3.5 Torque 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.
