Basic functions of Rexroth IndraMotion MLD

Overview
The runtime system of the drive-integrated PLC in its MLD-S and MLD-M de‐
signs is embedded in the drive runtime system as a module with its functions
and interfaces.
The figure below illustrates the basic functions of a drive with integrated PLC
and how they interact (here the MLD-S design):

Definition of terms
MLD-S, MLD-M, MLD
The "Rexroth IndraMotion MLD" drive-integrated PLC is available in different
variants.
The variant for single-axis applications is called "MLD-S". In this case, the
control options of the PLC in the device are limited to the "local axis" and the
virtual master axis generator.
If drives with sercos III slave interface are connected via the "CCD" option
(sercos III master interface), the PLC can control these axes. This variant is
called "MLD-M".
The general short form "MLD" is used when describing independent function‐
alities.
