SF01U 33
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.

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)
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.

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
• For drives with the High Output Frequency option, the carrier frequency also
determines the maximum output frequency (shown in parenthesis).
• 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.
• If this parameter is changed while the drive is running, the change will not
take effect until the drive is stopped. Therefore, the allowable maximum
frequency for drives with the High Output Frequency option (see NOTE 1) will
not change if the carrier frequency is changed while the drive is running.
