4. OPERATION
4.2.3 Internal speed control mode
(1) Power on
1) Switch off the servo-on (SON).
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 section 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 (SON) signal. (Short between SON and VIN.)
When placed in the servo-on status, the servo amplifier is ready to operate and the servo motor is
locked.
