(designated
pulse type
and pulse
resolution with
PULSE switch)
Pulse type
Select one of the following settings:
1. CCW + CW pulse train
2. Sign + pulse train
3. CCW + CW pulse train (negative logic)
4. Sign + pulse train (negative logic)
Pulse resolution
Select one of the following settings:
1. 1000 pulses/rev (open collector/line driver) 75 kpps max.
2. 2500 pulses/rev (open collector/line driver) 187.5 kpps max.

Clear input signal Clears the positioning error at the rising edge of the pulse
Servo ON input signal Turns the servo motor on or off
Alarm output signal OFF if an alarm occurs
Brake output signal External signal to control brakes. Turn ON to release the brake.
Position completed output signal ON if the current position is equal to the reference position ± 10 pulses
Origin output signal ON if the motor is at the origin (width: 1/500 rev)
Built-in functions
Dynamic brake (DB)
Operated at main power OFF, servo alarm, servo OFF
(OFF after motor stops; ON if the motor power is off)
Regenerative processing Optional (if the regenerative energy is too large, install a regenerative unit)

Be sure to use the motor within the allowable load moment of inertia. The motor will become unstable if the load moment of inertia exceeds the
allowable value.
*
2
The ground protection circuit is designed for ground fault inside the motor windings while the motor is running. Therefore, it may not protect the
system under the following cases:
• A low-resistance ground fault occurs in the main circuit cable or in the connector of the cable for the servo motor.
• The power supply is turned on during a ground fault.
