see anu 12-pulse opera
tion. The harmonics
on the side are reduced
too, which gives higher ef
ficiency.
Five macros are pre-defined and two user macros can
be configured the customer..
The design drive logic enables drive reaction de

Quasi 12-pulse Master-Follower configuration
The converters are fed by
a 12-pulse transformer with
separated secondary windings
whose phase positions differ
by 30°el.
quasi 12-pulse
Typical configuration for high power drives connected in
12-pulse parallel, serial sequential application
12-pulse systems are used
for reduced line harmonics,
reduced motor noise level,
enlarged output current or
voltage converter system.
This configuration delivers the
same advantages concerning
harmonics the network a
standard 12- pulse application
(see next item), but T-reac-
tor needed. The flexible design for command location enables
field bus control master-follower control control
