Basic Settings for Torque Control

This section describes the basic settings for torque control.
(1) Signal Setting
Set the following input signals.
Type
Input
Maximum input voltage: ±12 VDC
Input Circuit Example
Example
Pn400 = 0003.0: Motor rated torque at 3.0 V [Factory setting]
Note: The value is 30, but it will be displayed on the operator as 0003.0.
Speed Reference Input
Connect the pins for the T-REF signal and SG to the analog reference output terminal on the host controller
when using a host controller, such as a programmable controller, for torque control.
Note: Always use twisted-pair cables to control noise.
