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.
u
Rated Current Depending on Carrier Frequency
The tables below show the drive output current depending on the carrier frequency settings.
The 2 kHz values shown for ND below 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.
