A.6 Drive Derating Data
The drive can be operated at above rated temperature, altitude and default carrier frequency by derating the drive capacity.
u
Carrier Frequency Derating
Derate drive capacity using Figure A.1 as the carrier frequency of the drive increases above the factory setting.

Temperature Derating
As the ambient temperature for the drive is increased above the drive specification the drive should be derated. Additionally
parameter L8-35 Installation Method Selection on page 186 should be set according to enclosure type and mounting method
as illustrated in Figure A.2.

Output Current Derating Due to Ambient Temperature
Set L8-12 and L8-35 according to the installation conditions when the ambient temperature is above the drive specification
or if drives are side-by-side mounted in a cabinet. The output current is derated as shown in Figure A.2.

Altitude Derating
The drive standard ratings are valid for an installation altitude up to 1000 m. If the altitude exceeds 1000 m, both the drive
input voltage and the rated output current must be derated for 1% per 100 m. The maximum altitude is 3000 m.
