3. High speed position comparison and triggering (Pulsar Input)
The board provides 1-channel Pulsar Input, which can be configured as CW/CCW pulse direction or AB phase encoder input (supporting 1x/2x/4x multiplication), with a maximum input frequency of 1MHz. This interface can be used to connect external encoders or grating rulers, achieve full closed-loop position feedback, or serve as a high-speed position comparison trigger source, immediately triggering the camera to take photos or laser to emit light when reaching the designated position, ensuring detection accuracy.
Hardware interface and isolation protection
1. Isolate digital I/O
Onboard 4-channel isolated digital input and 4-channel isolated digital output (typical 24V, input NPN leakage type, output current capacity 90mA), can be used to connect emergency stop buttons, limit switches, reset signals, indicator lights, etc. The dedicated emergency stop input (EMG) is a hardware level fast response channel that does not rely on software scanning cycles. When the input signal is triggered, the control card immediately interrupts the movement of all axes and outputs a brake signal to ensure the safety of equipment and personnel.
2. Pulse input configuration
Pulsar input supports 5V or 24V levels (typical 24V), source type input, and can be directly connected to differential or single ended encoder signals. This input can be used as an auxiliary encoder channel for spindle synchronization or flying saw cutting applications.
3. Environment and Certification
The working temperature is 0-60 ℃, the storage temperature is -20~80 ℃, the humidity is 5-95% without condensation, and it complies with CE/FCC and RoHS standards. PCIe gold finger connectors ensure reliable contact and are suitable for long-term continuous operation in industrial sites.

Software Ecology and Development Convenience
1. Operating system and programming language support
Supports Windows 7/10 32/64 bit systems, provides APS libraries, and is compatible with Visual Studio C #, VB.net, and C++development environments. Developers can quickly access interfaces such as motion control, I/O read/write, interpolation startup, parameter configuration, etc., greatly reducing the development cycle.
2. MotionCreatorPro ² Configuration Tool
ADLINK provides dedicated MotionCreatorPro ² upper computer software with the following functions:
EtherCAT bus scan: automatically detects and identifies all connected slave devices, displaying device models and topology.
Axis parameter configuration: Set servo driver loop gain, acceleration and deceleration time, soft limit, electronic gear ratio, etc.
Sports testing: supports single axis point motion, zeroing, relative positioning, absolute positioning, and real-time monitoring of position, speed, and torque curves.
Program download and debugging: The written motion program can be downloaded to the control card and debugged online for single step execution, breakpoints, and other functions.
I/O monitoring and control: Real time viewing of DI status and forced DO output for easy on-site debugging.
This tool simplifies the system debugging process, allowing engineers to complete basic verification without writing a single line of code, greatly improving engineering efficiency.
3. Offline simulation and online diagnosis
The APS library supports offline simulation mode, allowing verification of motion logic and parameters without actual hardware, reducing development risks. At the same time, it provides rich error diagnosis interfaces, including EtherCAT communication abnormalities, slave loss, and tracking error exceeding limits, to help quickly locate faults.
Detailed explanation of typical application scenarios
1. Semiconductor packaging equipment (Die Bonder)
In multi chip mounting equipment, up to 20 axes such as XY θ platform, ejector pin mechanism, nozzle Z-axis, and feeding track need to be controlled. PCIe-8338 can coordinate these axes simultaneously to achieve high-speed and high-precision positioning. The 250 μ s cycle ensures the smoothness of each motion point, while the Pulsar input can be connected to a grating ruler to achieve position closed-loop, ensuring a mounting accuracy of ± 5 μ m. The event triggering function can immediately activate the dispensing or curing laser upon reaching the set position, improving output efficiency.
2. Electronic assembly automation (PCBA plugin machine)
The plug-in machine requires inserting electronic components into circuit board holes, involving multiple axis coordination such as X, Y, Z, rotation, and clamping. By using PCIe-8334, 32 axis control can be achieved while managing multiple plug-in heads working in parallel. 3D spiral interpolation can be used for oblique insertion of components to reduce hole damage. The isolation I/O on the board is directly connected to the feeding sensor, in place detection, shortage alarm, etc., reducing external PLC dependence.
3. Multi axis laser processing platform
Laser cutting or welding equipment usually requires XY galvanometers, Z-axis focusing, rotation axis, feeding axis, etc., and requires high speed and high precision. The point table function of PCIe-833x can generate complex trajectories in advance, which can be autonomously executed by the controller to ensure smooth changes in speed and acceleration and avoid uneven laser energy. Meanwhile, digital I/O can control laser switches, blowing valves, etc., achieving process integration.
