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 specification operating mode (MDI) can also be used in positioning or
setup mode if the axis is not homed. This means that on-the-fly synchronization and re-
homing can be carried out with "flying referencing" (see separate section).
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 "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.
