Designed for Complex Motion Control Multi-axis Coordination Capabilities of ODOT's DU03 Series PLC

Against the backdrop of industrial upgrading in sectors such as high-end equipment manufacturing, new energy, and semiconductors, production equipment now demands unprecedented precision, speed, and multi-axis coordination in motion control. Complex trajectory planning, high synchronization, and large-scale axis group management have emerged as core technical challenges in achieving efficient and flexible production.

ODOT Automation's DU03 Series Plc is a high-end control platform developed precisely for such complex scenarios. Built upon the innovative AIOSYS programming software platform, the series complies with both IEC 61131-3 and IEC 61499 standards. It supports multi-language programming including LD, ST, and C, offers web-based programming capabilities, and achieves full autonomy and controllability in both software and hardware.

As a core controller specifically engineered for complex motion control, the DU03 Series delivers a robust multi-axis coordination solution. The system supports up to 128 motion control axes and integrates a comprehensive suite of advanced motion control functions. These encompass core algorithms such as speed control, position control, jog control, electronic gearing, electronic cam, linear interpolation, and 2D/3D circular interpolation. By supporting mainstream industrial real-time Ethernet Protocols like EtherCAT and PROFINET, it enables microsecond-level precise synchronization, ensuring coordinated multi-axis movement and high-speed response to meet requirements ranging from simple positioning to complex trajectory machining across all application scenarios.

The entire product series features hardware localization and software autonomy/controllability. It is supported by the unified AIOSYS programming platform, offers a rich set of communication protocols, and enables distributed control.

In terms of motion control architecture, the DU03 Series PLC supports coordinated control of both real and virtual axes. Real axes connect to physical servo drives via the EtherCAT bus for high-precision, highly synchronized real-time control. Virtual axes are generated internally within the AIOSYS software, requiring no physical motors, and are commonly used for motion simulation, as synchronization masters, or for auxiliary trajectory planning. This architecture significantly reduces system wiring complexity and greatly enhances flexibility in motion program planning and system expansion. Models within the series offer gradients in the number of motion control axes, expansion capabilities, and network configurations to suit applications of varying scale and complexity.
