CAUTION
(5) Troubleshooting
If a hazardous situation is predicted during power failure or product trouble, use a servomotor
with magnetic brakes or install an external brake mechanism.
Use a double circuit configuration
that allows the operation circuit for
the magnetic brakes to be operated
even by the external emergency
stop signal.

Servomotor
Shut off with the servomotor
brake control output.
Shut off with NC brake
control PLC output.
Always turn the input power OFF when an alarm occurs.
If an alarm occurs, remove the cause, and secure the safety before resetting the alarm.
Never go near the machine after restoring the power after a power failure, as the machine
could start suddenly. (Design the machine so that personal safety can be ensured even if the
machine starts suddenly.)
(6) Maintenance, inspection and part replacement
Always backup the programs and parameters before starting maintenance or inspections.
The capacity of the electrolytic capacitor will drop over time due to self-discharging, etc. To
prevent secondary disasters due to failures, replacing this part every five years when used
under a normal environment is recommended. Contact the Service Center, Service Station,
Sales Office or delayer for repairs or part replacement.
Do not perform a megger test (insulation resistance measurement) during inspections.
If the battery low warning is issued, back up the machining programs, tool data and
parameters with an input/output unit, and then replace the battery.
Do not short circuit, charge, overheat, incinerate or disassemble the battery.
The heat radiating fin used in some units contains substitute Freon as the refrigerant.Take
care not to damage the heat radiating fin during maintenance and replacement work.
(7) Disposal
Do not dispose of this type of unit as general industrial waste. Always contact the Service
Center, Service Station, Sales Office or delayer for repairs or part replacement.
Do not disassemble the unit or motor.
Dispose of the battery according to local laws.
Always return the secondary side (magnet side) of the linear servomotor to the Service
Center or Service Station.
When incinerating optical communication cable, hydrogen fluoride gas or hydrogen chloride
gas which is corrosive and harmful may be generated. For disposal of optical communication
cable, request for specialized industrial waste disposal services that has incineration facility
for disposing hydrogen fluoride gas or hydrogen chloride gas.
