MLD-M, Example of Application – Simple Double-Axis
Positioning Control (Pick and Place)

Task Definition – Application Description

Products are to be moved from one place to another place. The axis
motions are carried out one after the other. The control (digital output)
and feedback (digital input) of the pneumatic picker are to be handled via
MLD. The procedure is to be started via a switch-key which is read in at a
digital input at the master.

Control (close picker, open picker) and feedback (picker closed) for the
pneumatic picker are to be controlled via digital I/Os at the SERCOS
slave. This implies the additional task of accessing remote I/Os by means
of MLD-M.

Mechanical configuration:

Picker
