A.4 Drive Derating Data
The drive can be operated at above the rated temperature, altitude, and default carrier frequency by derating the drive capacity.

Rated Current Depending on Carrier Frequency
The table below shows the drive output current depending on the carrier frequency settings.
n
Normal Duty Rating (ND)
The 2 kHz values shown for ND in
are equal to the drive rated current shown on the drive nameplate. Increasing
the carrier frequency above 2 kHz will reduce the ND rated output current of the drive as shown in
