Temporary input

Current controller

Enter the following temporary input values when you begin:

C axis operation must be deselected for commissioning, meaning that no

identical PWM outputs may be entered in MP120.x and in MP121.x.

During commissioning you can use soft keys to switch between wye (star)

and delta connections. With Module 9168 you can interrogate the current

settings in the PLC. You can switch the motor using PLC outputs and activate

the corresponding machine parameters with Module 9163:

Perform the adjustment for wye and delta connection.

• If you do not use the delta connection, set the corresponding machine

parameters to zero.

Adjusting the current controller:

Switch on the control.

Do not acknowledge the "Power Interrupted" message. In the

PROGRAMMING AND EDITING mode of operation, enter the code number

Press the START STEP soft key.

This sends a step function to the current controller and measures the step

response. The height and length of the step function are automatically

calculated by the TNC.
