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.
• Factory Settings
Pn400 = 30: This setting means that 3 V is equivalent to the rated torque.
+3 V input: Rated torque in the forward direction
+9 V input: 300% of rated torque in the forward direction
-0.3 V input: 10% of rated torque in the reverse direction
Parameter Pn400 can be used to change the voltage input range.
• Example of an Input Circuit
Always use twisted-pair cable for noise control.
Recommended variable resistor: Model 25HP-10B manufactured by Sakae Tsushin
Kogyo Co., Ltd.
