Beckhoff Extends AX2000 Servo Drive Series with New AX2500 Series

9/29/2003 - The AX2500 series is being integrated into the Beckhoff modular drive concept as an extension of the reliable AX2000 servo drive series. The AX2500 servo drives are fully software compatible with the AX2000 and provide maximum output in the smallest space. In its maximum configuration the multi-axis system comprises eight axes, i.e. a master module with seven axis modules.

The Beckhoff drive system is very well equipped for single- and multi-axis positioning tasks with high dynamic requirements thanks to its efficient IPC hardware and its TwinCAT automation and motion control software. With the expansion through the new AX2500 series servo drives the drive system will be more flexible and even more interesting, especially for compact and space-saving applications - suitable for 300 mm control cabinets.

The master module contains power supply unit, mains filter for power and auxiliary voltage, ballast circuit and resistor as well as a power output stage and can also be operated stand-alone. The subsequent - up to seven - additional axis modules are simply plugged directly into the master module and are connected in the intermediate DC circuit via a socket strip. The 24 V DC auxiliary voltage is similarly looped through this. This provides the user with a very compact, cost-optimised servo system, which is flexibly adaptable to the respective requirements.

Compared with single axes, the wiring and commissioning effort is reduced significantly. The modular concept also minimises possible sources of error. Similar to the AX2000 system, the variable fieldbus connection enables simple integration into various control worlds: Lightbus, Profibus DP, SERCOS interface and CANopen. A coupling module for the new EtherCAT system is in course of preparation.

Together with the AM2000 servomotors the servo drives form an efficient, high dynamic drive unit. The AX2500 servo drive can be used for motors with resolver or with single-turn/multi-turn absolute encoder. The operation of linear and asynchronous motors is also possible. Ready-made motor and feedback lines are offered as accessories. The master module is available in four and the axis module in two different output versions.
