Yaskawa AC Servo Drive Rotary Servomotor Safety Precautions - Manual (Page 21)

1 Product Handling Precautions
E-19
• Wire the Servomotor so that force is not applied to the cables and con-
nectors.
• An absolute encoder has a magnetic sensor attached to it. Do not install
equipment that exerts a strong magnetic force near the Servomotor (i.e.,
a magnetic force of 0.01 tesla or 100 gauss or higher when measured at
the encoder cover).
Protective Structure of Servomotors
The protection class of a Servomotor depends on the model and option
specifications of the Servomotor.
Confirm the protection class of your Servomotor in the Servomotor manual
or catalog, or on Yaskawa’s product and technical information website
(http://www.emechatronics.com/).
Observe the following precautions in reference to the protective structure
(protection class).
• The protection class indicates the degree of protection against the entry
of water.
• If you use oils, coolants, or other liquids with high permeability, protect
the Servomotor with a cover or other device so that the liquid does not
come into direct contact with the Servomotor.
• The protective structure of the Servomotor does not apply to the shaft
opening. Also, you must use the specified connectors for the Servomo-
tor.
