5.2.12 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.
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

motor speed. If the average motor speed exceeds the rated motor speed, consult with your Yaskawa rep-
resentative.
