A.6 Drive Derating Data
A.6 Drive Derating Data
The drive can be operated at above the rated temperature, altitude, and default carrier frequency by derating the drive
capacity.
◆ Carrier Frequency Derating
As the carrier frequency of the drive is increased above the factory default setting, the drive’s rated output current must
be derated according to Figure A.1 to Figure A.6.
