Timing of command pulse
Input circuit confi guration of CW (CK), CCW (U/D)
• The shaded regions in the diagram indicate when the internal photocoupler
is ON. The internal circuit (motor) is ac tive at the rising edge of the
photocoupler pulses.
• To apply pulse to CW, set CCW side internal photo coupler to OFF .
• To apply pulse to CCW, set CW side internal photo coupler to OFF .
• The shaded regions in the diagram indicate when the internal photocoupler
is ON. The internal circuit (motor) is active at the rising edge of the CK-side
photocoupler pulses.
• Switching of U/D input signal must be done while CK side internal photo
coupler is OFF .

• Pulse duty 50% MAX.
• Maximum input frequency: 250kpulse/s
• When the crest value of the input signal exceeds 5V,
• use the external limit resistance R to limit the input current to approximately
15mA.
