CAUTION
3. Various precautions
Observe the following precautions. Incorrect handling of the unit could lead to faults, injuries and
electric shocks, etc.
(1) Transportation and installation
Correctly transport the product according to its weight.
Use the servomotor's hanging bolts only when transporting the servomotor. Do not transport
the servomotor when it is installed on the machine.
Do not stack the products above the tolerable number.
Do not hold the cables, axis or detector when transporting the servomotor.
Do not hold the connected wires or cables when transporting the servo drive u nits.
Do not hold the front cover when transporting the servo drive units. The unit could drop.
Follow this Instruction Manual and install in a place where the weight can be borne.
Do not get on top of or place heavy objects on the unit.
Always observe the installation directions.
Secure the specified distance between the servo drive unit and co ntrol panel's inner wall, and
between other devices.
Do not install or run a servo drive unit or servomotor that is damaged or missing parts.
Do not block the intake or exhaust ports of the servomotor provided with a cooling fan.
Do not let foreign objects enter the servo drive units or servomotors. In particular, if
conductive objects such as screws or metal chips, etc., or combustible materials such as oil
enter, rupture or breakage could occur.
The servo drive units and servomotors 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.

To follow each unit and motor
specifications
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 o peration.
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 hi gher than
130°C. The magnet could be demagnetized, and the specifications cha racteristics will not
be ensured.
If the unit has been stored for a long time, always check the operation before starting
actual operation. Please c ontact t he Service Center or Service Station.
CAUTION
(2) Wiring
Correctly and securely perform the wiring. Failure to do so could lead to runaway of the
servomotor.
Do not install a condensing capacitor, surge absorber or radio noise filter on the output side of
the servo drive unit.
Correctly connect the output side (terminals U, V, W). Failure to do so could lead to abnormal
operation of the servomotor.
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 p rotective 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 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.
