Based on over ten years of experience in developing PC-based motion controllers, ADLINK designed the PCI-8253/8256 to take full advantage of the latest digital signal processing technologies to provide a ±10 V analog motion controller with full-closed loop control with PID plus feed-forward and 20 MHz encoder input frequency. The PCI-8253/8256 not only provide general motion control, but also support comprehensive and application-specific functions ideal for automated optical inspection (AOI), gantry, and manufacturing machine applications, as well as complete compatibility with all the top third-party servo drivers in the market.
Product Highlights
  • High-Speed Position Comparison & Trigger Output
    The PCI-8253/8256 provide higher motion control performance by a fast encoder input frequency up to 20 MHz and also provide hardware-based high-speed position comparison and trigger output speed of up to 1 MHz.
  • Blend Motion
    To ensure smooth movement along the path, the PCI-8253/8256 incorporate blend motion which looks several points ahead and combines splining motion for continuous and smooth velocity movement. If more than one move is specified in succession with no pause in between, the first movement will blend into the second with the same type of controlled acceleration as is done to and from a stop.
  • Point-Table mixed Motion & I/O Control
    The PCI-8253/8256 provide higher motion control performance by a fast encoder input frequency up to 20 MHz and also provide hardware-based high-speed position comparison and trigger output speed of up to 1 MHz.
  • Dynamic Gantry Error Compensation
    Gantry control with dynamic error compensation is part of the real-time feature of the PCI-8253/8256, providing superior control of large stage movement in TFT/LCD, PCB, and machine tool industries.
