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 basic control modes are speed control and torque control. • Easy installation and start-up reduces the total project costs • Ready use with proven modular crane functionality • Accurate and fast torque response increases the operational productivity • Smooth crane operation reduces maintenance and damage costs • Available single drive and multi-drive with dynamic and regenerative braking Standard ready-to-use crane drive solution with optimal operational safety and outstanding crane drive perfor­ mance. The extruder screw and other delicate mechanical parts can protected against overload. Benefits with System Application • Extended communication capability, data words available for both directions between the drive and overriding system. • PT100 PTC measurement (max. Featuring many important PFC functions, including sleep/ wake and autochange etc. Fast communication with the overriding controller can exchange operative data (references, command words) and support data (configuration data, diagnostics).2004 29 . Proprietary (DDCS, Drive bus) and generic (PROFIBUS, InterBus, DeviceNet) protocols enable linking drives to controllers, PLC and PCs. 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. ■ System Application The software targeted for multi-motor machines producing processing metal, paper, plastics, textile, rubber, cement, and for numerous other demanding applications. Master/Follower Control Reliable control via the fibre optic link several drives when motor shafts are coupled together. and digital (max. motors) • Thermal model for motor cable protection • Motor fan control with diagnostics • Freely programmable outputs: analog (max. 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) • Speed control gain function output low speed function motor frequency Centrifuge Control Practical programmable sequences for conventional centrifuges. Crane Drive Control Cost-effective crane drive control with optimal opera­ tional safety and outstanding performance already built in. • Torsional oscillation damping function damp mechanical oscillations. Pump and Fan Control Better flow control and cost savings for parallel motors various industrial pump and fan applications. 3AFE 68248531 REV 31.3.
