Description
1. Product Overview
AJINEXTEK PCIE‑R0805‑ECAT is a high‑performance 8‑axis EtherCAT motion‑control PCIe card developed by AJINEXTEK (South Korea). Designed for high‑end multi‑axis coordinated automation systems, it serves as the core bus master unit for IPC‑based motion‑control platforms. Equipped with a high‑speed standard PCIe interface and proven real‑time EtherCAT industrial Ethernet protocol, this card can synchronously manage multi‑axis servo and stepper drives, and support high‑precision interpolation motion, coordinated linkage and flexible speed regulation. It features strong real‑time performance, excellent synchronization accuracy, flexible bus expandability, outstanding anti‑interference capability and wide‑ranging system compatibility. A single card supports up to 8‑axis independent motion control, enabling convenient construction of small‑to‑medium‑size multi‑axis automation systems. It effectively simplifies wiring, reduces system redundancy and improves motion accuracy and operational stability. Widely adopted for precision automated machinery, custom‑built smart production lines, semiconductor‑processing equipment and precision inspection instruments, it is a preferred bus‑based motion‑control card for industrial multi‑axis coordinated applications.
2. Core Functions
High‑precision 8‑axis independent & coordinated control: One single card supports synchronous control of up to 8 servo/stepper motors. It realizes single‑axis point‑to‑point motion, multi‑axis linear interpolation, circular interpolation, electronic cam, synchronous following and other sophisticated motion sequences. Each axis delivers high‑control accuracy and ultra‑low response latency, fully meeting automation requirements for precision machining, high‑accuracy positioning and high‑speed multi‑axis coordination.
Standard EtherCAT real‑time bus communication: Built‑in industrial‑grade EtherCAT real‑time Ethernet bus provides microsecond‑level transmission latency and minimal synchronization jitter. It stably connects all EtherCAT‑compliant slave devices and supports scalable axis expansion and digital‑I/O extension. Flexible bus topologies make it suitable for various distributed automation architectures.
High‑speed PCIe data exchange: Communication via standard PCIe slot delivers higher transmission bandwidth and faster data throughput compared with legacy PCI buses. It rapidly uploads motion status, axis‑position data and alarm information while receiving upper‑level control commands, completely eliminating data congestion and command lag in multi‑axis control.
Integrated rich motion‑process logic: An embedded dedicated motion‑algorithm library provides full‑featured functions including homing, limit protection, soft start‑stop, speed switching, position compensation and trajectory pre‑planning. It can be quickly adapted to bonding, cutting, handling, inspection and other automated processes, greatly shortening equipment programming cycles.
Comprehensive fault‑diagnosis and safety protection: It continuously monitors bus communication status, axis faults, limit anomalies, overload alarms and communication interruptions. Fault codes and operation logs are automatically stored for fast fault localization. Dual protection via software and hardware limit switches effectively prevents risks such as mechanical collision, over‑travel and uncontrolled motion.
- Light‑weight, easy‑to‑integrate and long‑term stable operation: The compact, highly‑integrated board fits standard PCIe slots in industrial PCs, enabling simple installation and streamlined wiring that reduces field‑wiring failures. The industrial‑reinforced hardware is resistant to electromagnetic interference and vibration. It supports 7×24‑hour non‑stop operation with no long‑term drift of motion‑control accuracy and high system reliability.

4. Working Principle
The AJINEXTEK PCIE‑R0805‑ECAT motion‑control card executes a full‑cycle control workflow: upper‑level command parsing → trajectory calculation via motion algorithm → synchronous output over EtherCAT bus → closed‑loop feedback of axis status → real‑time fault protection. Motion‑control commands sent from host software are received by the card through the PCIe interface. Its high‑speed motion‑calculation unit performs real‑time computation and trajectory planning for position, velocity, interpolation and other parameters to generate precise motion instructions. Control commands are transmitted synchronously to servo and stepper drives over the EtherCAT bus to drive motors to complete accurate movements. Axis‑position, speed and status feedback data from bus‑connected devices are continuously sampled to dynamically adjust trajectories and output values, forming high‑precision closed‑loop control. During runtime, bus communication, equipment conditions and limit signals are monitored constantly. Once an abnormality is detected, protection routines and alarm triggers are activated with fault data recorded, ensuring high‑speed, precise, stable and safe operation of the multi‑axis coordinated system.
5. System‑Architecture Compatibility
Developed based on standard PCIe and EtherCAT protocols, this card offers excellent system adaptability. It is plug‑and‑play with standard PCIe slots on most industrial PCs (IPCs), requiring no complex hardware configuration and supporting upgrades of both new and legacy automation equipment. It is fully compatible with third‑party EtherCAT‑compliant servo drives, stepper drives and remote I/O modules without custom adaptation programs. Multiple cards can be installed in parallel to expand the total number of controlled axes to 16 or more without modifying the core control framework. A mature SDK library supports mainstream programming languages including C, C++, C#, VB and LabVIEW, enabling seamless integration with various host‑level automation software and fitting the control architecture of most intelligent machinery and automated production lines.
6. Application Scenarios
This product targets high‑end precision multi‑axis coordinated automation under demanding industrial conditions requiring high accuracy, high speed, tight synchronization and unattended continuous operation. Typical equipment includes semiconductor precision‑processing machines, automated bonding systems, high‑speed cutting machines, precision inspection instruments, custom‑built smart assembly lines and multi‑axis manipulators. It is widely deployed in 3C‑electronics manufacturing, precision‑component machining, new‑energy‑equipment assembly, automated material‑sorting and precision metrology. Benefiting from high‑precision 8‑axis coordination, simplified bus wiring, fast response, stable performance and convenient development, it improves equipment motion accuracy and production efficiency while reducing failure rates and maintenance costs. It serves as a preferred core motion‑control card for small‑to‑medium multi‑axis automation systems.
