Description
0: Disable
1: Enable
Note: Automatic carrier frequency reduction
indicates that the VFD automatically
reduces the carrier frequency when
detecting the heat sink temperature exceeds
the rated temperature. When the
temperature decreases to a specified value,
the carrier frequency restores to the setting.
This function can reduce the VFD overheat
alarm reporting chances.
