The major features are the soft changeover between
the speed and torque control modes, drooping in
speed control, fast Master-Follower link between two
or more drives and inertia compensation.
Master/Follower Control
Reliable control via the fibre optic link several
drives when motor shafts are coupled together. Integrated Decanter Control for the accu
rate speed difference control two shafts, where
direct communication via the fibre optic link between
bowl and scroll used.
Extruder Control
High starting torque, accurate speed/torque control
without encoder for demanding extruder applica
tions.
Thanks Master/Follower function the load can be
evenly distributed between the drives. The extruder screw and other delicate mechanical
parts can protected against overload. Fast communication with
the overriding controller can exchange operative data
(references, command words) and support data
(configuration data, diagnostics).
Featuring many important PFC functions, including
sleep/ wake and autochange etc.2004 29

Benefits with System Application
• Extended communication capability, data words
available for both directions between the drive and
overriding system.
■
System Application
The software targeted for multi-motor machines
producing processing metal, paper, plastics, textile,
rubber, cement, and for numerous other demanding
applications. Proprietary (DDCS,
Drive bus) and generic (PROFIBUS, InterBus,
DeviceNet) protocols enable linking drives to
controllers, PLC and PCs. The basic control modes are speed
control and torque control..
