Drive Derating Data

The drive can be operated at above rated temperature, altitude and default carrier
frequency by derating the drive capacity. For example, a 10 amp continuous rated
drive may be operated at higher temperatures if it is only used to supply 8 amps
continuous.
◆

Carrier Frequency Derating

As the carrier frequency of the drive is increased above the factory setting the drive
capacity should be derated according to
Figure A.1
200 V Class:
80% of HD
400 V Class
60% of HD
◆

Temperature Derating

As the ambient temperature for the drive is increased above the drive specification
the drive should be derated. Additionally parameter L8-35 Side-by-Side Selection
on page 395 should be set according to enclosure type and mounting method as
illustrated in Figure A.2 Ambient Temperature and Installation Method Derating
on page 329.
