(6) Usage methods
Immediately turn OFF the power if smoke, abnormal sounds or odors are emitted from the Motion
controller, servo amplifier or servomotor.
Always execute a test operation before starting actual operations after the program or parameters
have been changed or after maintenance and inspection.
Do not attempt to disassemble and repair the units excluding a qualified technician whom our
company recognized.
Do not make any modifications to the unit.
Keep the effect or electromagnetic obstacles to a minimum by installing a noise filter or by using
wire shields, etc. Electromagnetic obstacles may affect the electronic devices used near the
Motion controller or servo amplifier.
When using the CE Mark-compliant equipment, refer to this manual for the Motion controllers and
refer to the corresponding EMC guideline information for the servo amplifiers, inverters and other
equipment.
Use the units with the following conditions.
Input power
Input frequency
Tolerable momentary power failure
(7) Corrective actions for errors
If an error occurs in the self diagnosis of the Motion controller 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 electromagnetic brakes 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.)
