Drives connected Master-Follower application
If motors run with the same
speed torque connected to
the same shaft gearbox are
called MASTER FOLLOWER.
This configuration delivers the
same advantages concerning
harmonics the network a
standard 12- pulse application

tor needed.
The firmware interface for several fieldbuses and mod
ule bus included. The flexible design for command location enables
field bus control master-follower control control
from hardware signals well mixed structure.
Five macros are pre-defined and two user macros can
be configured the customer.
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.
It possible connect
two 12-pulse systems con
verters, T-reactor and motor)
to one 12-pulse transformer.
