CAUTION
(3) Trial operation and adjustment
Check and adjust each program and parameter before starting operation. Failure to do so could
lead to unforeseen operation of the machine.
Do not make remarkable adjustments and chang es as the operation could become unstable.
(4) Usage methods
Install an external emergency stop circu it so that the ope ration can be stopped and power
shut off immediately.
Turn the power OFF immediately if smoke, abnormal noise or odors are generated from the
servo drive unit or servomotor.
Unqualified persons must not disassemble or repair the unit.
Never make modifications.
Reduce magnetic damage by installing a noise filter. The electronic devices used near the
servo drive unit could be affected by magnetic noise.
Use the servo drive unit, servomotor and regenerative resistor with the designated combination.
Failure to do so could lead to fires or trouble.
The brake (magnetic brake) assembled into the servomotor is for holding, and must not be used
for normal braking.
There may be cases when holding is not possible due to the magnetic brake's life or the
machine construction (when ball screw and servomotor are coupled via a timing belt, etc.).
Install a stop device to ensure safety on the machine side.
After changing the programs/parameters or after maintenance and inspection, always test the
operation before starting actual operation.
Do not enter the movable range of the machine during automatic operation. Never place body
parts near or touch the spindle during rotation.
Follow the power supply specification conditions given in the separate specifications manual for
the power (input voltage, input frequency, tolerable sudden power failure time, etc.).
Set all bits to "0" if they are indicated as not used or empty in the explanation on the bits.
Do not use the dynamic brakes except during the emergency stop. Continued use of the
dynamic brakes could result in brake damage.
If a breaker is shared by several power supply units, the breaker may not activate when a
short-circuit fault occurs in a small capacity unit. This is dangerous, so never share the
breakers.

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.

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 ensu red 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.
