Field Description
Offset-corrected V and W phase raw current from the IR2175 current
sensor. Values range from 0 - 4096, where 2048 corresponds to 0
current.
CurrentFeedbackConfig write register group and the current sense
resistor value determine the full scale current value.
Synchronous or rotating frame direct and quadrature current values
in 2’s complement representation. The full scale current values range
from –16384 to 16383.
Synchronous or rotating frame direct and quadrature voltage values
in 2’s complement representation. Data ranges are ± VdLim for Ud
and ± VqLim for Uq as specified in the CurrentLoopConfig write
register group.
