This rung displays the Feedback word for the PowerFlex 40. N7:1 would be used
elsewhere in the user program. Note that the Feedback for the PowerFlex 40 is set
in Hz and not in engineering units like other PowerFlex drives. For example, "300"
equates to 30.0 Hz (the decimal point is always implied).
