High-performance, FOC (field oriented control) vector inverters
Gefran is expanding its family of ADV200 high-performance, FOC (field oriented control) vector inverters by adding three larger frame sizes with heavy-duty overload power now available up to 1.2MW.
The modular range now includes four panel-mount and three cabinet-housed drives for continuous service, constant-torque power output applications from 0.75kW to 355kW at 400-480V AC. With heavy-duty and light-duty overload management and a choice of open-loop, closed-loop with speed feedback, or V/F control, the advanced ADV200 range provides application flexibility with up to three front-mounted option card slots for a mixed combination of encoder and fieldbus interfaces or I/O expansion cards.
Gefran's ADV200 is aimed at system builders and OEMs requiring an inverter drive platform that is able to meet the needs of a wide range of speed control applications. Based on a high-performance 32-bit microcontroller providing a closed-loop speed regulation up to 0.01 per cent and a speed range of 1:1000, the ADV200 includes three levels of programming and control options as standard.
A built-in alphanumeric keypad with a backlit four-line text display can provide a means for direct parameter programming or for simple control.
Configuration and control
For applications requiring an intermediate level of control, Gefran's GF-eXpress configuration tool features an integrated oscilloscope and tools for fast set-up and application commissioning, plus a simple integrated PLC for straightforward I/O control.
For demanding machine control and application integration, an IEC 61131-3 sequential PLC is included with Gefran's MDPLC advanced development software.
To allow integration with factory automation systems, standard fieldbus options include CANopen, DeviceNet and Profibus-DP as well as Gefran's own GD-Net real-time fast Ethernet for high-speed synchronisation between ADV200 inverters or servo-controlled axes from Gefran's XVy-EV range. As standard, each drive is fitted with two analogue inputs and outputs, six digital inputs, two digital outputs and two relay outputs. Separate machine control expansion cards are available in various digital and analogue I/O combinations. An RS485 serial input is also available that may be optionally modified for Modbus RTU to provide peer-to-peer or mutltidrop connection for multi-axis systems.
Safety and EMC
The advanced ADV200 also includes state-of-the-art safety features such as OMEGA clamp for 360-degree EMC cable shielding, an external 24V DC power supply for keep-alive on mains input loss, and an optional safety card enabling a motor to be disabled without the use of a safety contactor on the drive output - in compliance with EN 954-1 category 3.
Features for fast installation include removable easy-access screw terminal connectors and front-facing option card slots, plus the keypad is removable. For maximum reliability the ADV200 also features integrated DC line chokes and input filters for full EMC compliance EN 61800-3.
