4.7.2 Torque Reference Input

By applying a torque reference determined by the analog voltage reference to the servo drive, the servomotor torque can
be controlled in proportion with the input voltage.

Used during torque control (analog voltage reference)
(Pn005.1=2，6，8，9)
The torque reference input gain is set in Pn400. For setting
details, refer to 4.7.1 Setting Parameters.
■Input specifications
· Input range:DC±0～±10V/rated torque
· Factory setting
Pn400=30：Rated torque at 3V
+3V input：Rated torque in forward direction
+9V input：300% rated torque in forward direction
-0.3V input：10% rated torque in reverse direction
The voltage input range can be changed with parameter Pn400.
■Input circuit example
Use twisted-pair wires as a countermeasure against noise.
■Checking the internal torque reference
1.Checking the internal torque reference with the panel operator.
Use the Monitor Mode(Un003). Refer to 5.1.6 Operation in Monitor Mode.
2.Checking the internal torque reference with an analog monitor.
The internal torque reference can also be checked with an analog monitor.
