„ Setting Examples
Pn300 = 600: This setting means that 6 V is equivalent to the rated motor speed.
Parameter Pn300 can be used to change the voltage input range.
„ 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 output voltage specifications.
Adjust the speed reference input gain at the following parameter.
