Siemens SINAMICS G110M - Torque Control

8.19.3 Torque control
Overview
Torque control is part of the vector control and normally receives its setpoint from the speed
controller output. By deactivating the speed controller and directly entering the torque setpoint,
the closed-loop speed control becomes closed-loop torque control. The converter then no
longer controls the motor speed, but the torque that the motor generates.

Function description
Typical applications for torque control
The torque control is used in applications where the motor speed is speci󹪝ed by the connected
driven load. Examples of such applications include:
• Load distribution between master and slave drives:
The master drive is speed controlled, the slave drive is torque controlled.
• Winding machines
The most important settings
Preconditions for the correct functioning of the torque control:
• You have set the motor data correctly during the quick commissioning
Quick commissioning (Page 106)
• You have performed a motor data identi󹪝cation on the cold motor
Advanced commissioning
