Input Signals
Torque Reference Inputs
The following input signals are used for torque control.
ð Input T-REF CN1-9
ð Input SG CN1-10
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:
T-REF
Torque reference input
SG
(Analog voltage input)
V-REF
Speed reference input
SG
(Analog voltage input)
P represents twisted pair wires
