•
Connection of converters in serial (sequential) configuration
•
Master / Follower link [channel 2 on SDCS-AMC-DC boards]
•
Master / Slave 12 – pulse communication link [channel V260 on

In this combination speed, current and field control are performed by
the 12 – pulse master. The 12 – pulse link control directs the firing
angle of the slave.
