730 Torque Limit
731 Torque Limit Generator Operation
The output value of the speed controller is limited by an upper and a lower torque limit, parameter
Torque Limit 730 and parameter Torque Limit Generator Operation 731. The limit values are input
as a percentage of the rated motor torque. The assignment of fixed values or analog limit values is
done via the parameters
Torque Limit Source Motor Op. 736 and Torque Limit Source Gen. Op.

739 Power Limit
740 Power Limit Generator Operation
The power output by the motor is proportional to the product of speed and torque. This output power
can be limited at the speed controller output with
