General Information


Connection Example for 036214zxy

2 Connection Example for 036214zxy

After unpacking the components at least the following connectors must be wired:

Mains supplySafety contactSpindle connectorConnection to PC

Make sure that the housing is grounded sufficiently and that you use shielded con-necting cables. For detailed information refer to the documentation "Unit AssemblyComplying EMC".

2.1 Power Supply

Pay attention to the permitted supply system types. For detailed information refer tothe hardware documentation and to the documentation "Unit Assembly ComplyingEMC".

2.2 Safety Contact

If the safety contact is not required, connect the pins 1, 3 and 6.

WarningRead the according hardware documentation of your device and payattention to the safety instructions.



2.3 Spindle

2.3.1 Temperature Sensor

Select the motor temperature sensor to be connected on the page "Motor" in the soft-ware. You can parameterize PTC, NTC and KTY84.

You can connect the temperature sensor to connector X16 or to connector X17.

2.3.2 Speed Sensor

The speed sensor can identify the states "Speed zero" and "Speed reached". Con-figure the speed sensor to be connected on the page "Motor measuring system" ac-cordingly.

The speed sensor is connected to X17.

2.4 Choke Modules

With synchronous spindles and spindles of very low inductivity you should usechokes in the motor connections.

Example with choke module 021800039:

WarningSelect the used speed sensor in the software before connecting. The speed sensor can be damaged, when it is configured incorrectlyin the software, because the voltage supply is activated according tothis configuration.



2.5 Analog Reference Value

The analog input can be used as differential input. The scaling can be set via the soft-ware.

2.5.1 Digital Inputs

The function of each digital input is to be configured in the software drivemaster2 via"Parameters → Digital Inputs".

By standard the inputs are configured as follows:

In order to operate the drive via the digital inputs and outputs and the analog refer-ence value setting, three inputs must be connected to +24 V:

D-IN0: Switched onD-IN1: Quick stop type 5D-IN2: Operation enable (start)D-IN3: Parameter set Bit 0D-IN4: Parameter set Bit 1D-IN5: Parameter set Bit 2D-IN6: No functionD-IN7: No functionD-IN8: No function

D-IN0: to switch on the controllerD-IN1: to enable the quick stop commandsD-IN2: to start the spindle



2.6 Notebook/ PC

For the connection with the PC you can order the cable K362103xxxR01.

If there is no COM port available at the PC, the connection can be made via a USBto COM converter. SIEB & MEYER offers the converters 050201 or 0842017 for thispurpose. In future the drives also provide a USB port.


Software Configuration

3 Software Configuration

3.1 Installation

Install the software drivemaster2 using the CD supplied on delivery. The PC to beused for the program must be equipped with the operating system Windows XP orWindows Vista (32 Bit) and sufficient hard disk storage. The installation is largely anautomatic process.

After installation you can start the software drivemaster2.

3.2 Parameterization

3.2.1 Creating a New Drive Parameter Set

Creating a New Project

In a project one or more devices and the corresponding parameter sets are admin-istrated and can be saved together. You can create a project automatically in the on-line mode by searching for online devices or manually with the aid of a wizard. Thewizard is called via "Project → Execute project wizard". Combining the devices ismenu-driven.

Creating a New Parameter Set

After the device has been identified by the software or created by the project wizard,a new parameter set must be created via "Project → New parameters". For this pur-pose a wizard is available that guides you step by step through the parameterization.Select the drive function "High Speed PWM Converter". Thus the drive operates asconverter.

Loading the Drive Parameters

After the project has been created and the motor parameters have been entered, youmust load the parameters into the drive.

For this purpose select one of the following menu items: "Loader → Write project to drives": The whole project is written into the drive(s)."Loader → Write parameters to drive": The motor parameters are written into theselected drive.

You must have administrator rights for the installation. Above all youneed administrator rights when installing the USB driver.



3.2.2 Creating a New Spindle Parameter Set

3.2.2.1 Motor Data

At first the motor must be selected accordingly. The drive function high speed PWMsupports the modes "Asynchronous rotative" and "Synchronous rotative".

The following motor parameters are basically required for the operation:

Rated current⇒ motor data sheet

Peak current⇒ motor data sheet, typically: 1.5...2 times the rated motor current

I²t time⇒ motor data sheet, typically: 2…5 s

Maximum speed⇒ motor data sheet

Minimum speed⇒ motor data sheet, typically: 0…10 % of the maximum speed

Number of pole pairs⇒ motor data sheet

Rotor time constant (only asynchronous motor)⇒ motor data sheet or default (10 ms)

Stator resistance (only synchronous motor)⇒ motor data sheet or measured using a multimeter

Stator inductivity (only synchronous motor)⇒ motor data sheet or measured using a multimeter

Voltage constant (only synchronous motor for breakdown monitoring)⇒ motor data sheet



3.2.2.2 Power Stage

Each speed scaling requires a certain minimum operating frequency. Besides thepower stage operating frequency is dependent on the number of pole pairs.

nmax x number of pole pairs Power stage operating frequency

0 … 30,000 RPM (electr.) 8 kHz

30,000 … 60,000 RPM (electr.) 16 kHz

60,000 … 120,000 RPM (electr.) 32 kHz

120,000 … 240,000 RPM (electr.) 64 kHz

240,000 … 480,000 RPM (electr.) 128 kHz

Example: Maximum speed = 120,000 RPMNumber of poles = 4

⇒

⇒

⇒ Power stage operating frequency = 64 kHz

WarningIf the power stage operating frequency changes, the current control-ler must also be set newly.

3.2.2.3 Current Controller Adjustment

For synchronous motors the amplification Kp and the integral time constant Tn (read-justment time) of the current controller can be configured by the motor parameters.For asynchronous motors it is necessary to adjust these parameters manually.

Manual Setting of the Current Controller

If there are no data for a synchronous motor available or you want to operate anasynchronous motor, you can set the current controller manually.

In order to set the drive manually the drive-setup-tool and the Oscar are required.Both programs are applications in drivemaster2 and can be started out of this soft-ware. The drive-setup-tool operates in the current mode. Set the current to half of therated motor current:

The current controller is set to a low gain (e.g.: or lower) and to a very long

integration time (e.g.: Ti = 500 ms).

The settings are made in the Software drivemaster2 via "Parameters → Current con-troller". After each change of parameters the new data must be loaded to the drive.Afterwards the step response can be recorded by the tool Oscar:

Kp 5VA----=



The Oscar is set as follows: CH1: I-ref. valueCH2: I-actual valueTime: 32 msTrigger condition: Edge+Threshold: 2.0 A

An individual recording is started by the button "Single shot".

Now the gain is increased until the actual current overshoots. It is not important thatthe actual current has not reached the reference current yet. This is accomplishedlater by changing the integral time constant (readjustment time Tn).



Then the gain is reduced just to the value at which the actual current does not over-shoot anymore. By now you have set the correct gain.

Then the integral time constant will be reduced until the actual current somewhatovershoots again. If so, the integral time constant can be increased just to the valueat which the actual current does not overshoot anymore. Thus also the integral timeconstant is set correctly.

With these values the current controller is parameterized correctly.

WarningIf the power stage operating frequency changes, the current control-ler must also be set newly.
