Gefran launches next generation AC Inverter range

The new modular AC Inverter range with built-in features and a wide choice of hardware and software options will simplify installation and reduce application development time

Gefran UK has launched its new SieiDrive ADV200 AC inverter family with FOC (field oriented control).

The next generation 32-bit microcontroller based range covers power ratings from 0.75 kW to 1.5 MW in four modular frame sizes with up to +/-0.01% speed regulation accuracy.

Aimed at system builders and OEMs, application flexibility includes configuration for open loop or closed loop speed feedback as well as flux vector or V/f control whilst the space saving design allows up to three encoder interfaces, fieldbus interfaces or I/O expansion cards to be mixed in any combination.

A range of programming options are available to match application complexity - from a simple menu driven keypad to a full onboard PLC with industry standard IEC61131-3.

For complete integration flexibility the ADV200 has a number of built-in features designed for fast and straightforward system commissioning including DC-choke and input filters, OMEGA clamp for EMC cable shielding, removable easy-access wiring terminations, and front mounted option slots and integral keypad.

A dynamic braking module may also be integrated into drives up to 75kW.

An additional safety option card is included, allowing the motor to be disabled without the use of a safety contactor on the drive output - in compliance with EN954-1 category 3.

The ADV200 includes a removable easy-to-use keypad with a backlit 4-line text display for direct parameter programming.

The Gefran GF-eXpress configuration tool with an integrated oscilloscope is also available for fast set-up and application commissioning and includes an integrated PLC for simple applications.

For demanding machine control, the ADV200 can be supplied with an IEC61131-3 sequential PLC and Gefran MDPLC advanced development software.

Standard fieldbus options include CANopen, DeviceNet, Profibus-DP as well as the Gefran GD-Net real time fast Ethernet which may be used for high speed synchronisation between axes.

Standard regulation stage configuration includes 2 analogue inputs and outputs, 6 + 2 digital inputs and outputs and 2 relay outputs.

The ADV200 also includes an RS485 serial input which may be optionally adapted to Modbus RTU for peer-to-peer or mutltidrop connection for multi-axis systems.

The 400 VAC to 480 VAC range offers closed loop speed regulation accuracy to +/-0.01% of rated motor speed with a range of 1:1000.
