These signals are used when torque control is selected.
Servomotor torque is controlled so that it is proportional to the input
voltage between T-REF and SG.

Parameter Pn400 establishes the voltage level that applies rated torque.
For example:
With Pn400 = 30
Vin (V) Resulting Applied Torque
+3 100% of rated torque in forward direction
+9 300% of rated torque in forward direction
-0.3 10% of rated torque in reverse direction
