Status word (status word 1 and status word 2)

4.3.1.2.1

Introduction and application example

Status words 1 (bits 0 to 15) and 2 (bits 16 to 31) issue messages and commands from the
rectifier/regenerating unit to external destinations.
Their particular status can be read-out via parameters r552 or r968 (status word 1) and r553 (status word 2).
An overview is provided in Section 4.3.1.2.2 "Overview of the status word".
The significance of the possible messages and commands to the outside is described in Section 4.3.1.2.4
"Significance of the status word messages".
Each status word bit is assigned a selection parameter, which defines, to which destination this bit is sent (refer
to Section 4.3.1.2.2, right-hand column).
The selection parameters for the destinations are indexed twice as follows:
Index: i001
i002
An overview of the possible destinations, which are assigned fixed values, is provided in Section 4.3.1.2.3
"Selecting the destinations for the status word".
For the output of faults, alarms and switch-on inhibit of the status word ( HIGH active ) via the terminal strip,
then these are LOW active at the terminals (binary outputs) (i.e.: the relay drops out)!
This is also true for possible option boards!
Also refer to Section 4.3.3 "Binary outputs"
