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 technical 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 packing 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.
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.
• The cables must be secured in place.
• Observe the minimum bending radii given in the following table and perform
wiring so that force is not applied to the cables.
