Servo-on SON CN1B
5Ready signal input terminal.
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) .
Set1 in parameter No. 41 to switch this signal on
(keep terminals connected) automatically in the servo
amplifier.

Reset RES CN1B
14 Alarm reset signal input terminal.
Disconnect RES-SG for more than 50ms to reset the alarm.
Some alarms cannot be deactivated by the reset signal. Refer to
Section 9.2.
The base circuit is shut off while RES-SG are shorted.

To start operation, short LSP-SG and/or LSN-SG. Open them to
bring the motor to a sudden stop and make it servo-locked.
Set1 in parameter No. 22 to make a slow stop.
