Troubleshooting Precautions
D

NGER
Do not change any wiring while power is being supplied.
There is a risk of electric shock or injury.

RNING
Wiring and inspections must be performed only by qualified engineers.
There is a risk of electric shock or product failure.
If you replace a Linear Servomotor, secure the machine before you replace the Servomotor.
There is a risk of injury or equipment damage if the equipment falls.

UTION
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
indicator is not lit before starting wiring or inspection work. Do not touch the power supply ter-
minals while the CHARGE lamp is lit because high voltage may still remain in the SERVOPACK
even after turning OFF the power supply.
There is a risk of electric shock.

RNING
The product may suddenly start to operate when the power supply is recovered after a momen-
tary power interruption. Design the machine to ensure human safety when operation restarts.
There is a risk of injury.

UTION
When an alarm occurs, remove the cause of the alarm and ensure safety. Then reset the alarm
or turn the power supply OFF and ON again to restart operation.
There is a risk of injury or machine damage.
If the Servo ON signal is input to the SERVOPACK and an alarm is reset, the Servomotor may
suddenly restart operation. Confirm that the servo is OFF and ensure safety before you reset an
alarm.
There is a risk of injury or machine damage.
If there is the possibility that an external force (including gravity) may move the current position
and create a hazardous situation when power is interrupted or an error occurs, install an exter-
nal braking mechanism that ensures safety.
