Power derating
Derating may be necessary at high ambient temperature or when
operating at a great height above sea level. In addition, some mo-
tors may experience power reductions depending on the feedback
system installed or the holding brake [+]. The reduction affects the
standstill current and the standstill torque.
Ambient temperature
fT = Temperature utilization factor
tA = Ambient temperature in °C
Calculation of the performance data if the specified temperature limit
> 40 °C to 55 °C is exceeded:
M0_red = M0 x fT
Installation altitude
fH = Altitude utilization factor
h = Altitude in meters
Calculation of the performance data if the specified installation alti-
tude is exceeded > 1000 m to 3000 m:
M0_red = M0 x fH
Ambient temperature and installation altitude
Calculation of the power data when exceeding the specified limits:
Ambient temperature > 40 °C, altitude > 1000 m and < 3000 m:
M0_red = M0 x fT x fH
