Elmo’s Gantry solution is a breakthrough alternative to the traditional Gantry systems where motion controllers rely on complex, centralized motion control architecture to handle high-dynamic MIMO cross-coupled feedback technology. Elmo achieves superior performance with its unique distributed motion control. Accompanied by innovative servo tuning tools, Gantry control by Elmo is the best overall cost and performance solution for high-precision Gantry and XY Planar systems.
The Elmo approach provides precise control with only two, mount it anywhere, servo drives operating as one integrated unit. There is no need for a bulky, dedicated motion controller or extra moving cables. Employing super-fast MIMO communications, one Gold servo drive is configured as the master (X1) with a second drive (slave, X2) following its lead and sending feedback data. The Elmo Application Studio (EAS) software guides you through the entire implementation process, providing drive configuration, safety and protections, system identification and controller design in an easy-to-use GUI format.
EtherCAT/CANopen Gantry Solution
Elmo's approach is not only suitable for dual-axis Gantries, but is easily extended to full 4-axis planar control and other complex applications. Multi-axis performance is realized by merely adding Elmo's Gold Maestro motion controller to control up to 100 axes via EtherCAT or CANopen, saving critical cables and improving reliability.
