15.9 Power control (torque limitation)
The power control (torque limitation) generates a constant mass flow when
moving masses which change their specific weight, usually air exposed to
different temperatures.
Torque limit and speed setpoint are selected for the controller. The torque limit will
not be exceeded because the speed is automatically adapted if the specific
weight changes. The speed setpoint must be set in a way that it does not limit the
speed adaptation.
Control mode ”Sensorless torque control” (C0014 = 5):
With sensorless torque control, a constant torque is preselected. A defined speed
limit must not be exceeded (speed limitation).
