• 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.
• The product may suddenly start to operate when the power supply is recovered
after a momentary power interruption. Design the machine to ensure human
safety when operation restarts.
• 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 opera-
tion.
• 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.
• Always insert a magnetic contactor in the line between the main circuit power
supply and the main circuit power supply terminals on the SERVOPACK so
that the power supply can be shut OFF at the main circuit power supply.
• If an alarm occurs, shut OFF the main circuit power supply.
• Install a ground fault detector against overloads and short-circuiting or install
a molded-case circuit breaker combined with a ground fault detector.
• The holding brake on a Servomotor will not ensure safety if there is the possi-
bility that an external force (including gravity) may move the current position
and create a hazardous situation when power is interrupted or an error occurs.
If an external force may cause movement, install an external braking mecha-
nism that ensures safety.
• When disposing of the product, treat it as ordinary industrial waste. However,
local ordinances and national laws must be observed. Implement all labeling
and warnings as a final product as required.

Troubleshooting Precautions
Disposal Precautions
DANGER
There is a risk of fire, electric shock, or injury.
WARNING
There is a risk of injury.
CAUTION
There is a risk of injury or machine damage.
There is a risk of injury or machine damage.
If a magnetic contactor is not connected when the SERVOPACK fails, a large
current may flow, possibly resulting in fire.
There is a risk of fire due to a regenerative resistor overheating as the result of
regenerative transistor failure.
There is a risk of SERVOPACK failure or fire if a ground fault occurs.
