Siemens SIMOTICS S-1FK2 User Manual

Reduce the torques and powers according to the values determined.
Factors for power derating depending on the installation altitude and the ambient temperature
Installation altitude above
sea level in m
Ambient temperature in °C
30 40 45 50 55
1000 1.05 1 0.95 0.89 0.84
2000 1 0.95 0.86 0.8 0.73
3000 0.95 0.89 0.76 0.69 0.62
4000 0.89 0.84 0.65 0.57 0.47
Calculate the derating value for ambient temperatures that are not shown here and installation altitudes
below the maximum values by interpolating. For example: 40 °C at 1500 m above sea level = derating factor
0.965
