It is turned ON when the excitation phase is at the
origin（in the state when the power is turned ON）
It is turned ON once per 4 pulses when setting to
HALF step.
It is turned ON once per 8 pulses when setting to
FULL step.
Alarm output 9
10
The signal is externally output when one of several
alarm circuits operates in the PM driver. At this time,
the stepping motor is in the unexcited state.
■ Specification summary of CN1 I/O signal
The CW rotation direction of stepping motor means the clockwise direction rotation as
viewed from the output shaft side（flange side）. The CCW rotation direction means the
counterclockwise direction rotation as viewed from the output shaft side（flange side）.

3 LED for power supply monitor（POW）
Lit up when the main circuit power
supply is connected.
Indicator Explanation
..ALM.. is
displayed.
Motor cable is broken, or switching element in
driver is faulty. The main circuit voltage is out
of specifications range (Less than DC19V).
When ..ALM.. is displayed, the winding current of the stepping
motor is cut off and it is in a ..non-excitation.. state. At the same
time, an output signal is transmitted from the alarm output
terminal (AL) to an external source. When the alarm circuit is
operating, this state is maintained until it is reset by switching on
the power supply again. When an alarm condition has occurred,
please take corrective actions to rectify the cause of the alarm
before switching on the power supply again.
