VBUS.ACNOMINAL
Description
This command configures the operating voltage for a level other than the default of the drive.
-
-
The drive can be de-rated but do not operate it higher than the original voltage.
When changed, VBUS.ACNOMINAL modifies the inrush voltage settings and the regen voltage configurations. If it is set to lower than 40% of the standard AC line voltage (e.g., 96V for MV drives where the standard voltage is 240V, or 192V for HV drives where the standard voltage is 480V) then F2014 and W2014 (AC input phase loss) are turned off. It is important that VBUS.ACNOMINAL be set as accurately as possible to minimize voltage faults.
Examples
Code
If an HV drive (480V) was needed for bench testing at 120V, do the following:
VBUS.ACNOMINAL 120
