Example of parameter behavior
The behavior of the parameters of Motion Control instructions is shown by way of the
example of two "MC_MoveAbsolute" jobs.
Using "Exe_1", an "MC_MoveAbsolute" job (A1) with target position 1000.0 is initiated.
"Busy_1" is set to TRUE. The axis is accelerated to the specified velocity and moved to the
target position (see TO_1.Velocity and TO_1.Position). Before the target position is reached,
the job is overridden at time
①
by another "MC_MoveAbsolute" job (A2). The abort is
signaled via "Abort_1", and "Busy_1" is set to FALSE. The axis is braked to the velocity
specified in A2, and moved to the new target position 1500.0. When the axis reaches the
target position, this is signaled via "Done_2".
