode power lines inone cable

5.2 Special aspects for operation with a frequency inverter

When motors are powered from inverters, you must adhere to the wiring instructionsissued by the inverter manufacturer. It is essential to observe the operating instructionsfor the frequency inverter.

5.3 Improving the grounding (EMC)

For improved, low-impedance grounding at high frequencies, we recommend using thefollowing connections with the DR/DV/DT AC motors:

• Sizes DT71 ... DV 132S: [1] M5x10 thread rolling screw and 2 serrated lock washersto DIN 6798 in the stator housing.

• Sizes DV112M ... DV280: Screw and 2 serrated lock washers in the bore of the eyebolt.

Install the frequency inverter outside the potentially explosive atmosphere.

Motor/frequency inverter combination

• The listed motor/frequency inverter combinations are mandatory and must be strictlyobserved for category II3G motors (see EN 50021, 10.9.2 "Operation on an inverteror from a non-sinusoidal voltage").

• The listed motor/frequency inverter combinations are recommended for categoryII3D motors. If you want to operate category II3D motors on other frequencyinverters, the maximum speeds/frequencies and the thermal torque limiting charac-teristic curves must also be observed. In addition, we strongly recommend you usea frequency inverter matching the respective power rating.

Winding types The following voltage types are permitted for operation on a frequency inverter.

• Rated motor voltage 230 V / 400 V, frequency inverter supply 230 V:

For operation with a base frequency of 50 Hz, the motor must be in delta connection.A base frequency of 87 Hz is not permitted.


For operation with a base frequency of 50 Hz, the motor must be in star connection. For operation with a base frequency of 87 Hz the motor must be in delta connection.


Operation only possible with a base frequency of 50 Hz. The motor must be in deltaconnection.

Due to the higher thermal load, only motors with temperature class F winding must beused in frequency inverter operation.

Temperature class and maximum surface tempera-ture

• Motors in category II3G are in the temperature class T3.

• Motors in category II3D have a maximum surface temperature of 120 °C or 140 °C.

• Motors in category II3GD are in the temperature class T3 and have a maximumsurface temperature of 120 °C or 140 °C.

6Asynchronous servomotors: Frequency inverter assignmentOperating Modes and Limit Values

6.8 Asynchronous servomotors: Frequency inverter assignment

General information

Install the frequency inverter outside the potentially explosive atmosphere.

Permitted frequency inverters

The highest dynamic properties and control quality is achieved by using frequencyinverters from the MOVIDRIVE® series. The frequency inverters listed in the table"CT/CV.../II3D combinations – MOVIDRIVE®" must be observed.

The use of other types of frequency inverters is permitted. Make sure that the permittedoperating data of the motors (see Sec. 5.6 on page 46) is not exceeded.

Permitted operating modes for MOVIDRIVE® frequency inverters

To ensure highest dynamic properties, frequency inverters of the MOVIDRIVE® seriesmust be started up in a CFC operating mode. VFC operating modes are also permitted.

Supply voltage of the frequency inverter

The supply voltage of the frequency inverter must not fall below the minimum value of400 V.

The maximum permitted supply voltage must be limited to 500 V. Otherwise, thefrequency inverter currents can cause dangerous overvoltages to build up at the motorconnection terminals.

EMC measures The following components are permitted for the MOVIDRIVE® frequency inverters:

Line filters of the NF...-... series

Output chokes of the HD... series

Output filters of the HF.. series must not be used! If using a different type offrequency inverter, you must ensure that the output connection of the frequencyinverter to improve the EMC characteristics does not significantly reduce theoutput voltage.

Before startup, make sure that

• The drive is undamaged and not blocked

• The measures stipulated in the "Preliminary work" section are performed afterextended storage

• All connections have been made properly

• The direction of rotation of the motor/gearmotor is correct

– (motor rotating clockwise: U, V, W to L1, L2, L3)

• All protective covers have been fitted correctly

• All motor protection equipment is active and set for the rated motor current

• The self-reengaging manual brake release is used in case of hoist drives

• There are no other sources of danger present

During startup, make sure that

• The motor is running correctly (no overload, no speed fluctuation, no loud noises,etc.)

• The correct braking torque is set according to the specific application (→ Sec. "Tech-nical Data")

• In case of problems (→ Sec. "Malfunctions")

7.2 Necessary frequency inverter parameters

General information

Use the appropriate operating instructions for frequency inverter startup.

The current MOVITOOLS® software will lead you through the startup procedure. It isessential to note that the maximum speed must be reset after each guided startup.

Note the following mandatory frequency inverter settings for operating DT../DV.. ACmotors in categories II3G, II3D and II3GD:

It is essential to comply with the safety notes in Sec. 2 during startup!

7Necessary frequency inverter parametersStartup

Setting the maxi-mum frequency or maximum speed

According to the assignment tables for motor/frequency inverter combinations, thefrequency inverter parameters, which limit the maximum motor speed, must be set asfollows:

• If frequency inverters of the MOVITRAC® 31C series are used:

Set parameters 202/212/222 to the limit values

• If frequency inverters of the MOVITRAC® 07 series are used:

Set parameter 302 to the limit value

• If frequency inverters of the MOVIDRIVE® and MOVIDRIVE®compact series areused:

Set parameters 302/312 to the limit value

Setting the current limitation

According to the assignment tables for motor/frequency inverter combinations, thefrequency inverter parameters, which limit the maximum motor current, must be set asfollows:

• If frequency inverters of the MOVITRAC® 31C series are used:

Set parameters 320/340 to the value specified in the table.

• If frequency inverters of the MOVIDRIVE® and MOVIDRIVE® compact series areused:

No setting is required!

Setting the "IxR" and "Boost" parameters

The parameters must be set as described in the following section. The motor may notbe at operating temperature but must have cooled off to ambient temperature.

MOVITRAC® • If frequency inverters of the MOVITRAC® 31 series are used: Set parametersP328/348 ("Measure motor") to "Yes". Enable drive briefly; the parameters "IxR" and"Boost" are determined and saved. Then, set parameters P328/348 to "No".

Exceptions:

• DT71D4 � connection + MC 31C008

The "IxR" parameter is permanently saved. Set the "Boost" parameter so that no currentgreater than 45 % flows.

• DT80K4 � connection + MC 31C008

The "IxR" parameter is permanently saved. Set the "Boost" parameter so that no currentgreater than 55 % flows.

MOVIDRIVE® • If frequency inverters of the MOVIDRIVE® and MOVIDRIVE® compact series areused:

Set parameters P320/330 ("Automatic adjustment") to Yes. Enable drive briefly; theparameters "IxR" and "Boost" are determined and saved. Then, set parametersP320/330 to "No".

Change "IxR" und "Boost" manually"

7Anti-condensation heating for motors in category II3DStartup

Do not start up the motor in the blocking direction (note the phase angle whenconnecting). Note the direction of rotation of the output shaft and the number of stageswhen mounting the motor on a gear unit. The backstop can be operated once in theblocking direction at half the motor voltage for checking purposes.

1. Isolate the motor from the supply, safeguarding it against unintentional power-up.

2. Remove fan guard [1] and fan [2], unscrew hexagon socket head cap screws [3]

3. Remove the V-ring [4] and sealing flange with felt ring [5]. (Collect the grease forsubsequent use.)

4. Remove the circlip [6] (not for DT71/80); for DV132M-160M, also remove theequalizing rings [10].

5. Pull the carrier [8] and wedge element train [9] completely off the threaded holes [7],turn them by 180° and press them back on.

6. Refill the grease.

7. Important: Do not exert pressure on or hit the wedge element train – danger ofdamaging the material!

8. During the press-in operation – shortly before the wedge element penetrates thelocking collar – slowly turn the rotor shaft by hand in the direction of rotation. Thisallows the wedge element to slide into the locking collar more easily.

9. Install the remaining parts of the backstop by following steps 4. to 2. in reverse order.Note the installation dimension "x" for the V-ring [4].

7.4 Anti-condensation heating for motors in category II3D

In category II/3D motors, connect the anti-condensation heating to the connection leadsmarked H1 and H2. Compare the connection voltage with the voltage specified on thenameplate.

Anti-condensation heating for motors in category II3D:

• Must not be switched on until the motor has been switched off

• Must not be switched on while the motor is operating

8 Motor MalfunctionsMalfunctions

8 Malfunctions8.1 Motor Malfunctions

Problem Possible cause Remedy

Motor does not start up Interruption in connecting harness Check connections, correct if necessary

Brake does not release → Sec. "Brake Problems"

Fuse blown Replace fuse

Motor protection has tripped Check motor protection for correct setting, correct error if necessary.

Motor protection does not switch, error in control

Correct circuit

Loose contact in connecting harness (one phase missing)

Rectify loose contact

Fuse blown Look for and rectify cause (see above); replace fuse

Supply voltage deviates from rated motor voltage by more than 5 %. A higher voltage has a particularly unfavorable effect in motors with a low-speed winding since in these, the no-load current is already close to the rated current even when the voltage is normal.

Adapt motor to supply voltage

Rated operation type (S1 to S10, DIN 57530) exceeded, e.g. through excessive starting frequency

Adjust rated operation type of motor to required operating conditions; if necessary call in a specialist to determine correct drive

Excessively loud Ball bearing compressed, contaminated or damaged

Re-align motor, inspect ball bearing (→ Sect. "Permitted ball bearing types"), grease if necessary (→ Sect. "Lubri-cant Table for Anti-Friction Bearings of SEW Motors"), replace

Vibration of rotating parts Rectify cause, possibly imbalance

Foreign bodies in cooling air passages Clean the cooling air passages

9 Inspection and maintenance intervalsInspection / Maintenance

9 Inspection / Maintenance

9.1 Inspection and maintenance intervals

• SEW-EURODRIVE motors in category 2G (EExe, EExed) are only allowed to be ser-viced and repaired by SEW-EURODRIVE or authorized specialists.

• Only use genuine spare parts in accordance with the relevant valid spare parts list;failure to do so will invalidate the motor's certification for use in potentially explosiveatmospheres.

• The routine test must be repeated whenever parts of the motor relating to explosionprotection are replaced.

• Always install a new brake control system at the same time as replacing the brakecoil.

• Motors can become very hot during operation – danger of burns!

• Secure hoist drives or lower them (danger of falling).

• Isolate the motor and brake from the supply before starting work, safeguarding themagainst unintentional power-up!

• Following maintenance and repair work, make sure the motor has been reassembledcorrectly and that all apertures have been carefully sealed. This is particularly impor-tant for SEW-EURODRIVE motors in categories 2D and 3D. In this case, explosionprotection is particularly dependent on the IP enclosure.

• Regularly clean motors in categories 2D and 3D (zone 21 and zone 22) in order toavoid dangerous buildup of dust.

• Perform safety and functional tests following all maintenance and repair work(thermal protection, brake).

• Explosion protection can only be ensured if motors and brakes are serviced andmaintained correctly.

Unit / unit part Frequency What to do?

Brake BMG02, BR03, BMG05-8, BM15-62

• If used as a working brake:

At least every 3000 hours of operation1)

• If used as a holding brake:

Every 2 to 4 years, depending on operating conditions 1)

1) The periods of wear are affected by many factors and may be short. The machine designer must calculate the required inspec-tion/maintenance intervals individually in accordance with the project planning documents (e.g. "Drive Planning").

Inspect the brake• Measure the brake disk thickness• Brake disk, lining• Measure and set working air gap• Pressure plate• Carrier / gearing• Pressure rings

• Extract the abraded matter.• Inspect the switch elements and change if nec-

essary (e.g. in case of burn-out)

10Work done, working air gap, braking torques of BM15 - 62Technical Data

10.2 Work done, working air gap, braking torques of BM15 - 62

10.3 Permitted work done by the brake

The maximum braking work per brake application shown in the characteristic curvesmust not be exceeded - not even in the case of emergency brake applications.

If you are using a brake motor, you have to check whether the brake is approved for usewith the required starting frequency Z. The following diagrams show the permitted workdone Wmax per cycle for the various brakes and rated speeds. The values are given withreference to the required starting frequency Z in cycles/hour (1/h).

Example for brake in category II3D: The rated speed is 1500 min-1 and the brake BM32 is used. At 200 cycles per hour, the permitted work done per cycle is 9000 J (→Figure 10).

For assistance in determining the braking work, refer to "Practical Implementation:Drives Planning".

10.4 Operating currents

The current values IH (holding current) specified in the tables are r.m.s. values. Use onlyunits to measure the r.m.s. values. The inrush current (acceleration current) IB only flowsfor a short time (max. 120 ms) when the brake is released or during voltage dips below70 % of rated voltage. There is no increased inrush current if the BG brake rectifier isused or if there is a direct DC voltage supply – both are only possible with brakes up tomotor size BMG4.

10.5 Maximum permitted overhung loads

The following table lists the permitted overhung loads (top value) and axial forces(bottom value) of explosion-proof AC motors:

Overhung load conversion for off-center force application

The permitted overhung loads must be calculated using the following formulae in theevent of force application not in the center of the shaft end. The smaller of the two valuesFxL (according to bearing service life) and FxW (according to shaft strength) is thepermitted value for the overhung load at point x. Note that the calculations apply toMamax.
