(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 dealer for repairs
or part replacement.
Never perform a megger test (measure the insulation resistance) of the drive unit. Failure to observe this
could lead to faults.
If the battery low warning is issued, immediately replace the battery. Replace the batteries while applying the
drive unit's control power.
Do not short circuit, charge, overheat, incinerate or disassemble the battery.
For after-purchase servicing of the built-in motor, only the servicing parts for MITSUBISHI encoder can be
supplied. For the motor body, prepare the spare parts at the machine tool builders.
For maintenance, part replacement, and services in case of failures in the built-in motor (including the
encoder), take necessary actions at the machine tool builders. For drive unit, Mitsubishi can offer the after-
purchase servicing as with the general drive unit.
(7) Disposal
Take the batteries and backlights for LCD, etc., off from the controller, drive unit and motor, and dispose of
them as industrial wastes.
Do not disassemble the unit or motor.
Dispose of the battery according to local laws.
Dispose of the primary side of the linear servo motor as industrial waste. For the secondary side, dispose of
it as industrial waste after demagnetizing it by heating it to 300°C or higher.
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.
