4. OPERATION
4.2.3 Internal speed control mode
(1) Power on
1) Switch off the servo-on (SON) signal.
2) When circuit power is switched on, the display shows "r (servo motor speed)", and in two second
later, shows data.
(2) Test operation
Using jog operation in the test operation mode, make sure that the servo motor operates. (Refer to
Section 6.8.2.)

(3) Parameter setting
Set the parameters according to the structure and specifications of the machine. Refer to Chapter 5 for
the parameter definitions and to Sections 6.5 for the setting method.

Turn the power off after setting 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 circuit power supply.
2) Switch on the servo-on signal (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 low speed 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)
