Input signal for reference
Designated pulse type and
pulse resolution with PULSE
switch.
Pulse type
Select one of the following signals:
1. CCW + CW
2. Sign + pulse train
3. CCW + CW (logic reversal)
4. Sign + pulse train (logic reversal)
Pulse resolution
Select one of the following signals:
1. 1000 pulses/rev (Open collector/line driver) 75 kpps max.
2. 2500 pulses/rev (Open collector/line driver) 187.5 kpps max.
3. 5000 pulses/rev (Line driver) 375 kpps max.
4. 10000 pulses/rev (Line driver) 750 kpps max.
Clear input signal
Clears the positioning error when turned ON
Servo ON input signal
Turns the servomotor ON or OFF
Alarm output signal
OFF if an alarm occurs. (Note: OFF for 2s when power is turned ON)
Brake output signal
External signal to control brakes. Turn ON to release the brake
Positioning completed output signal
ON if the current position is equal to the reference position
±
10 pulses.External signal to control brakes.
Origin output signal
ON if the motor is at the origin. (Width: 1/500 rev)
(Note:Use the pulse edge that changes the signal from OFF to ON)
