Chapter 3 – Twelve–Pulse Parallel Configurations with DCS 600
The DC thyristor power converters from the DCS 600 series are
equipped with a separate optical fibre DDCS link on the SDCS-
CON-2 board for the 12 – pulse communication (V260, located
close to connector X7). No other communication setup is required,
except a communication timeout parameter
This parameter defines the allowed number of control cy-
(47.09).
cles (3.3 ms at 50 Hz) without receiving a valid message. For the
12 – pulse slave, this parameter must be set from default value
to at least "4".
One DDCS dataset in each direction is exchanged between the two
converters. Their content is:

The 12 – pulse Software configuration is based on a 12 – pulse
master converter and a 12 – pulse slave converter.
This is done by setting function specific (master/slave) parameters
and signals (the 12 – pulse related signals and parameters are
mentioned within this chapter; 12 – pulse parameters are mainly
inside parameter group 57).
The 12 – pulse mode is activated by setting the desired control
mode to parameter:
