Servomotor Derating Rates For Surrounding Air Temperatures; Applications Where The Altitude Of The Servomotor Exceeds 1,000 M - YASKAWA E Series Product Manual

7.2.9 Servomotor Derating Rates for Surrounding Air Tem-
peratures
Apply a suitable derating rate from the following graphs according to the surrounding air tem-
perature of the Servomotor (60°C max.).
When using Servomotors with derating, change the overload warning and overload alarm
detection timing in advance based on the overload detection level of the motor. Refer to the fol-
lowing section for the overload detection level of the motor.
7.2.6 Servomotor Overload Protection Characteristics on page 7-7
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.

7.2.10 Applications Where the Altitude of the Servomotor
Exceeds 1,000 m
The Servomotor ratings are the continuous allowable values at an altitude of 1,000 m or less. If
you use a Servomotor at an altitude that exceeds 1,000 m (2,000 m max.), the heat dissipation
effect of the air is reduced. Apply the appropriate 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.
