Process data

Process data are commands and setpoints which are entered into the common rectifier from "outside" as well
as signals and actual values which the common rectifier outputs.
4.3.1.1

Control word (control word 1 and control word 2)

Control/status word for 12-pulse mode, see Section 3.8
4.3.1.1.1

Introduction and application example

The two control words 1 (bits 0 to 15) and 2 (bits 16 to 31) output commands and external signals (messages)
to the common rectifier.
Their status can be read-out via parameter r550 or r967 (control 1) and r551 (control word 2).
An overview is provided in Section 4.3.1.1.2 "Overview of the control word".
The significance of the possible commands and signals, entered externally, is described in Section 4.3.1.1.7
"Significance of the control word commands".
Every control word bit is assigned a selection parameter, which defines from which source(s) this bit can be
changed (refer to Section 4.3.1.1.2, right-hand column).
The selection parameters for the sources are, with the exception of P590 (source selection for control word bit
30 "basic/reserve setting") and P591 (source selection for control word bit 31 "Main contactor checkback
signal") are indexed 2x as follows:
Index
An overview of possible sources, which are assigned fixed values (0-6005, non-consecutively), are provided in
Section 4.3.1.1.3 to 4.3.1.1.6 "Selecting the source for the control word".
In this overview, values 0 and 1 are an exception; sources are not selected with these values, but the bits are
set permanently to 0 (LOW) or 1 (HIGH) (also refer to select parameters P554 to P591 in Section 5 "parameter
list").
The control word commands "OFF2" (bit1) and "Acknowledge" (bit7) are always simultaneously effective from
3 sources (can be parameterized) !
"Acknowledge" (bit7) is also always effective from the PMU !
If the "On" command (bit 0) is connected to a serial interface (SST1, CB/TB, SCB-SST), then the following
must be observed for safety-related reasons:
Additionally, an "OFF2" command must be parameterized at the terminal strip/PMU, as otherwise the
converter cannot be shutdown with a defined command, when communications fail!
In order to avoid having to wait until the link circuit voltage drops below 20% of 1.35
a switching-off command, set the parameter P554.i001 = P555.i001 and P554.i002 = P555.i002.
