NOTE: If this parameter is changed while the drive is running, the new value will not take effect
until the drive is stopped.
P02
CARRIER FREQUENCY
This sets the switching rate of the output IGBT’s. Increasing the carrier frequency will result in less
audible motor noise. Available settings are: 4 kHz, 6 kHz, 8 kHz, and 10 kHz.

LINE VOLTAGE SELECTION
This calibrates the drive for the actual applied input voltage, and can be set to HIGH (01) or LOW
(02). Refer to the table below for the proper setting depending on the input voltage.

NOTE 1: For drives with the High Output Frequency option, the carrier frequency also determines
the maximum output frequency (shown in parenthesis).
NOTE 2: The SCF drive is fully rated up to 6 kHz carrier frequency. If the 8 kHz or 10 kHz carrier
frequency is selected, the drive’s ambient temperature rating OR output current rating must be de-
rated to the value shown in the table above.
