Safety Precautions That Must Always Be Observed
General Precautions
DANGER
There is a risk of electric shock, operational failure of the product, or burning.
WARNING
There is a risk of electric shock or fire.
There is a risk of fire or failure.
The warranty is void for the product if you disassemble, repair, or modify it.
CAUTION
There is a risk of burn injury.
There is a risk of failure, damage, or electric shock.
There is a risk of electric shock or fire.

• Do not attempt to use a SERVOPACK or Servomotor that is damaged or that
has missing parts.
• Install external emergency stop circuits that shut OFF the power supply and
stops operation immediately when an error occurs.
• Select the brake power supply for a Servomotor with a Holding Brake accord-
ing to the power supply voltage and capacity required for the Servomotor
model, as given in manuals and catalogs. Also confirm the input voltage to the
holding brake.
• Always install a surge absorber as a protective device between the brake
power supply and Servomotor.
• The time required for a holding brake to operate depends on the types of pro-
tective devices. The time required for a holding brake to operate will also
change if holding brakes are connected in parallel. Always check the time
required for a holding brake to operate on the actual machine before you oper-
ate a Servomotor.
• Always use a Servomotor and SERVOPACKin one of the specified combina-
tions.
• Do not touch a SERVOPACK or Servomotor with wet hands.

• Do not install or store the product in any of the following locations.
• Although machined surfaces are covered with an anticorrosive coating, rust
can develop due to storage conditions or the length of storage.
If you store the product for more than six months, reapply an anticorrosive
coating to machined surfaces, particularly the motor shaft.
• Consult with your Yaskawa representative if you have stored products for an
extended period of time.

such as the corners.
• Do not place an excessive load on the product during transportation. (Follow
all instructions on the packages.)
E-5
Transportation Precautions
NOTICE
• Locations that are subject to direct sunlight
• Locations that are subject to ambient temperatures that exceed product spec-
ifications
• Locations that are subject to relative humidities that exceed product specifi-
cations
• Locations that are subject to condensation as the result of extreme changes
in temperature
• Locations that are subject to corrosive or flammable gases
• Locations that are near flammable materials
• Locations that are subject to dust, salts, or iron powder
• Locations that are subject to water, oil, or chemicals
• Locations that are subject to vibration or shock that exceeds product specifi-
cations
• Locations that are subject to radiation
If you store or install the product in any of the above locations, the product
may fail or be damaged.
CAUTION
There is a risk of disconnection, damage, or injury.
There is a risk of damage or injury.
There is a risk of injury.
There is a risk of injury or damage.

• A SERVOPACK or Servomotor is a precision device. Do not drop it or subject
it to strong shock.
• Do not subject connectors to shock.
• If disinfectants or insecticides must be used to treat packing materials such as
wooden frames, plywood, or pallets, the packing materials must be treated
before the product is packaged, and methods other than fumigation must be
used.
Example: Heat treatment, where materials are kiln-dried to a core temperature
of 56C for 30 minutes or more.
• Do not overtighten the eyebolts on a SERVOPACK or Servomotor.
E-6
Installation Precautions
NOTICE
There is a risk of failure or damage.
There is a risk of faulty connections or damage.
If the electronic products, which include stand-alone products and products
installed in machines, are packed with fumigated wooden materials, the elec-
trical components may be greatly damaged by the gases or fumes resulting
from the fumigation process. In particular, disinfectants containing halogen,
which includes chlorine, fluorine, bromine, or iodine can contribute to the ero-
sion of the capacitors.
If you use a tool to overtighten the eyebolts, the tapped holes may be damaged.
CAUTION
• Do not touch the key slot with your bare hands on the shaft end on a Servomo-
tor with a Key Slot.
There is a risk of injury.
• Securely mount the Servomotor to the machine.
If the Servomotor is not mounted securely, it may come off the machine during
operation.
• Install the Servomotor or SERVOPACK in a way that will support the mass
given in technical documents.
• Install SERVOPACKs, Servomotors, and regenerative resistors on nonflam-
mable materials.
Installation directly onto or near flammable materials may result in fire.

There is a risk of failure, damage, or injury.
• Do not allow any foreign matter to enter the SERVOPACK or Servomotor.
There is a risk of failure or fire.
• Implement safety measures, such as installing a cover so that the rotating part
of the Servomotor cannot be touched accidentally during operation.

Continued from previous page.
CAUTION

E-8
• A Servomotor is a precision device. Do not subject the output shaft or the
main body of the Servomotor to strong shock.
• Design the machine so that the thrust and radial loads on the motor shaft
during operation do not exceed the allowable values given in the catalog.
• When you attach the key to the motor shaft, do not subject the key slot to
direct shock.
• Do not allow any foreign matter to enter a SERVOPACK or a Servomotor with
a Cooling Fan and do not cover the outlet from the Servomotor’s cooling fan.
There is a risk of failure.
• If you use oil as the gear lubricant, always inject the specified oil before start-
ing operation.
• You can install the Servomotor either horizontally or vertically. However, if
you install a Servomotor with an Oil Seal with the output shaft facing upward,
oil may enter the Servomotor depending on the operating conditions. Confirm
the operating conditions sufficiently if you install a Servomotor with the out-
put shaft facing upward. Some Servomotors with Gears have restrictions on
the installation orientation. Refer to the relevant technical documents.
• If an installation orientation is specified for a Servomotor with a Gear, install
the Servomotor in the specified orientation.
There is a risk of failure due to oil leakage.
• For a Servomotor with an Oil Seal, use the Servomotor with the oil seal in a
lubricated condition with only splashing of oil.
If the Servomotor is used with the oil seal under the surface of the oil, oil may
enter the Servomotor, possibly resulting in failure.
• The shaft opening of a Servomotor is not waterproof or oilproof. Implement
measures in the machine to prevent water or cutting oil from entering the Ser-
vomotor.
There is a risk of failure.
Continued on next page.
• In an application where the Servomotor would be subjected to large quantities
of water or oil, implement measures to protect the Servomotor from large
quantities of liquid, such as installing covers to protect against water and oil.
• In an environment with high humidity or oil mist, face Servomotor lead wires
and connectors downward and provide cable traps.
There is a risk of failure or fire due to insulation failure or accidents from
short circuits.
