15 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.

TF200 208 / 240 Vac

3 220 - 240 Vac HIGH (01)

3 200 - 208 Vac LOW (02)

TF400 400 / 480 Vac

3 440 - 480 Vac HIGH (01)

3 380 - 415 Vac LOW (02)

TF500 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: 2 kHz, 4 kHz, and 8 kHz.

The TCF drive is fully rated up to 4 kHz carrier frequency. If the 8 kHz carrier frequency is

selected, the drive’s ambient temperature rating must be de-rated to 43°C, OR the output

current rating must be de-rated to 92%.

NOTE

• If the drive's heatsink temperature gets too hot while running, the carrier

frequency will automatically shift to a lower value to increase efﬁciency

and lower heat generation.

• If this parameter is changed while the drive is running, the change will not

take effect until the drive is stopped.
