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.
MBR
24VDC
EMG
Magnetic
brake
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.
Never go near the machine after restorin g the power after a power failure, as the machine
could start suddenly. (Desi gn the machine so that personal safety can be ensured even if the
machine starts suddenly.)
(6) Maintenance, inspection and part replacement
Always carry out maintenance and in spection after backing up the servo drive unit's prog rams
or parameters.
The capacity of the electrolytic capacitor will drop over time. 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 or Service Station for replacement.
Do not perform a megger test (insulatio n resistance measurement) during inspection s.
If the battery low warning is issued, save 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 d isassemble the battery.
(7) Disposal
Treat this unit as general industrial waste . Note that MDS Series unit with a heat dissipating
fin protruding from the back of the unit contains substitute Freon. Do not dispose of this type
of unit as general industrial waste. Always return to the Service Center or Service Station.
Do not disassemble the servo drive unit or servomoto r parts.
Dispose of the battery according to local laws.
(8) General precautions
The drawings given in this Specifications and Maintenance Instruction Manual show the covers and
safety partitions, etc., removed to provide a clearer explanation. Always return the covers or partitions to
their respective places before starting operation, and always follow the instructions given in this manual.
