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.
15.0 DESCRIPTION OF PARAMETERS
P01 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.
RATED INPUT INPUT APPLIED INPUT PARAMETER
MODEL VOLTAGE PHASE VOLTAGE SETTING
SF100S 120 / 208 / 240 Vac 1 110 - 120 Vac or 220 - 240 Vac HIGH (01)
1 200 - 208 Vac LOW (02)
SF200Y 208 / 240 Vac 1 or 3 220 - 240 Vac HIGH (01)
1 or 3 200 - 208 Vac LOW (02)
SF200 208 / 240 Vac 3 220 - 240 Vac HIGH (01)
3 200 - 208 Vac LOW (02)
SF400 400 / 480 Vac 3 440 - 480 Vac HIGH (01)
3 380 - 415 Vac LOW (02)
SF500 480 / 590 Vac 3 575 - 600 Vac HIGH (01)
3 460 - 480 Vac LOW (02)
PARAMETER CARRIER MAXIMUM OUTPUT AMBIENT OR OUTPUT
SETTING FREQUENCY FREQUENCY (NOTE 1) DERATE (NOTE 2)
01 4 kHz 240.0 Hz (400.0 Hz) 50 C or 100%
02 6 kHz 240.0 Hz (600.0 Hz) 50 C or 100%
03 8 kHz 240.0 Hz (999.9 Hz) 43 C or 92%
04 10 kHz 240.0 Hz (999.9 Hz) 35 C or 82%
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.
