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 location. Always observe the following
installation instructions.
8.1.1

Installation Precautions

Important
8-2
 Implement safety measures, such as installing a cover so that the rotating part of the Direct
Drive Servomotor cannot be touched accidentally during operation.
 Never use the Servomotor in an environment that is subject to water, corrosive gases, or
flammable gases, or near flammable objects. Failure to observe this caution may result in
electric shock or fire.
• Mount the Servomotor to a nonflammable material. Installation directly onto or near flammable
objects may result in fire.
• Mount the SERVOPACK and Direct Drive Servomotor on a structure that will support the
masses that are given in the user's manuals.
• Do not step on or place a heavy object on the Servomotor. Failure to observe this caution may
result in injury.
• Install the Servomotor within the specified ambient conditions. Refer to the specifications for
each type of Servomotor for the ambient conditions.
• Direct Drive Servomotors are precision devices. Never drop a Servomotor or subject it to
strong shock.
• Do not place a Direct Drive Servomotor with the connector side facing down. Doing so will
damage the connectors.
• Do not place any load on the cover on the rotating part of an SGMCV Direct Drive Servomotor.
Doing so will deform or damage the cover.
• Do not attempt to install or operate a Direct Drive Servomotor that is damaged or missing
parts.
• When you transport a Direct Drive Servomotor, do not hold onto the cables, rotating part, or
connectors. Failure to observe this caution may result in damage or injury.
• Securely mount the Direct Drive Servomotor onto the machine. If the Servomotor is not
mounted securely, it may come off during operation, possibly causing injury.
• When you couple the load to the Direct Drive Servomotor, do not strike the Servomotor with a
hammer or otherwise subject it to shock. Failure to observe this caution may result in damage
to the encoder.
• Do not place more than the allowable load on the rotating part of the Direct Drive Servomotor.
Failure to observe this caution may result in damage to the rotating part.
• Consult your Yaskawa representative if you plan to use a Direct Drive Servomotor that has been
stored for an extended period of time.
• Check the level of vibration while the Direct Drive Servomotor is mounted to the machine. If the
vibration is too strong, the bearings and encoder will be damaged faster, faulty connector con-
tacts may occur, and bolts may become loose.
• When you adjust the gain during equipment commissioning, use a measuring instrument to
monitor the torque waveform and speed waveform and confirm that there is no vibration. If a
high gain causes vibration, the Direct Drive Servomotor will be damaged faster.
