CAUTION
Configure an electromagnetic brake circuit so that it is activated also by an external emergency stop switch.
When any alarm has occurred, eliminate its cause, ensure safety, and deactivate the alarm before
restarting operation.
If the molded-case circuit breaker or fuse is activated, be sure to remove the cause and secure safety
before switching the power on. If necessary, replace the servo amplifier and recheck the wiring.
Otherwise, it may cause smoke, fire, or an electric shock.
Provide an adequate protection to prevent unexpected restart after an instantaneous power failure.
To prevent an electric shock, injury, or fire from occurring after an earthquake or other natural disasters,
ensure safety by checking conditions, such as the installation, mounting, wiring, and equipment before
switching the power on.
(6) Maintenance, inspection and parts replacement
CAUTION
Make sure that the emergency stop circuit operates properly such that an operation can be stopped
immediately and a power is shut off by the emergency stop switch.
It is recommended that the servo amplifier be replaced every 10 years when it is used in general
environment.
When using a servo amplifier whose power has not been turned on for a long time, contact your local
sales office.
