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 motor, do not heat the rotor higher than
130°C. The magnet could be demagnetized, and the specifications characteristics will not
be ensured.

Do not reverse the direction of a diode which connect to a DC relay for the control output
signals 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 connection 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 as the operatio n could become unstable.
(4) Usage methods
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
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.
CAUTION
Shut off with the servomotor
brake control output.

Always turn the input power OFF when an alarm occurs.
Never go near the machine after restoring the power after a power failure, as the machine
could start suddenly. (Design 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 inspection after backing up the servo drive unit's programs
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 (insulation resistance measurement) during inspections.
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 disassemble 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 servomotor parts.
Dispose of the battery according to local laws.

1-1-3 Cautions for mounting load (prevention of impact on shaft)
[1] When using the servomotor with key way, use
the screw hole at the end of the shaft to mount
the pulley onto the shaft. To install, first place
the double-end stud into the shaft screw
holes, contact the coupling end surface
against the washer, and press in as if
tightening with a nut. When the shaft does not
have a key way, use a frictional coupling, etc.
[2] When removing the pulley, use a pulley
remover, and make sure not to apply an
impact on the shaft.
[3] Install a protective cover on the rotary sections such as the pulley installed on the shaft to ensure
safety.
[4] The direction of the detector installed on the servomotor cannot be changed.

CAUTION
during assembly.
1-1-4 Installation direction
[1] There are no restrictions on the installation direction. Installation
in any direction is possible, but as a standard the motor is
installed so that the motor power line and detector cable cannon
plugs (lead-in wires) face downward. Installation in the standard
direction is effective against dripping. Measure to prevent oil and
water must be taken when not installing in the standard direction.
When the motor is not installed in the standard direction, refer to
section "1-1-6 Oil/water standards" and take the appropriate
measures.
The brake plates may make a sliding sound when a servomotor
with magnetic brake is installed with the shaft facing upward, but
this is not a fault.
Never hammer the end of the shaft

1-1-5 Shaft characteristics
There is a limit to the load that can be applied on the motor shaft. Make sure that the load applied on the
radial direction and thrust direction, when mounted on the machine, is below the tolerable values given
below. These loads may affect the motor output torque, so consider them when designing the machine.

Radial load
Thrust load
L : Length from flange installation surface to center of load weight [mm]
1. Use a flexible coupling when connecting with a ball screw, etc., and keep the
shaft core deviation to below the tolerable radial load of the shaft.
2. When directly installing the gear on the motor shaft, the radial load increases
as the diameter of the gear decreases. This should be carefully considered
when designing the machine.
3. When directly installing the pulley on the motor shaft, carefully consider so
that the radial load (double the tension) generated from the timing belt tension
is less than the values shown in the table above.
4. In machines where thrust loads such as a worm gear are applied, carefully
consider providing separate bearings, etc., on the machine side so that loads
exceeding the tolerable thrust loads are not applied to the motor.
5. Do not use a rigid coupling as an excessive bending load will be applied on
the shaft and could cause the shaft to break.

1-1-6 Oil/water standards
[1] The motor protective format uses the IP type, which complies with IEC
Standard. However, these Standards are short-term performance
specifications. They do not guarantee continuous environmental
protection characteristics. Measures such as covers, etc., must be
taken if there is any possibility that oil or water will fall on the motor,
and the motor will be constantly wet and permeated by water. Note
that the motor’s IP-type is not indicated as corrosion-resistant.
[2] When a gear box is installed on the servomotor, make sure that the oil
level height from the center of the shaft is higher than the values given below. Open a breathing
hole on the gear box so that the inner pressure does not rise.

constantly contact the motor, enter the motor, or accumulate on the motor. Oil
can also enter the motor through cutting chip accumulation, so be careful of
CAUTION
this also.
2. When the motor is installed facing upwards, take measures on the machine
side so that gear oil, etc., does not flow onto the motor shaft.
3. Do not remove the detector from the motor. (The detector installation screw is
treated for sealing.)

1-1-7 Cable stress
[1] Sufficiently consider the cable clamping method so that bending stress and the stress from the
cable's own weight is not applied on the cable connection part.
[2] In applications where the servomotor moves, make sure that excessive stress is not applied on the
cable.
If the detector cable and servomotor wiring are stored in a cable bear and the servomotor moves,
make sure that the cable bending part is within the range of the optional detector cable.
Fix the detector cable and power cable enclosed with the servomotor.
[3] Make sure that the cable sheathes will not be cut by sharp cutting chips, worn by contacting the
machine corners, or stepped on by workers or vehicles.
The bending life of the detector cable is as shown below. Regard this with a slight allowance. If the
servomotor/spindle motor is installed on a machine that moves, make the bending radius as large as
possible.

If required, install a fan in the panel to agitate the heat in the upper portion of the
units.
1-3-3 Prevention of entering of foreign matter
Treat the cabinet with the following items.
• Make sure that the cable inlet is dust and oil proof by using
packing, etc.
• Make sure that the external air does not enter inside by
using head radiating holes, etc.
• Close all clearances.
• Securely install door packing.
• If there is a rear cover, always apply packing.
• Oil will tend to accumulate on the top. Take special
measures such as oil-proofing to the top so that oil does
not enter the cabinet from the screw holds.
• After installing each unit, avoid machining in the periphery.
If cutting chips, etc., stick onto the electronic parts, trouble
may occur.
• When using the unit in an area with toxic gases or high
levels of dust, protect the unit with air purging (system to
blow clean air so that the panel's inner pressure is higher
than the outer pressure).

Design the panel's heating value taking the actual axis operation (load rate) into
consideration. With a general machine tool, the servo drive unit's load rate is
POINT
approx. 50%, so the heating values inside the panel are half the values shown
above. (Excluding the power supply and spindle drive unit.)
(Example 1)
When using MDS-C1-CV-260, MDS-C1-SP[]-185 and MDS-C1-V2-3535
Total heating value = (40 + 220) + (62 + 280) + (51 + 209) = 862 [W]
Heating value in panel = (40) + (62) + (51 × 0.5) = 127.5 [W]

1. Installation
1-3-6 Heat radiation countermeasures
In order to secure reliability and life, design the temperature in the panel so that the ambient
temperature of each unit is 55°C or less.
If heat accumulates at the top of the unit, etc., install a fan so that the temperature in the panel remains
constant.
(Note) Due to the structure, heat easily accumulates at the
top of the unit. Install a fan in the power distribution
panel to circulate the heat at the top of the unit.
