3.5Torque setpoint limitation

Description

The steps required for limiting the torque setpoint are as follows:

1.Define the torque setpoint and an additional torque setpoint

2.Generate torque limits

The torque setpoint can be limited to a maximum permissible value in all four quadrants. Different limits can be parameterized for motor and regenerative modes.
