 Input Signals
Torque Reference Inputs
The following input signals are used for torque control.
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.
 Default Settings
Parameter Pn400 establishes the voltage level that applies rated torque.
For example:
Input T-REF CN1-9 Torque Reference Input Speed/Torque Control
Input SG CN1-10
Signal Ground for the Torque
