Direct setpoint specification (MDI)
Description
The direct setpoint input function allows for positioning (absolute, relative) and setup
(endless position-controlled) by means of direct setpoint input (e.g. via the PLC using
process data).
During traversing, the motion parameters can also be influenced (on-the-fly setpoint
acceptance) and an on-the-fly change can be undertaken between the Setup and Positioning
modes.
The "direct setpoint input" mode (MDI) can also be used if the axis is not referenced in the
"setup" or "relative positioning" modes, which means that "flying referencing" (see the
separate section), flying synchronization, and post-referencing are possible.
The direct setpoint input function is activated by p2647 = 1. A distinction is made between
two modes: positioning mode (p2653 = 0) and setup mode (p2653 = 1).
●
In the "positioning" mode, the parameters (position, velocity, acceleration and
deceleration) can be used to carry out absolute (p2648 = 1) or relative (p2648 = 0)
positioning with the parameter p2690 (fixed setpoint position).
●
In the setting-up mode, using parameters (velocity, acceleration and deceleration)
"endless" closed-loop position control behavior can be carried-out.
It is possible to make a flying changeover between the two modes.
If continuous acceptance (p2649 = 1) is activated, changes to the MDI parameters are
accepted immediately. Otherwise the values are only accepted when there is a positive edge
at binector input p2650 (setpoint acceptance edge).
