AI1 scaled / uint32Selects speed reference source 1.
Two signal sources can be defined by this parameter and
22.12 Speed ref2 source. A digital source selected by 22.14
Speed ref1 source22.11
Speed ref1/2 selection can be used to switch between the
two sources, or a mathematical function (22.13 Speed ref1
function) applied to the two signals to create the reference.
