(5) Corrective actions
When it is assumed that a hazardous condition may take place at the occur due to a power
failure or a product fault,, use a servo motor with electromag<->netic brake or an external
brake mechanism for the purpose of prevention.
Configure the electromagnetic brake circuit so that it is activated not only by the servo
amplifier signals but also by an external emergency stop signal.
When any alarm has occurred,, eliminate its cause,, ensure safety,, then reset the alarm,,
before restarting operation.
When power is restored after an instantaneous power failure,, keep away from the ma-
chine because the machine may be restarted suddenly (design the machine so that it is
secured against hazard if restarted).
(6) Maintenance, inspection and parts replacement
With age, the electrolytic capacitor will deteriorate. To prevent a secondary accident due
to a fault, it is recommended to replace the electrolytic capacitor every 10 years when
used in general environment.
Please consult our sales representative.
