7.9 Drive Derating
YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference 543
7.9 Drive Derating
You must derate the drive capacity to operate the drive above the rated temperature, altitude, and default carrier
frequency.
â—† Carrier Frequency Settings and Rated Current Values
Table 7.22, Table 7.23, and Table 7.24 show how the drive rated output current changes when the C6-02 [Carrier
Frequency Selection] 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.
Note:
The drive will apply derating for the rated output current value based on the carrier frequency only to the reference output current value of
the oL2 [Drive Overload]. The derated value for the 100% rated output current in parameters and monitors will not be the same as the rated
output current value shown in the Model Specifications tables.
