Turn the power off to validate changes in parameters No.0 and 1. Then switch power on again to make the
set parameter values valid.
(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) Start
Using speed selection 1 (SP1) and speed selection 2 (SP2), choose the servo motor speed. Turn on
forward rotation start (ST1) to run the motor in the forward rotation (CCW) direction or reverse rotation start
(ST2) to run it in the reverse rotation (CW) direction. At first, set a speed as low as 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, load factor, etc. of the servo motor.
When machine operation check is over, check automatic operation with the host controller or the like.
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) 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 simultaneous ON
or simultaneous OFF of forward rotation stroke end (LSP), reverse rotation stroke end (LSN) OFF and
forward rotation start (ST1) or reverse rotation start (ST2) has the same stop pattern 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.
