Torque control

Overview
Torque control is part of the speed control and is used when the speed controller has been
disabled.
Requirement
• You have set the motor data correctly during quick commissioning.
The motor data is transferred from the nameplate and calculated with the motor data
identification during quick commissioning.
• You have performed a motor data identification on the cold motor.
Description of function
Figure 14-152 Simplified function diagram of the closed-loop torque control
The torque control normally receives its setpoint from the output of the speed controller. By
disabling the speed controller and directly setting the torque setpoint, the closed-loop speed
control becomes a closed-loop torque control. The converter then no longer controls the
speed of the motor, but instead the torque that the motor generates.
