Activation/deactivation via the PLC
The torque compensation controller can be activated and deactivated directly via PLC
interface signal V380x 5000.4.
For this purpose, the following machine data must be set:
MD37255 MS_TORQUE_CTRL_ACTIVATION = 1
The activated status can be read back via V390x 5000.4.
MD37254 MS_TORQUE_CTRL_MODE is used for configuring the torque distribution.

Tension torque
By specifying a additional torque MD37264 MS_TENSION_TORQUE, you can achieve
tension between the master axis and slave axis when the torque compensation controller is
active. The tension torque is entered as a percentage of the rated torque and is active
straight away.
The tension torque tension torque is applied via a PT1 filter. Specifying a filter time constant
MD37266 MS_TENSION_TORQ_FILTER_TIME > 0 activates the filter.
The tension torque chosen must be high enough to ensure that the resulting torque does not
drop below the minimum required tension even during acceleration. To prevent unnecessary
heating in the motor, you can reduce the tension torque when the motor is at standstill.
Specifying a tension torque without a mechanical coupling produces axis movement.
