POINT

1. Electric shock prevention
Do not open the front cover while the power is ON or during operation. Failure to observe this could lead
to electric shocks.
Do not operate the unit with the front cover removed. The high voltage terminals and charged sections
will be exposed, and can cause electric shocks.
Do not remove the front cover and connector even when the power is OFF unless carrying out wiring
work or periodic inspections. The inside of the units is charged, and can cause electric shocks.
Since the high voltage is supplied to the main circuit connector while the power is ON or during
operation, do not touch the main circuit connector with an adjustment screwdriver or the pen tip. Failure
to observe this could lead to electric shocks.
Wait at least 15 minutes after turning the power OFF, confirm that the CHARGE lamp has gone out, and
check the voltage between P and N terminals with a tester, etc., before starting wiring, maintenance or
inspections. Failure to observe this could lead to electric shocks.
Ground the unit and motor following the standards set forth by each country.
Wiring, maintenance and inspection work must be done by a qualified technician.
Wire the servo drive unit and servomotor after installation. Failure to observe this could lead to electric
shocks.
Do not touch the switches with wet hands. Failure to observe this could lead to electric shocks.
Do not damage, apply forcible stress, place heavy items on the cables or get them caught. Failure to
observe this could lead to electric shocks.
After assembling the built-in IPM spindle motor, if the rotor is rotated by hand etc., voltage occurs
between the terminals of lead. Take care not to get electric shocks.
WARNING

2. Injury prevention
In the system where the optical communication with CNC is executed, do not see directly the light
generated from CN1A/CN1B connector of drive unit or the end of cable. When the light gets into eye,
you may feel something is wrong for eye.
(The light source of optical communication corresponds to class1 defined in JISC6802 or IEC60825-1.)
The linear servomotor, direct-drive motor and built-in IPM spindle motor uses permanent magnets in the
rotor, so observe the following precautions.
(1)Handling
• The linear servomotor, direct-drive motor and built-in IPM spindle motor could adversely affect
medical electronics such as pacemakers, etc., therefore, do not approach the rotor.
• Do not place magnetic materials as iron.
• When a magnetic material as iron is placed, take safety measure not to pinch fingers or hands
due to the magnetic attraction force.
• Remove metal items such as watch, piercing jewelry, necklace, etc.
• Do not place portable items that could malfunction or fail due to the influence of the magnetic
force.
• When the rotor is not securely fixed to the machine or device, do not leave it unattended but store
it in the package properly.
(2)Transportation and storage
• Correctly store the rotor in the package to transport and store.
• During transportation and storage, draw people's attention by applying a notice saying "Strong
magnet-Handle with care" to the package or storage shelf.
• Do not use a damaged package.
(3)Installation
• Take special care not to pinch fingers, etc., when installing (and unpacking) the linear servomotor.

1. Fire prevention
Install the units, motors and regenerative resistor on non-combustible material. Direct installation on
combustible material or near combustible materials could lead to fires.
Always install a circuit protector and contactor on the servo drive unit power input as explained in this
manual. Refer to this manual and select the correct circuit protector and contactor. An incorrect
selection could result in fire.
Shut off the power on the unit side if a fault occurs in the units. Fires could be caused if a large current
continues to flow.
When using a regenerative resistor, provide a sequence that shuts off the power with the regenerative
resistor's error signal. The regenerative resistor could abnormally overheat and cause a fire due to a
fault in the regenerative transistor, etc.
The battery unit could heat up, ignite or rupture if submerged in water, or if the poles are incorrectly
wired.
Cut off the main circuit power with the contactor when an alarm or emergency stop occurs.
2. Injury prevention
Do not apply a voltage other than that specified in this manual, on each terminal. Failure to observe this
item could lead to ruptures or damage, etc.
Do not mistake the terminal connections. Failure to observe this item could lead to ruptures or damage,
etc.
Do not mistake the polarity (+,- ). Failure to observe this item could lead to ruptures or damage, etc.
Do not touch the radiation fin on unit back face, regenerative resistor or motor, etc., or place parts
(cables, etc.) while the power is turned ON or immediately after turning the power OFF. These parts
may reach high temperatures, and can cause burns or part damage.
Structure the cooling fan on the unit back face, etc., etc so that it cannot be touched after installation.
Touching the cooling fan during operation could lead to injuries.
CAUTION

3. Various precautions

other devices.
Do not install or run a unit or motor that is damaged or missing parts.
Do not block the intake or exhaust ports of the motor provided with a cooling fan.
Do not let foreign objects enter the units or motors. In particular, if conductive objects such as screws or
metal chips, etc., or combustible materials such as oil enter, rupture or breakage could occur.
Provide adequate protection using a material such as connector for conduit to prevent screws, metallic
detritus, water and other conductive matter or oil and other combustible matter from entering the motor
through the power line lead-out port.
The units, motors and detectors are precision devices, so do not drop them or apply strong impacts to
them.
CAUTION

Store and use the units under the following environment conditions.
(Note 1) For details, confirm each unit or motor specifications in addition.
(Note 2) -15°C to 55°C for linear servomotor.
Securely fix the servomotor to the machine. Insufficient fixing could lead to the servomotor slipping off
during operation.
Always install the servomotor with reduction gear in the designated direction. Failure to do so could lead
to oil leaks.
Structure the rotary sections of the motor so that it can never be touched during operation. Install a
cover, etc., on the shaft.
When installing a coupling to a servomotor shaft end, do not apply an impact by hammering, etc. The
detector could be damaged.
Do not apply a load exceeding the tolerable load onto the servomotor shaft. The shaft could break.
Store the motor in the package box.
When inserting the shaft into the built-in IPM spindle motor, do not heat the rotor higher than 130°C. The
magnet could be demagnetized, and the specifications characteristics will not be ensured.
Always use a nonmagnetic tool (explosion-proof beryllium copper alloy safety tool: NGK Insulators, etc.)
when installing the linear servomotor.
Always provide a mechanical stopper on the end of the linear servomotor's travel path.
If the unit has been stored for a long time, always check the operation before starting actual operation.

CAUTION

Always connect the motor to the drive unit's output terminals (U, V, W).
Do not directly connect a commercial power supply to the servomotor. Failure to observe this could
result in a fault.
When using an inductive load such as a relay, always connect a diode as a noise measure parallel to
the load.
When using a capacitance load such as a lamp, always connect a protective resistor as a noise
measure serial to the load.
Do not reverse the direction of a diode which
connect to a DC relay for the control output
signals such as contractor and motor brake
output, etc. to suppress a surge. Connecting it
backwards could cause the drive unit to
malfunction so that signals are not output, and
emergency stop and other safety circuits are inoperable.
Do not connect/disconnect the cables connected between the units while the power is ON.
Securely tighten the cable connector fixing screw or fixing mechanism. An insecure fixing could cause
the cable to fall off while the power is ON.
When using a shielded cable instructed in the instruction manual, always ground the cable with a cable
clamp, etc.
Always separate the signals wires from the drive wire and power line.
Use wires and cables that have a wire diameter, heat resistance and flexibility that conforms to the
system.
(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 changes of parameter as the operation could become
unstable.
The usable motor and unit combination is predetermined. Always check the models before starting trial
operation.

(4) Usage methods
In abnormal state, install an external emergency stop circuit so that the operation can be stopped and
power shut off immediately.
Turn the power OFF immediately if smoke, abnormal noise or odors are generated from the unit or
motor.
Do not disassemble or repair this product.
Never make modifications.
When an alarm occurs, the machine will start suddenly if an alarm reset (RST) is carried out while an
operation start signal (ST) is being input. Always confirm that the operation signal is OFF before
carrying out an alarm reset. Failure to do so could lead to accidents or injuries.
Reduce magnetic damage by installing a noise filter. The electronic devices used near the unit could be
affected by magnetic noise. Install a line noise filter, etc., if there is a risk of magnetic noise.
Use the unit, motor and regenerative resistor with the designated combination. Failure to do so could
lead to fires or trouble.
The brake (magnetic brake) of the servomotor are 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, the machine
construction (when ball screw and servomotor are coupled via a timing belt, etc.) or the magnetic
brake's failure. 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 each specification 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 circuit protector for the main circuit power supply is shared by several units, the circuit protector may
not activate when a short-circuit fault occurs in a small capacity unit. This is dangerous, so never share
the circuit protector.
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.
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
