J Example of Input Circuit
(See the figure on the right)
For noise control, always use twisted-pair
cables.
Recommended Variable Resistor for Speed Setting:
Type 25HP-10B manufactured by Sakae Tsushin Kogyo Co., Ltd.
When position control is performed by a host con-
troller such as a programmable controller, con-
nect V-REF and SG to speed reference output ter-
minals on the host controller. In this case, adjust
Cn-03 according to output voltage specifications.
The internal ¦12 V power supply can be used.

Speed Control
This is normal speed control.
• Speed reference is input from V-REF (1CN-5).
• /P-CON (1CN-41) signal is used to switch
between P control and PI control.
