10.4 Drive Derating
360 SIEPYEUOQ2A01A AC Drive Q2A Technical Manual
10.4 Drive Derating
You must derate the drive capacity to operate the drive above the rated temperature, altitude, and default carrier
frequency.
◆ Carrier Frequency Settings and Rated Current Values
The following tables show how the drive rated output current changes when C1-02 [Decel Time 1] value changes.
The output current value changes linearly as the carrier frequency changes. You can use the values from the tables
to calculate a frequency that is not shown.
