15.0 DESCRIPTION OF PARAMETERS

P01 LINE VOLTAGE SELECTION

This 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

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.

PARAMETER CARRIER AMBIENT OR OUTPUT

SETTING FREQUENCY DERATE (NOTE 2)

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 %

NOTES:

1. The SM Series

™

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 derated to the value shown in the table above.

2. If this parameter is changed while the drive is running, the change will not take effect until

the drive is stopped.

P03 START METHOD

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.
