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 .

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 .
