3.1 Servomotor Installation3.1.1 Installation Precautions3-23.1 Servomotor InstallationThe 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 observethe following installation instructions.3.1.1 Installation Precautions• Do not hold onto the cables or motor shaft when you move the Servomotor. Doing so mayresult in injury or damage.• Do not install the Servomotor in the following locations. Doing so may result in fire, electricshock, or damage.Outdoors or in locations subject to direct sunlightLocations subject to condensation as the result of extreme changes in temperatureLocations subject to corrosive or flammable gases or near flammable objectsLocations subject to dust, salts, or iron dustLocations subject to oil drops or chemicalsLocations subject to shock or vibrationLocations 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 subjectedto stress.• Implement suitable countermeasures, such as attaching a cover, if the Servomotor is used inan application where it is subject to excessive water or oil drops. We recommend that youkeep the connectors facing downward.• 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 allow any foreign matter to enter the Servomotor.• 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 otherrotating parts of the Servomotor cannot be touched during operation.• Continuous operation in one direction, such as for a fan, may damage the bearings due toelectrolytic corrosion. Contact your Yaskawa representative if you use a Servomotor for thistype of application.• A Servomotor that has been stored for a long period of time must be inspected before it isused. 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° rotationangle 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.
