12.10 Torque follower
This basic function is used as setpoint interface for torque-controlled drives.
• The motor control is switched over automatically to torque control with speed limitation.
• If the direction of rotation of the motor has to be inverted due to the mounting position of the
motor or the gearbox ratio available, the use of the control signals can be accordingly changed
over by means of parameterisation.
• A stable speed limitation requires a minimum difference of the speed limit values of 50 rpm. If
the defined speed limit values fall below this minimum difference, the internal lower speed
limit value is lowered accordingly. The upper speed limit value remains unchanged.  Signal

The following applies to the encoderless motor control types :
The basic function "Torque follower" cannot be activated when the V/f control has been
selected.
