Troubleshooting Precautions
Wait for at least six minutes after turning OFF the power supply
(with a SERVOPACK for a 100-VAC power supply input, wait for
at least nine minutes) and then make sure that the CHARGE indi-
cator is not lit before starting wiring or inspection work. Do not
touch the power supply terminals while the CHARGE lamp is lit
after turning OFF the power supply because high voltage may still
remain in the SERVOPACK.
There is a risk of electric shock.
Before you replace a SERVOPACK, back up the settings of the
SERVOPACK parameters. Copy the backed up parameter set-
tings to the new SERVOPACK and confirm that they were copied
correctly.
If you do not copy backed up parameter settings or if the copy
operation is not completed normally, normal operation may not be
possible, possibly resulting in machine or equipment damage.
Discharge all static electricity from your body before you operate
any of the buttons or switches inside the front cover of the SER-
VOPACK.
There is a risk of equipment damage.
If the safety device (molded-case circuit breaker or fuse) installed
in the power supply line operates, remove the cause before you
supply power to the SERVOPACK again. If necessary, repair or
replace the SERVOPACK, check the wiring, and remove the factor
that caused the safety device to operate.
There is a risk of fire, electric shock, or injury.
The product may suddenly start to operate when the power sup-
ply is recovered after a momentary power interruption. Design the
machine to ensure human safety when operation restarts.
There is a risk of injury.
