Chapter 17 Motion control instructions
458 Rockwell Automation Publication 2080-RM001D-EN-E - February 2015
MC_MoveAbsolute commands a controlled motion to a specified absolute
position.
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.
