6.3.1 Torque control
In this operation mode a torque reference value is specied by the master (S-0-0080).
To protect against overspeed, on reaching the maximum speed a speed controller is
switched on that limits the speed to the maximum value set in the parameters.

The following applies: Tmin_neg = MIN(P 0332, P 330) * P 0329 * P 0460
Tmin_pos = MIN(P 0332, P 331) * P 0329 * P 0460
