Motion control axis states
The basic rule for the behavior of the axis at a high level when multiple motion
control function blocks are activated is that motion commands are always taken
sequentially, even if the controller has the capability of real parallel processing.
Any motion command is a transition that changes the state of the axis and, as a
consequence, modifies the way the current motion is computed.
