Torque Control
This function can be used in torque control, as well as in the speed and pulse train position controls.
Torque control can be applied to winders, and more.
To run the Inverter in torque control mode, allocate “52” (ATR) to any of the multi-function inputs.
While the ATR terminal is turned on, the torque reference input is enabled.
With torque reference input selection P033, you can select either each analog input or the input via
the Digital Operator.
The torque control speed depends on the balance between torque and load. To prevent the Inverter
from running out of control, set a speed limit value in P039 (forward) or P040 (reverse).
Parameter No.
