NOTE: If this parameter is changed while the drive is running, the new value will not take effect
until the drive is stopped.
02 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.
15.0 DESCRIPTION OF PARAMETERS
01 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.
NOTE 1: The SM-Basic 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.
NOTE 2: If this parameter is changed while the drive is running, the change will not take effect until
the drive is stopped.
