2.10 Mounting servo motors
Be sure to use the servo motor within the specified environment, and mount the servo motor on a machine
having the equivalent heat dissipation effect as the following aluminum flange.
The temperature of the servo motor increases differently depending on its mounting environment, operating
conditions, etc. Make sure to check the temperature with an actual machine.

2.11 Restrictions when using the equipment at altitudes exceeding 1000 m and up to 2000 m above sea
level
As heat dissipation effects decrease in proportion to decreasing air density, use the equipment within the
effective load ratio and regenerative load ratio shown in the following figure.
