5.7.1. Dynamic positioning
Dynamic positioning processes can be performed with the modules
MC_MoveAbsolute, MC_MoveRelative and MC_MoveAdditive. The speed can be
altered dynamically with MC_MoveVelocity.
In the state: ”Discrete Motion”
If another, second positioning process is activated in the "Discrete Motion" state,
the 1st positioning process will be interrupted. The transition to the new destination
occurs dynamically, i.e. without any intervening stop.
In "Continuous Motion" state
If a positioning process (MC_MoveAbsolute, MC_MoveRelative or
MC_MoveAdditive) or a MC_MoveVelocity is activated in the "Continuous Motion"
state, the active function module will then be interrupted. All input variables of the
new positioning process will then be taken over.
Superimposed positioning
Please note also the difference to
superimposed positioning
(see page 199) with
MC_MoveSuperImposed.
Here, the movement of the active function module is executed until the end.
