Machine controller brings it all together

A Delta Tau UK product story
Edited by the Engineeringtalk editorial team Mar 7, 2005

A novel four-, six- and eight-axis machine controller combines the servo amplifiers and motion controller PLC and user I/O in a single compact unit.

As part of an initiative to deliver advanced and complex machine control in easy to use configurations, Delta Tau has unveiled a four-, six- and eight-axis machine controller that contains the servo amplifiers and motion controller PLC and user I/O in a single compact unit.

Called the Geo Brick 400, the new controller brings together the intelligence and capability of Delta Tau's PMAC2 motion controller - which set the global benchmark for motion control - with the latest IGBT-based servo drive technology.

The flexible nature of the PMAC2 enables the Geo Brick to drive brushed, brushless or AC induction motors with DSP performance.

The absence of analogue signals - required for typical motion controller/drive interfacing - enables higher gains, better overall performance and tighter integration, while significantly reducing both costs and setup time.

The embedded PMAC2 motion controller in the Geo Brick 400 is programmable for virtually any kind of motion control application and it includes PLC programming features for complete machine logic control.

with 24 inputs and 24 outputs integrated into the system and the option to expand this with Modbus over Ethernet, the Brick is set to become the next benchmark product from Delta Tau.

The integrated design of the drive and motion controller provide access of all diagnostic information such as amplifier faults, bus voltage, axis currents, phase current, heatsink temperature and so forth.

This data can be accessed by the PMAC and made available to user-written motion control programs.

The Geo Brick is scaleable automation and control.

The Geo Brick 400 stores programs locally and executes them either by operation of hardware inputs or via Ethernet or high-speed USB 2.0-based communications.

This makes it ideal for applications requiring only I/O-driven servo control where the motion is co-ordinated by a machine controller such as a PLC.

Similarly, the Geo Brick 400 is ideal if the application requires, for example, a complete machine controller with PLC functionality, motion control, expandable I/O via a ModBus TCP master, an HMI terminal via ModBus TCP slave or even a PC-based HMI package connected via USB 2.0 or Ethernet.
