Input circuit configurationʢCW and CCW Pulse inputʣ
• Pulse duty : 50 % MAX.
• When the crest value of the input signal is 5 V, the external limit resistance R must
be 0 Њ . When the crest value of the input signal exceeds 5 V, use the external limit
resistance R to limit the input current to approximately 15 mA.

˙ Timing of the command pulse
• The internal photo coupler turns ON within the ˙
and, when the DIP switch lCz = lOFFz , the internal
circuitʢstepping motorʣoperates at the rising edge
of lONz of the photo coupler.
• When applying the pulse to CW, turn OFF the CCW
side internal photo coupler.
• When applying the pulse to CCW, turn OFF the CW
side internal photo coupler.
• When the DIP switch lCz = lONz , the internal circuit
ʢstepping motorʣoperates at the rising edge and
falling edge of lONz of the photo coupler.
