Function Block Interconnection Of The "Actuating Drive Speed" Application - Lenze E84AVSC Operating Instructions Manual

Function block interconnection of the "Actuating drive speed" application

Every drive solution for the 8400 device series is implemented in the form of a "function
block interconnection" (abbreviated as: "FB interconnection").
Using the function block interconnection, any signal interconnection can be implemented.
Various function blocks are available for digital signal processing, signal conversion and
logic modules.
For special tasks it has proved of value to use the integrated technology applications as a
basis for modifications or extensions of the available FB interconnections.
 From the "StateLine" device version onwards, the preconfigured signal connections can
be reconfigured via parameter setting or via the »Engineer« function block editor in the
"I/O level".
 Moreover, from the HighLine device version experienced users are offered the
opportunity to implement their own drive solutions independent of the predefined
technology applications by using so-called "free interconnections".
Within the FB interconnection, the following modules are distinguished:
Module type
Function block
System block
Port block
Application block
