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.
◆
Rated Current Depending on Carrier Frequency
Table A.8 shows the drive output current depending on the carrier frequency settings.
Use the data in Table A.8 and Table A.9 to linearly calculate output current values for carrier frequencies not listed in the
tables.
