Rectifier/Regenerating Unit Operating Instructions
4.4 Function diagrams
Notes on the function diagrams:
The function diagrams on the two following sheets show the controller structure of the infeed/regenerative
feedback unit.
A value in brackets
for a parameter indicates the factory setting of the parameter in question.
Switch positions
drawn are the factory setting.
These function diagrams also contain parameters that are not
listed in the parameter list (Chapter 5) of these
operating instructions. They are the expert parameters
that are only visible at the PMU if P051 = 3 and
P799 = 4. These expert parameters contain a useful factory setting and must not
usually be altered.
Not only the parameter but also the most important "connectors" (Kxxx) are drawn into the function diagrams.
Connectors
can be seen as "digital measuring points" of internal controlled variables or memory locations (e.g.
DC link voltage K287, DC link current K114, control angle K100). The connectors are only used for factory
internal diagnostic purposes and are not described in more detail in these operating instructions. A hexadecimal
display of a single connector value is possible using the expert parameters P787 and r786 on the PMU
by
parameterizing the number of the connector to be displayed at parameter r786 at P787.
