Installation Conditions
The service life of a Servomotor will be shortened or unexpected problems will occur if the Ser-
vomotor is installed incorrectly or in an inappropriate environment or location. Always observe
the following installation instructions.
8.1.1
Installation Precautions
•
Use the lifting bolts on the Servomotor to move only the Servomotor. Never use the lifting
bolts on the Servomotor to move the Servomotor while it is installed on the machine. There is
a risk of damage to the Servomotor or injury.
•
Do not over-tighten the lifting bolts. If you use a tool to over-tighten the lifting bolts, the
tapped holes may be damaged.
•
Do not hold onto the cables or motor shaft when you move the Servomotor. Doing so may
result in injury or damage.
•
Do not install the Servomotor in the following locations. Doing so may result in fire, electric
shock, or damage.
Outdoors or in locations subject to direct sunlight
Locations subject to condensation as the result of extreme changes in temperature
Locations subject to corrosive or flammable gases or near flammable objects
Locations subject to dust, salts, or iron dust
Locations subject to oil drops or chemicals
Locations subject to shock or vibration
Locations that would make it difficult to inspect or clean the Servomotor
•
Mount the Servomotor to the machine so that the cables and connectors are not subjected
to stress.
•
Implement suitable countermeasures, such as attaching a cover, if the Servomotor is used in
an application where it is subject to excessive water or oil drops. We recommend that you
keep the connectors facing downward.
•
Do not connect a Servomotor with an Absolute Encoder or a Servomotor with a Batteryless
Absolute Encoder in a location where there is a magnetic field with a magnetic flux density of
0.01 tesla (100 gauss) or higher.
•
Mount the Servomotor securely to the machine. If the Servomotor is not mounted securely,
the machine may be damaged or injury may occur.
•
Do not step on or place a heavy object on the Servomotor. Doing so may result in injury.
•
Do not allow any foreign matter to enter the Servomotor.
•
For a Servomotor with a Cooling Fan, provide at least 200 mm of space around the fan inlet.
•
To prevent electric shock, ground the Servomotor securely.
•
Servomotors are precision devices. Never drop the Servomotor or subject it to strong shock.
•
Implement safety measures, such as installing a cover, so that the motor shaft and other
rotating parts of the Servomotor cannot be touched during operation.
•
Continuous operation in one direction, such as for a fan, may damage the bearings due to
electrolytic corrosion. Contact your Yaskawa representative if you use a Servomotor for this
type of application.
•
A Servomotor that has been stored for a long period of time must be inspected before it is
used. Contact your Yaskawa representative for more information.
•
Using a Servomotor for oscillating rotation may reduce the service life of the bearings. (Oscil-
lating rotation is defined as a continuous forward-reverse operation within a 150
°
rotation
angle of the motor shaft.) Rotate the Servomotor one full turn or more at least once a day.
•
Never attempt to disassemble or modify a Servomotor.
