Input signals
The signal state represents the “ON: Carrying current” or “OFF: Not carrying
current” state of the internal photocoupler.

PLS (pulse) input, DIR (rotating direction) input
Either 5 or 24 VDC can be used as the signal voltage for the PLS input, and DIR
input.
Line driver input is also supported.
5 VDC
The controller pulses are connected to the PLS+ input (pin No.1) or the PLS ! input
(pin No.9), and the rotation direction is connected to the DIR+ input (pin No.3) or
DIR
! input (pin No.11).
!"
When the DIR input is ON, a fall of the PLS input from ON to OFF will rotate the
motor one step in the CW direction.
!"
When the DIR input is OFF, a fall of the PLS input from ON to OFF will rotate
the motor one step in the CCW direction.

Note The interval for switching the motor direction represents the response time
of the circuit. Set this interval to an appropriate time after which the motor
will respond.
