10.8 Drive Derating
500 YASKAWA SIEPC71061737D GA800 Drive Technical Reference
10.8 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
Table 10.21, Table 10.24, and Table 10.27 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. When A1-02 = 4 [Control Method Selection = AOLV], refer to Table 10.22,
Table 10.25, and Table 10.28.
When A1-02 = 6 [AOLV/PM], refer to Table 10.23, Table 10.26, and Table 10.29.
Note:
The drive only applies the carrier frequency derating of the output current to the reference output current value of oL2 [Drive Overload]. The
drive will not derate the 100% output rated current of parameters and monitors as specified in the output rated current shown in Model-
Specific Specifications (200 V Class) on page 486 and Model-Specific Specifications (400 V Class) on page 488.
