This is an exemplary project for an error reaction by IndraMotion
MLD and MPx04 firmware. By means of this example, we will de‐
scribe the basic options of an MLD error reaction. When used in
real machines, the error reaction requires application-specific ad‐
justments!
When an error occurs (F2xxx, F3xxx or F4xxx), an intelligent error reaction is
to be carried out by means of IndraMotion MLD. As the standard error reaction
"best possible deceleration" is unsuitable, a local error reaction is to take place,
particularly when the master communication fails (F4009).
The intelligent error reaction does not work when errors of the error
classes F8xxx, F7xxx and F6xxx occur! In these cases, it is always
the error reaction defined by the drive which is carried out (see sec‐
tion "Error Reactions" in the Functional Description of the
IndraDrive firmware).
The figure below contains an overview of the functional structure of MLD's ap‐
plication example "intelligent error reaction".
Fig.6-1: Structural Overview of the Application Example
The intelligent error reaction is characterized by the following features:
● The error reaction can be parameterized or controlled via global registers
(P‑0‑1370 ff.), as well as analog and digital inputs at the control section.
● Via an analog input, a velocity command value can be preset with which
the drive continues moving after an error has occurred (e.g. for stirring
machines).
