Gefran expands ADV200 vector inverter range to 1.2 MW

Gefran has expanded its ADV200 line of high performance, FOC (field oriented control), vector inverters adding three larger frame sizes with heavy duty overload power now available up to 1.2 MW.

Three new larger frame sizes added to advanced 32-bit modular inverter range

Comprehensive choice hardware and software options that simplify installation and reduce development timescales

IEC61131 programming included as standard

The modular range now includes four panel mount and three cabinet-housed drives for continuous service, constant torque power output applications from 0.75 kW to 355 kW at 400 – 480 VAC. With heavy duty and light duty overload management and with a choice of open loop, closed loop with speed feedback, or V/F control, the advanced ADV200 range provides maximum 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.

The ADV200 is aimed at system builders and OEMs requiring an inverter drive platform that is able to meet the needs of the widest possible range of speed control applications. Based on a high performance 32-bit microcontroller providing a closed loop speed regulation up to 0.01% 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 4-line text display can provide a means for direct parameter programming or for simple 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 the most demanding machine control and application integration, an IEC61131-3 sequential PLC is included with Gefran’s MDPLC advanced development software.

To allow integration with factory automation systems, standard fieldbus options include CANopen, DeviceNet, Profibus-DP as well as Gefran’s own GD-Net real-time fast Ethernet for high speed synchronisation between ADV200’s or servo controlled axes from Gefran’s XVy-EV range. As standard, each drive is fitted with 2 analogue inputs and outputs, 6 +2 digital inputs and outputs and 2 relay outputs. Separate machine control expansion cards are available in a 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.

The advanced ADV200 also includes state-of-the-art safety features such as OMEGA clamp for 360º EMC cable shielding, an external 24 VDC power supply for keep-alive on mains input loss, and an optional safety card allowing the motor to be disabled without the use of a safety contactor on the drive output – in compliance with EN954-1 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 EN61800-3.
