This rung controls the Reference for the PowerFlex 40. N7:0 would be controlled
elsewhere in the user program. Note that the Reference 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).
