(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.
Always turn the main circuit power of the motor OFF
when an alarm occurs.
If an alarm occurs, remove the cause, and secure the
safety before resetting the alarm.
(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.
For after-purchase servicing of the built-in motor (including the detector), supplies of servicing parts and
repairs can only be offered.
For maintenance, part replacement, and services in case of failures in the built-in motor (including the
detector), take necessary actions at your end. For spindle drive unit, Mitsubishi can offer the after-
purchase servicing as with the general spindle drive unit.
When a failure has occurred in the built-in motor (including the detector), some period of time can be
required to supply the servicing parts or repair. Prepare the spare parts at your end whenever possible.
(7) Disposal
Take the batteries and backlights for LCD, etc., off from the controller, drive unit and motor, and dispose
of them as general industrial wastes.
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.
