Input Circuit Example
+12V
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 in the following
parameter.
Parameter
Pn300
Set the voltage range for the V-REF speed reference input at CN1-5
according to the 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
470 Ω, 1/2W min.
