Sets the time that the drive continues running with reduced
carrier frequency after the carrier reduction condition is gone.
Fc Reduct Time
Setting 0.00 s disables the carrier frequency reduction time.
High Cur Alm Sel 0: Disabled

speed.
LCD Display
Selects the level to start frequency reduction or to clear the current
frequency level for automatic carrier frequency reduction.
There is normally no need to change this parameter from the default
value.
0: Reduces the carrier frequency based on the drive rated current that

is not derated.
0: Disabled
1: Reduces the carrier frequency based on the drive rated current that
1: Enabled
is derated by the carrier frequency and the temperature selected for
C6-02.
