Chapter 7 Motion Control
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.
