Derating at altitudes higher than 1000 m above sea level 4.6.2
Derating for operation at altitudes higher than 1000 m above sea level and at standstill of the motor
and a standard ambient temperature
2000 m above sea level 6 %
3000 m above sea level 11 %
4000 m above sea level 17 %
To calculate the holding torque, the permitted torque is to be derated by the following formula:
M
red
= M
0
* sqrt (1-(H-1000)/(10000)).
