Procedures before Operation
4.2.1
Start up procedure
Power on
When the main and control circuit power supplies are switched on, "d1" (for the first axis)
appears on the servo amplifier display.
In the absolute position detection system, first power-on results in the absolute position lost (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.
Parameter setting
Set the parameters according to the structure and specifications of the machine.
After setting the above parameters, switch power off once. Then switch power on again to make
the set parameter values valid.

DANGER:
●
Do not operate the switches with wet hands. You may get an electric shock.
●
Do not operate the controller with the front cover removed. There is the risk of
getting an electric shock from live parts.
●
During power-on or operation, do not open the front cover. You may get an electric
shock.
●
Before starting operation, check the parameters. Through the incorrect setting of
parameters some machines may execute unexpected movements.
●
Never touch the cooling fins of the servo amplifier, the brake resistor, servo motor
or other components while the power supply is still on or shortly after switching it
off. They can become very hot and touching them could result in serious burns.
