The Delta Tau ACC-24E2S-DB is a high-performance servo axis interface board designed for Delta Tau’s Power PMAC and Turbo PMAC motion control platforms. This critical component provides robust connectivity between controllers and servo drives in precision motion systems, featuring dual-channel SERDES (Serializer/Deserializer) technology for ultra-low-latency communication. The ACC-24E2S-DB supports up to 8 axes of motion with its advanced FPGA-based signal processing, handling high-resolution feedback devices including absolute encoders (Biss-C, EnDat 2.2), resolvers, and analog inputs at update rates ≤ 250 µs. Its rugged design integrates galvanic isolation (1500V) on all I/O lines to protect sensitive electronics from ground loops and voltage spikes in industrial environments.
Engineered for complex multi-axis applications, the Delta Tau ACC-24E2S-DB implements Delta Tau’s proprietary “MACRO” (Motion and Control Ring Optical) interface, enabling deterministic communication with Delta Tau Geo MACRO drives via fiber optics. The board’s 32-bit RISC processor executes real-time servo algorithms with hardware-level jerk control and adaptive filtering. With dual DB-25 connectors for feedback devices and dedicated marker input channels, the ACC-24E2S-DB delivers the precision required for semiconductor lithography, aerospace test rigs, and high-speed robotics.

Main Features and Advantages
Deterministic motion control: The Delta Tau ACC-24E2S-DB achieves ≤250 ns jitter with hardware-level trajectory planning, enabling nanometer-precision positioning. Its SERDES interfaces decode high-speed serial encoders (up to 16 MHz) without CPU overhead, critical for wafer steppers and diamond turning machines.
Advanced signal integrity: Triple-buffered input channels eliminate data loss during high-acceleration moves. Built-in sub-count interpolation (0.001x resolution) enhances positioning accuracy, while adaptive notch filters suppress mechanical resonances in robotic arms.
Seamless integration: Native compatibility with Delta Tau’s Power PMAC IDE software simplifies commissioning. The board’s dual MACRO rings support daisy-chained communication with Geo MACRO drives (e.g., ACC-84E), enabling synchronized multi-axis coordination. Galvanic isolation protects against 1500V surges in EDM and welding environments.
Application Field
The Delta Tau ACC-24E2S-DB dominates ultra-precision motion systems. In semiconductor manufacturing, it controls wafer stages in ASML lithography tools and wire bonders, leveraging nanoradian encoder resolution. Aerospace test stands use its resolver interfaces for flight simulator motion bases with 0.001° repeatability.
For medical device production, the board synchronizes laser cutting heads in stent manufacturing machines. Robotics integrators deploy it for delta robot pick-and-place systems operating at >200 cycles/minute. Its SERDES capability enables absolute position feedback in CNC gear grinders without battery backups.

Installation and Maintenance
Pre-installation preparation: Verify Power PMAC firmware compatibility (V2.5+). Discharge static electricity before handling the ACC-24E2S-DB. Use shielded twisted-pair cables for encoder connections with drain wires grounded at one end. Configure SERDES protocols in Power PMAC IDE before power-up.
Maintenance recommendations: Monitor FPGA temperature via Power PMAC diagnostics monthly. Clean DB-25 contacts annually with contact cleaner. Update FPGA firmware during planned downtime using Delta Tau’s FLS utility. Avoid bending ribbon cables during reinstallation.
