Rectifier/Regenerating Unit Operating instructions
3.8.4 Control/status word for 12-pulse mode (r599) and control word 2, bit 23
The following table shows how the bits of the control/status word for 12-pulse mode (r599) are formed from the
bits of control words 1 and 2 (r550, r551), the bits of status word 1 (r552), the bits of the first SST2 receive
data (r599 sent from the Peer-to-Peer partner) and the internal unit status with Boolean arithmetic or how these
bits are connected together (negation is represented with a slash) :
Control/status word for 12-pulse mode (r599)
Bit Logical linking (or meaning in the high state):
r599.0
r550.0 (ON or not OFF1) AND /r552.3 (no fault) AND r551.23 (12-pulse mode is selected)
r599.1
r550.1 (run condition or not OFF2) AND /r552.3 (no fault) AND r551.23 (12-pulse mode is selected)
r599.2
r550.2
r599.3
r552.2 (Message for RUN state)
r599.4
(for internal diagnostic purposes: 1, as long as trigger delay is running, as of Software Version 4.3)
r599.5
Message: Unit is a Rectifier/Regenarating Unit (high state: Unit is a comon rectifier)
(P070 ≤ 100) (P070 ≥ 101)
r599.6
Message: DC link forming or current identification is being carried out
r599.7
r550.7 (fault reset)
r599.8
r550.8 (typing 1 ON) AND /r552.3 (no fault) AND r551.23 (12-pulse mode is selected)
r599.9
r550.9 (typing 2 ON) AND /r552.3 (no fault) AND r551.23 (12-pulse mode is selected)
r599.10
r550.10 (PLC control)
r599.11
r550.11 (Ud-reduction requested)
r599.12
r552.10 (Message: "Regenerating ready") or
High when with 12-pulse mode selected (r551.23= 1), the unit is held in state r000 = "--" (because
"circuit identification" or "forming" is taking place on the partner unit, or because the unit is waiting
for the "run" state of the 12-pulse slave unit (while the slave unit is carrying out the earth short-
circuit test and the maximum waiting time of 5 s in state r000 = "--" has not yet elapsed))
r599.13
r552.3 (Message: NO fault)
r599.14
r552.14 (Message: "Motoring" (Rectifier bridge is carrying current or is ready to carry current or
neither rectifier nor regenerating bridge are carrying current))
r599.15
r550.15 (No external fault 1)
