2. INSTALLATION AND START UP
2.7 Start up
WARNING
Do not operate the switches with wet hands. You may get an electric shock.
Do not operate the controller with the front cover removed. High-voltage terminals
and charging area exposed and you may get an electric shock.
During power-on or operation, do not open the front cover. You may get an electric
shock.
CAUTION
Before starting operation, check the parameters. Some machines may perform
unexpected operation.
Take safety measures, e.g. provide covers, to prevent accidental contact of hands
and parts (cables, etc.) with the servo amplifier heat sink, regenerative brake
resistor, servo motor, etc.since they may be hot while power is on or for some time
after power-off. Their temperatures may be high and you may get burnt or a parts
may damaged.
During operation, never touch the rotating parts of the servo motor. Doing so can
cause injury.
Connect the servo motor with a machine after confirming that the servo motor operates properly alone.
(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.
