6 Connection
2-pulse input mode
The controller's CW pulses are connected to the CW+ or the CW−, while the CCW
pulses are connected to the CCW+ or the CCW−.
• When the CW pulse input changes from the ON to OFF, the motor will rotate one
step in the CW direction.
• When the CCW pulse input changes from the ON to OFF, the motor will rotate
one step in the CCW direction.
Use an input pulse signal with a waveform having a sharp rise and fall, as shown in
the figure:

The interval for switching the motor direction represents the response
Note
•
time of the circuit. Set this interval to an appropriate time after which the
motor will respond.
Always set the photocoupler to OFF when not inputting pulse signals.
•
Do not input CW pulse input and CCW pulse input at the same time. If
•
one of these pulses is input when the other is ON the motor will not run
properly.
• AWO (All windings off) input
Use the signal only when the motor's output shaft must be rotated manually for
position adjustment (ON: 4.5 to 5 V, OFF: 0 to 1 V.)
• When the AWO input is turned ON, the driver stops supplying current to the
motor and the motor's holding torque is lost. You to adjust the load position
manually.
• When the AWO input is turned OFF, the current supply to the motor resumes,
thereby restoring the motor's holding torque.
