For p1400.4 = 1, the first torque limit applies for motoring operation and the other for regenerative operation, independently of the sign of the torque
and the speed (compatible with SIMODRIVE).
"Normal case":
If neither dynamic limits nor offsets are required, the torque limit when motoring is entered via p1520. The torque limit when
regenerating is entered via p1521 (as a negative value).
For the manufacturer-specific PROFIdrive telegrams 102 und 103, r1543 is entered here [5610.4].<2>
<3> With p1400.13 = 0, the following applies: if n_act < p1546, the motor limit is effective.
With p1400.13 = 1, the following applies: if n_set = 0, the regenerative limit is effective.
