Applications Where the Surrounding Air Temperature of the Servo Motor
Exceeds 40°C
The Servo Motor ratings are the continuous allowable values at a surrounding air temperature of 40°C. If
you use a Servo Motor at a surrounding air temperature that exceeds 40°C (60°C max.), apply a suitable
derating rate from the following graphs.
When using Servo Motors with derating, change the detection timing of overload warnings and overload
alarms by referring to the motor overload detection level described in the following manual.
-7-Series AC Servo Drive Rotary Servo Motor Product Manual
(Manual No.: SIEP S800001 36)
Note: 1. Use the combination of the SERVOPACK and Servo Motor so that the derating conditions are satisfied for both the
SERVOPACK and Servo Motor.
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 representative.
