WARNING
1. Electric shock prevention
Do not open the front cover while the power is ON or during op eration. Failure to observe this
could lead to electric shocks.
Do not operate the unit with the front cover removed. The high voltage termi nals and charged
sections will be exposed, and can cause electric shocks.
Do not remove the front cover even when the power is OFF unl ess carrying out wiring work or
periodic inspections. The inside of the units is charged, and can cause electric shocks.
Wait at least 15 minutes after turning the power OFF before startin g wiring, maintenance or
inspections. Failure to observe this could lead to ele c tric shocks.
Ground the servo drive unit and servomotor with Class C (former class 3) grounding or higher.
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.
CAUTION
1. Fire prevention
Install the servo drive units, servomotors and regenerative resistor on noncombu stible
material. Direct installation on combustible material or near com bustible materials could lead
to fires.
Shut off the power on the servo drive unit side if the servo drive uni t fails. 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 erro r 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 wa ter, or if the poles are
incorrectly wired.
2. Injury prevention
Do not apply a voltage other than that specified in Instruction 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.
The servo drive unit's fins, regenerative resistor and servomotor, etc., may reach high
temperatures while the power is ON, and may remain hot for some time after the power is
turned OFF. Touching these parts could result in burns.
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.
