Servomotor Heat Dissipation
The heat generated by a Servomotor dissipates through the motor flange
to the motor mounting (the heat sink). Before you mount a Servomotor,
confirm the appropriate heat sink dimensions for your Servomotor model
in the Servomotor manual or catalog, or on Yaskawa’s product and techni-
cal information website (http://www.emechatronics.com/).
If the application environment makes it difficult to provide an appropriate
size of heat sink, contact your Yaskawa representative. Do not place pack-
ing or any other insulating material between the Servomotor and heat sink.
Doing so will cause the motor temperature to increase, affect resistance to
noise, and may cause motor failure.
Handling Cables
Observe the following precautions when you connect the cables.
• The cables must be secured in place.
• Observe the minimum bending radii given in the following table and per-
form wiring so that force is not applied to the cables.
Cable Diameter Minimum Bending Radius (R)
Less than 8 mm 15 mm min.
8 mm 20 mm min.
Over 8 mm 3 times the cable’s outer diameter min.
