4.4 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.

02 6 kHz 240.0 Hz (600.0 Hz) 50ºC or 100%

03 8 kHz 240.0 Hz (999.9 Hz) 43ºC or 92%

04 10 kHz 240.0 Hz (999.9 Hz) 35ºC 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.
