Functions/Applications
Forced stop EMG When EMG-SG are opened, the servo amplifier is placed in the forced stop status,
the servo switches off, and the dynamic brake is operated to bring the servo motor
to a sudden stop.
Short EMG-SG in the forced stop status to cancel the forced stop status.
Servo-on SON CN1B
15
Connect SON-SG to switch on the base circuit and make the servo amplifier ready
to operate (servo-on).
Disconnect SON-SG to shut off the base circuit and coast the servo motor (servo-
off) .
Reset RES Disconnect RES-SG for more than 50ms to reset the alarm.
Some alarms cannot be deactivated by the reset signal. Refer to section 11.2.1
If RES-SG are shorted in no alarm status, the base circuit is not shut off.
Set "
1 " in parameter No. 55 to shut off the base circuit.
Since this device is not designed for stopping. Do not switch it on during operation.
