4. OPERATION
(4) Servo-on
Switch the servo-on in the following procedure.
1) Switch on power supply.
2) Switch on the servo-on (SON).
When placed in the servo-on status, the servo amplifier is ready to operate and the servo motor is
locked.
(5) Command pulse input
Entry of a pulse train from the positioning device rotates the servo motor. At first, run it at lowest speed
possible and check the rotation direction, etc. If it does not run in the intended direction, check the input
signal.

On the status display, check the speed, command pulse frequency, load factor, etc. of the servo motor.
When machine operation check is over, check automatic operation with the program of the positioning
device.
This servo amplifier has a real-time auto tuning function under model adaptive control. Performing
operation automatically adjusts gains. The optimum tuning results are provided by setting the response
level appropriate for the machine in parameter No.2. (Refer to chapter 7)
(6) Home position return
Make home position return as required.
(7) Stop
In any of the following statuses, the servo amplifier interrupts and stops the operation of the servo motor.
Refer to section 3.9 for the servo motor equipped with electromagnetic brake. Note that the stop pattern of
forward rotation stroke end (LSP), reverse rotation stroke end (LSN) OFF is as described below.
(a) Servo-on (SON) OFF
The base circuit is shut off and the servo motor coasts.
(b) 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.
(c) Emergency stop (EMG) OFF
The base circuit is shut off and the dynamic brake is operated to bring the servo motor to a sudden stop.
Alarm AL.E6 (servo emergency stop warning) occurs.
(d) 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.
