(h) Stop
In any of the following statuses, the servo amplifier interrupts and stops the operation of the servo
motor.
When the servo motor used is equipped with an electromagnetic brake, refer to section 3.9 (3). Note
that forward rotation stroke end (LSP), reverse rotation stroke end (LSN) off has the same
stopping pattern as described below.
1) Servo-on (SON) OFF
The base circuit is shut off and the servo motor coasts.
2) Alarm occurrence
When an alarm occurs, the base circuit is shut off and the dynamic brake is operated to bring the
servo motor to a sudden stop.
3) Forced stop (EMG) OFF
The base circuit is shut off and the dynamic brake is operated to bring the servo motor to a
sudden stop. Servo forced warning (AL.E6) occurs.
4) Forward rotation stroke end (LSP), reverse rotation stroke end (LSN) OFF
The droop pulse value is erased and the servo motor is stopped and servo-locked. It can be run in
the opposite direction.
