Interconnecting signals in the inverter

A.4.1

Fundamentals

The following functions are implemented in the inverter:
● Open-loop and closed-loop control functions
● Communication functions
● Diagnosis and operating functions
Every function comprises one or several blocks that are interconnected with one another.

Most of the blocks can be adapted to specific applications using parameters.
You cannot change the signal interconnection within the block. However, the interconnection
between blocks can be changed by interconnecting the inputs of a block with the appropriate
outputs of another block.
The signal interconnection of the blocks is realized, contrary to electric circuitry, not using
cables, but in the software.
