Motion control instructions

MC_ MoveAbsolute

MC_MoveAbsolute commands a controlled motion to a specified absolute

MC_MoveAbsolute operation

For a Micro800 controller, the sign of the input Velocity for a

MC_MoveAbsolute function block is ignored because the motion direction

is determined by the Current position and the Target position.

For a Micro800 controller, the input Direction for a MC_MoveAbsolute

function block is ignored because there is only one mathematical solution to

reach the Target position.

If the MC_MoveAbsolute function block is issued when the Micro800

controller axis state is StandStill and the relative distance to move is zero,

the execution of the function block is immediately reported as Done.

If a MC_MoveAbsolute function block is issued to an axis that is not in the

Homed, position, the function block reports an error.

The MoveAbsolute function block completes with Velocity zero if it is not

aborted by another function block.
