2. INSTALLATION AND START UP
(1) Power on
Switching on the main circuit power/control circuit power places the interface unit display in the scroll
status as shown below.
In the absolute position detection system, first power-on results in the absolute position lost (A.25)
alarm and the servo system cannot be switched on. This is not a failure and takes place due to the
uncharged capacitor in the encoder.
The alarm can be deactivated by keeping power on for a few minutes in the alarm status and then
switching power off once and on again.
Also in the absolute position detection system, if power is switched on at the servo motor speed of
500r/min or higher, position mismatch may occur due to external force or the like. Power must
therefore be switched on when the servo motor is at a stop.
(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.
After setting the parameters, switch power off once.
