Always use twisted pair cable for noise control.
Recommended variable resistor: Model 25HP-10B manufactured by Sakae
Tsushin Kogyo Co., Ltd.
Connect V-REF and SG to the speed reference output terminals on the host
controller when using a host controller, such as a programmable controller,
for position control.

The default setting is adjusted so that a 6 V input is equivalent to the rated
motor speed of all applicable servomotors.

Note: The maximum allowable voltage to the speed reference input (between CN1-5 and 6) is ± 12 VDC.
