Example: Successful Aborted Move
Example: Changing Velocity With No Abort
When changing velocity, generally, an aborted move is not necessary since the function block
is only Busy during acceleration (or deceleration). Only a single instance of the function block
is required.
To bring the axis to a standstill, use MC_Halt.

Aborted move is possible if using two
instances of MC_MoveRelative,
MC_MoveAbsolute. The second instance
can immediately abort the first instance
(and vice versa) for applications where on-
the-fly corrections are needed.
