Extruder Control
High starting torque, accurate speed/torque control
without encoder for demanding extruder applica
tions. Integrated Decanter Control for the accu
rate speed difference control two shafts, where
direct communication via the fibre optic link between

Master/Follower Control
Reliable control via the fibre optic link several
drives when motor shafts are coupled together.
Thanks Master/Follower function the load can be
evenly distributed between the drives.
Benefits with System Application
• Extended communication capability, data words
available for both directions between the drive and
overriding system..
Pump and Fan Control
Better flow control and cost savings for parallel
motors various industrial pump and fan applications.
Featuring many important PFC functions, including
sleep/ wake and autochange etc. The extruder screw and other delicate mechanical
parts can protected against overload. The basic control modes are speed
control and torque control.
3AFE 68248531 REV 31. Proprietary (DDCS,
Drive bus) and generic (PROFIBUS, InterBus,
DeviceNet) protocols enable linking drives to
controllers, PLC and PCs.
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. 5)
