Gefran is showcasing its new SieiDrive ADV200 AC inverter family with FOC (field oriented control) on stand D50 at Drives & Controls 2008. Aimed at system builders and OEMs, the range covers power ratings from 0.75kW to 1.5MW and can be configured for open-loop or closed-loop speed feedback as well as flux vector or V/f control. The modular design provides up to three option cards for complete application flexibility. Any variety of encoder interfaces, various fieldbus interfaces and I/O expansion cards can be chosen and drives can be mixed together in any combination. Fieldbus options include CANopen, DeviceNet, Profibus-DP as well as Gefran's GD-Net real time fast Ethernet.
The drive includes an easy-to-use keypad with a backlit four-line text display for direct parameter programming. Gefran's GF-eXpress configuration tool with an integrated oscilloscope is also available for fast set-up and application commissioning. For more advanced applications, the ADV200 includes an IEC 61131-3 sequential PLC with Gefran's MDPLC advanced development software.
Gefran is also profiling its GF_VEDO high-performance industrial computers and operator panels for control and display, highlighting the range as a single tool for HMI and PLC. The range covers screen sizes from 3.5in to 15in with touch screens, integrated or non-integrated keyboards, integrated and remote I/O and customised products. With IEC 61131-3, support for Gefran's GD-Net real-time Ethernet and many other protocols, the GF Vedo family helps to reduce development timescales and support application scalability for automation systems of all sizes.
The UK subsidiary of Gefran SpA provides complete sales, technical support and extensive stock facilities for a wide range of automation equipment including industrial computers, PLC equipment, variable-speed and servo drives in addition to a wide range of sensors, temperature controllers, solid state relays and digital indicators as well as safety light guards.
