Torque limiting

The value specifies the maximum permissible torque whereby different limits can be

parameterized for motor and regenerative mode.

The currently active torque limit values are displayed in the following parameters:

All of the following limits act on the torque setpoint – that is either available at the speed

controller output for closed-loop speed control or as torque input, for closed-loop torque

control. The minimum or the maximum is used for the various limits. This minimum or

maximum is cyclically calculated and is displayed in r1538 or r1539.
