4.7 Operation by Keypad
4.7.1 Parameter setting for keypad operation to rotate the motor at 100 rpm
① RUN/STOP command setting by keypad
② Operating speed reference setting by keypad
③ Operating speed setting
4.7.2 Forward / Reverse Run (FWD / REV)
① Low speed operation
z Check if motor speed is +100 rpm in the start-up LCD screen after pressing [FWD] key.
z Check if motor speed is –100 rpm in the start-up LCD screen after pressing [REV] key.
z The following table describes the cases of abnormal rotation due to the incorrect wiring of encoder
and/or motor.

RX Forward -100.0(rpm) Below -10%
Encoder and Motor
all reversed
z If A and B phase are reversed, be sure to replace A with B phase wire after checking the pulse
encoder wiring. Or user does not need to change wiring if PAR_11(Enc Dir Set) setting value is
changed from “A Phase Lead” to “B Phase Lead”.
z If Motor wires are reversed, be sure to replace V with W phase wire after checking the motor
output wiring.
z Torque display is on the basis of the no load operation.
