CW pulse signal
(Pulse signal)
CW direction motion command pulse signal (For 1-pulse input type, motion
command pulse signal) Pulse width 5ms or more, rise and fall time 2ms or
less, activated by pulse fall (Negative logic pulse input)
CCW pulse signal
(Rotating direction signal)
CCW direction motion command pulse signal
(For 1-pulse input type, rotational direction pulse signal H:CCW.L: CW)
Pulse width 5ms or more, rise and fall time 2ms or less, activated by pulse fall
(Negative logic pulse input)
Output current off signal
At the “L” level, the output current to the motor becomes off, and the motor
shaft can be rotated by an external force.
At the “H” level, the operation current specified with the (RUN) switch is
supplied to the motor.

conditions DC 24V or less, 10mA or less
Excitation timing signal
Signal is output when excitation sequence is at Step “0.” (Photo coupler ON)
When in full step: One output per 10 pulses.
When in half step: One output per 20 pulses
Overheat signal
Output when internal driver temperature
(Photo coupler ON or OFF, automatic negative return)
Motor turned OFF by auto hold off function.
