Motion and machine controllers

Paul Boughton
Delta Tau's Geo Brick LV family of packaged eight-axis motion and machine controllers is available from Heason Technology as part of its motion system design and build service.

The Geo Brick LV and the newly announced 19-in rack mount version, the LV-PC, is supplied with eight user configurable 250W drives for linear or rotary brushed and brushless servos, ceramic motors or stepper motors in any mix with  feedback interfaces that include practically all commercially available types available today.

Furthermore, a comprehensive selection of fieldbus and communications options, expandable machine I/O and the powerful PMAC multi-axis motion control engine make the Geo Brick LV family a perfect and flexible motion controller for applications where a combination of motor technologies is required such as packaging machines or equally for complex multi-axis positing systems for research.

The Geo Brick LV's flexibility can also be increased for up to 16-axes of motion control using Delta Tau's fibre optic interface port (MACRO) - and higher power third-party servo amplifiers and stepper drives from Heason Technology's manufacturing partners can be accommodated using on-board analogue outputs or with pulse and direction control from digital I/O.

The Geo Brick LV's motion control capability spans simple single axis point to point motion to extremely complex multi-axis motion incorporating forward and inverse kinematics calculations with advanced math capability. Ensuring ease of control for the most demanding applications, the powerful multi-tasking motion controller includes 64 user PLCs for asynchronous tasking and two high speed PLCs that run at servo cycle speeds for tightly synchronised electronic gearbox applications such as flying shear or time critical monitoring and control.

Heason Technology has used the Geo Brick LV on several multi-axis control system projects for customers that include Danfysik, the Danish particle accelerator equipment manufacturer, Diamond Light Source and CERN.
