  • Page 22: About Input/Output Signals

    6 Connection 6.6 About input/output signals Input signals All input signals of the driver are photocoupler inputs. The signal state represents the “ON: Carrying current” or “OFF: Not carrying current” state of the internal photocoupler rather than the voltage level of the signal. 5 VDC can be directly connected.
  • Page 23 6 Connection 1-pulse input mode Connect the controller pulse to Pin No.2 “−PLS input” and the rotating direction to Pin No.4 “−DIR input.” • 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.
  • Page 24 6 Connection • C.OFF (All windings off) input Use this signal when the motor’s output shaft must be mechanically rotated for position adjustment. Warning Do not turn the C.OFF input to “ON” while the motor is operating. The motor will stop and lose its holding ability.
  • Page 25 6 Connection Output signals All output signals of the driver are photocoupler/open-collector outputs. The signal state represents the “ON: Carrying current” or “OFF: Not carrying current” state of the internal photocoupler rather than the voltage level of the signal. Use output signals with a power supply not exceeding 24 VDC and 10 mA. Note If these specifications are exceeded, the internal elements may be damaged.
  • Page 26 6 Connection Example of TIM output not turning “ON” The figure below shows a condition in which the motor operates for a period of nine pulses at a step angle of 0.072°/step, and then operates for one pulse at a step angle of 0.72°/step. The TIM output will not switch to “ON”...
  • Page 27: Timing Chart

    6 Connection Motor operation is continued Set the A.C.O. function select switch to “OFF: Automatic current off disable”. The O.H. output is turned “OFF” when the driver’s internal temperature reaches approx. 80 °C (176 °F). Output current remains on and the motor continues to operate. Then the electromagnetic brake is not actuated.
