Instructions Manual
４－４．Setting PULSE INPUT TYPE SELECT switch
Erroneous setting may cause breakage of
the machine or injury due to unexpected
rotation of motor.
Ensure correct setting.
Pulse input method is set up with the SPI SEL switch.
Set this switch with power OFF.
(1) Turn power [OFF].
(2) Set the SPI SEL [2P/1P] switch.
● When the motor is operated with two pulse signal inputs of CW and CCW,
set the SPI SEL switch to [OFF(2P)].
● When the motor is operated with the pulse signal and direction signal
input, set the SPI SEL switch to [ON(1P)].
● In the case that 1-pulse input method is selected, the CCW terminal becomes
direction signal input designating the direction of the motor rotation.
Drive pulse set to the CW terminal(CW+,CW-).
● The input timing is same with 2-pulse input method and 1-pulse input method .
As for input timing, refer to "10-2. (2)Drive pulse input（CW, CCW)"
４－５．Setting ROTATE CHARACTRISTIC SELECT switch
Rotate character is set up with the ROTATE CHARACTRISTIC SEL
switch.
Set this switch with power OFF.
●When the division of the STEP SEL switch is 1/1 or 1/2,
by setting the R.C SEL switch to [OFF] the vibration of the motor
in a acceleration/deceleration drive may reduce.
