Derating Guidelines
Drive ratings can be affected by a number of factors. If more than one
factor exists, derating percentages must be multiplied. For example, if
a 42 Amp drive (B025) running at 8 kHz is installed at a 2,000 m
(6,600 ft.) altitude and has a 2% high input line voltage, the actual
amp rating will be:
42 x 94% Altitude Derate x 96% High Line Derate = 37.9 Amps
.
