5.2.11
Applications Where the Surrounding Air Temperature of
the Servomotor Exceeds 40°C
The Servomotor ratings are the continuous allowable values at a surrounding air temperature of
40°C. If you use a Servomotor at a surrounding air temperature that exceeds 40°C (60°C
max.), apply a suitable derating rate from the following graphs.
When using Servomotors with derating
tion timing in advance based on the overload detection level of the motor. Refer to the following
section for the overload detection level of the motor.
5.2.7 Servomotor Overload Protection Characteristics on page 5-11
Note: 1. Use the combination of the SERVOPACK and Servomotor so that the derating conditions are satisfied for
both the SERVOPACK and Servomotor.
2. The derating rates are applicable only when the average motor speed is less than or equal to the rated
motor speed. If the average motor speed exceeds the rated motor speed, consult with your Yaskawa rep-
resentative.
