During power-on, do not open or close the motor power line. Otherwise, a
malfunction or faulty may occur.
Note:1. To prevent an electric shock, always connect the protective earth (PE) terminal of the
servo amplifier to the protective earth (PE) of the control box.
2. This circuit applies to the servo motor with electromagnetic brake.
3. For the HA-FF series, connect the ground cable to the earth terminal of the servo
motor.
Note:1.To prevent an electric shock, always connect the protective earth (PE) terminal of the
servo amplifier to the protective earth (PE) of the control box.
