(7) Corrective actions for errors
If an error occurs in the self diagnosis of the module or servo amplifier, confirm the check details
according to the instruction manual, and restore the operation.
If a dangerous state is predicted in case of a power failure or product failure, use a servomotor
with an electromagnetic brake or install a brake mechanism externally.
Use a double circuit construction so that the electromagnetic brake operation circuit can be
operated by emergency stop signals set externally.
If an error occurs, remove the cause, secure the safety and then resume operation after alarm
release.
The unit may suddenly resume operation after a power failure is restored, so do not go near the
machine. (Design the machine so that personal safety can be ensured even if the machine
restarts suddenly.)
