CAUTION
Do not alter.
Use a noise filter, etc. to reduce the effect of electromagnetic disturbances. Electromagnetic
disturbances could adversely affect the electronic devices used near the servo drive unit.
Use the servo drive unit, servomotor and each regenerative resistor with the designated
combination. Failure to observe this could result in fires or faults.
The combination of the servomotor and servo drive unit that can be used is determined. Be sure to
check the models of servomotor and servo drive unit before test operation.
The brakes (electromagnetic brakes) mounted in the servomotor are used for the purpose of
holding, and must not be used for normal braking. Also, do not run the motor with the motor brake
applied. Motor brake is used for the purpose of holding.
For the system running via a timing belt, install a brake on the machine side so that safety can be
ensured.
Be sure to confirm SERVO OFF (or READY OFF) when applying the magnetic brake. Also, be sure
to confirm SERVO ON prior to releasing the brake.
When using the DC OFF type electromagnetic brake, be sure to install a surge absorber on the
brake terminal.
Do not connect or disconnect the cannon plug while the electromagnetic brake’s power is ON. The
cannon plug pins could be damaged by sparks.
After changing programs/parameters, or after maintenance/inspection, always carry out a test
operation before starting actual operation.
Use the power (input voltage, input frequency, tolerable instantaneous power failure time) that are
complied with the power specification conditions indicated in each Specifications manual.
When making detector cables, do not mistake connection. Failure to observe this could result in
malfunction, runaway or fire.
When using NC card, first power ON the NC card, and then the base I/O unit. If the base I/O unit is
powered ON first, current flows from the connection cable to the NC card, resulting in malfunction in
the PC or the cards installed in the PC.

(5) Troubleshooting
CAUTION
Use a servomotor with electromagnetic brakes
or establish an external brake mechanism for
the purpose of holding; this serves as
countermeasures for possible hazardous
situation caused by power failure or product
fault.
Use a double circuit structure for the
electromagnetic brake’s operation circuit so
that the brakes will activate even when the
external emergency stop signal is issued.

The machine could suddenly restart when the power is restored after an instantaneous power
failure, so stay away from the machine. (Design the machine so that the operator safety can be
ensured even if the machine restarts.)
To secure the absolute position, do not shut off the servo drive unit’s control power supply when its
battery voltage becomes low (warning 9F)
If the battery voltage drop warning alarm occurs, make sure to back up the machining programs,
tool data and parameters, etc. with the input/output device before replacing the battery.
Depending on the level of voltage drop, there is the possibility of memory loss. Reload all the data
backed up before the alarm occurrence.
(6) Maintenance, inspection and part replacement
CAUTION
Periodically back up the programs, tool data and parameters to avoid potential data loss. Also, back
up those data before maintenance and inspections.
When replacing the battery on the controller side, the machining programs, tool data and
parameters, etc., should be backed up with the input/output device beforehand.
In case the memory is damaged in replacing the batteries, reload all the data backed up before the
alarm occurrence.
The electrolytic capacitor’s capacity will drop due to deterioration. To prevent secondary damage
due to capacitor’s faults, Mitsubishi recommends the electrolytic capacitor to be replaced approx.
every five years even when used in a normal environment. Contact the Service Center or Service
Station for replacements.
Do not perform a megger test (insulation resistance measurement) during inspection.
Do not replace parts or devices while the power is ON.
