31 SM01P
15 DESCRIPTION OF PARAMETERS
P01 LINE VOLTAGE SELECTION
Parameter P01 calibrates the drive for the actual applied input voltage. Set this parameter
to HIGH (01) for 120, 220-240, and 460-480 Vac input, or LOW (02) for 200-208 and
380-415 Vac input.
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
Parameter P02 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 40°C or 100%
02 6 kHz 40°C or 100%
03 8 kHz 40°C or 100%
04 10 kHz 35°C or 92%
NOTE
• The SCL/SCM drive is fully rated up to 8 kHz carrier frequency. If the 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.
P03 START METHOD
WARNING!
Automatic starting of equipment may cause damage to equipment and/or injury to
personnel! Automatic start should only be used on equipment that is inaccessible
to personnel.
01 NORMAL: The drive will start when the appropriate contact is closed on the terminal
strip. See Section 11 for possible control configurations.
02 START ON POWER UP: The drive will automatically start upon application of input
power.
