Input Circuit Example
• 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.
Adjust Pn300 according to the output voltage specifications of the host controller.
Adjust the speed reference input adjustment factor at the following parameter.
Set the voltage range for the speed reference input V-REF at CN1-5 according to
host controller and external circuit output range.
The default setting is adjusted so that a 6V 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 ± 12V
