Description

The DELTA TAU UMAC 465CPU is a high-end motion controller module from the Power PMAC (Programmable Multi-Axis Controller) family, designed for the most demanding industrial automation applications. Housed in a compact 3U rack-mount chassis as part of the UMAC (Universal Motion and Automation Controller) system, the 465CPU combines a dual-core ARM Cortex-A9 processor running a real-time Linux OS with a powerful Xilinx Kintex-7 FPGA. This hybrid architecture enables simultaneous execution of complex kinematic calculations, IEC 61131-3 PLC logic, EtherCAT master control, and custom real-time algorithms—all with deterministic sub-microsecond servo loop performance. Ideal for semiconductor equipment, precision machining, robotics, and scientific instrumentation, the UMAC 465CPU delivers unmatched flexibility, speed, and integration.

Application Scenarios

At a leading EUV lithography tool manufacturer, engineers needed to synchronize 48 axes of motion—including wafer stage, reticle stage, and mirror adjusters—with nanometer-level path accuracy and jitter below 50 ns. The legacy Turbo PMAC system could not meet the bandwidth requirements. They migrated to the DELTA TAU UMAC 465CPU, leveraging its FPGA-based servo loops running at 62.5 kHz and built-in EtherCAT master to directly control Beckhoff drives. Using custom C routines in the real-time Linux environment, they implemented feedforward compensation for thermal drift in real time. The result: overlay error reduced by 60%, and throughput increased by 22%. In this application, the UMAC 465CPU wasn’t just a controller—it was the enabler of next-generation chip manufacturing.

Technical Principles and Innovative Values

Innovation Point 1: True Hardware/Software Co-Processing

Time-critical tasks (e.g., PID, trajectory interpolation) run in the FPGA for nanosecond determinism, while non-critical tasks (HMI, data logging, network services) run on the Linux CPU—maximizing resource efficiency.

Innovation Point 2: Native EtherCAT Master in FPGA

Unlike software-based masters, the UMAC 465CPU implements the entire EtherCAT state machine and datagram processing in hardware—achieving <1 µs cycle jitter even at 1 kHz update rates.

Innovation Point 3: Open Linux Environment with Real-Time Guarantees

Developers can install standard Linux packages (e.g., SSH, NTP, Docker) while maintaining hard real-time performance—enabling edge AI, OPC UA servers, or cloud telemetry without compromising motion control.

Innovation Point 4: Seamless Migration from Turbo PMAC

Backward-compatible command syntax (e.g., Ixx, Mxx variables) allows rapid porting of legacy applications, while new Power PMAC features (C programs, structs, pointers) unlock modern software practices.

Application Cases and Industry Value

Medical Robotics: A surgical robot developer used the UMAC 465CPU to coordinate 7 DOF arms with force feedback, achieving ISO 13485-compliant motion safety via dual-channel torque monitoring in the FPGA.

Additive Manufacturing: A metal 3D printer OEM synchronized laser galvo scanners, powder recoaters, and Z-stage using Power PMAC kinematic libraries—reducing layer misalignment by 90%.

Particle Accelerator: At a national lab, the 465CPU controlled 120 magnet power supplies with 10 ppm current stability, using custom FPGA filters to reject grid harmonics.

Installation, Maintenance, and Full-Cycle Support

The UMAC 465CPU installs into a UMAC 3U chassis and connects via Ethernet for configuration. Initial setup uses the Power PMAC IDE to assign IP, load firmware, and deploy user programs. All motion parameters, PLC logic, and C applications are stored persistently in eMMC.

For maintenance:

Real-time status is accessible via built-in web server (no software needed).

Remote SSH allows log inspection, file transfer, and service restarts.

FPGA bitfiles and OS images can be updated in-field via microSD or TFTP.

Every UMAC 465CPU we supply undergoes full functional validation:
