Function
Inputs the drive pulse for the rotation in the CW direction.
Inputs the drive pulse for the rotation in the CCW direction.
Inputting the PD signal turns off the current that flows through the stepping motor.
Photo coupler input method : Internal photo coupler ONʜʜ PD function enabled
Indicates ON when the exciting phase is at the origin position.
In the full-step, outputs once for every 6 pulses.
˔ The CW direction of the rotation of the stepping motor is the clockwise direction when viewing the stepping motor from the output axis sideʢflange sideʣ.
The CCW direction is the counterclockwise direction when viewing the stepping motor from the output axis sideʢflange sideʣ.

the source of the PM driver.
1 SLʢauto current down selectionʣ
Select the auto current down function.
SL
Automatic current reduction
ON
100 % of current rating when stopped
OFF Approx. 50 % of current rating when stopped
Note 1Ê£The temperature increase in the
motor driver can be controlled
by setting SL to OFFÊ¢approx. 50 %
of the rated currentʣ.
Note 2Ê£The output torque when SL is OFF
ʢapprox. 50 % of the rated currentʣ
is approx. 50 % of that when SL is
ONʢ100 % of the rated currentʣ.

ŋ When the DIP switch lCz = lONzʢ1/16 divisionʣ, the internal circuitʢstepping motorʣ
operates at the rising edge and falling edge of the drive pulse. If the duty ratio of the
drive pulse moves out of the adjustment significantly by 50 %, operation becomes
unstable.
