Torque control
7.9.3.
Speed limiting
The setpoint speed after the ramp generator (ru.02) serves for speed limiting.
The setpoint speed is formed (with exception of the rotation direction) in the same manner as in speed-con-
trolled operation or open-loop operation. The direction of rotation results from the sign of the torque reference.
Without limiting the speed, the drive would accelerate to indefinitely high speeds if the counter torque disap
-
pears.
Since the limiting is based on the speed at the ramp generator output, the acceleration/ deceleration ramps
should be set to 0 s for this operating mode.
7.9.4.
Control mode
There are 2 different modes for torque-controlled operation. They can be selected by cS.00 = 5 or cS.00 = 6 .
7.9.4.1
Mode 1: Torque-controlled operation with emergency changeover to speed control
This mode is activated with cS.00 = 5.
The speed controller is not active until the drive does not exceed the maximum speed for torque-controlled
operation (= set speed ru.02) .
This has the advantage that the parameterization of the speed controller has no influence to the set torque.
The change to speed-controlled operation occurs only when the speed limit is reached. Caused by the change-
over the control characteristic is not optimal here. Overshoots can occur.
