ADLINK Technology introduced the PCI-8253 (three axes) and PCI-8256 (six axes) DSP-based servo motion controllers. The ADLINK PCI 8253/8256 use the latest digital signal processing technologies to provide a ±10 V analog motion controller with full closed-loop control, a PID plus feed-forward algorithm, and 20 MHz encoder input frequency. The PCI-8253/8256 not only provide general motion control functions, but also support comprehensive and application-specific functions. The PCI-8253 and PCI-8256 are available now for a list price of $1,329 and $2,129, respectively.

The PCI-8253/8256 are able to provide advanced, flexible, and comprehensive motion functions that cannot be achieved through ASIC-based solutions. Such functions include multiple dimension interpolation and high-speed position comparison. All motion profile algorithms are developed by ADLINK and implemented on the DSP. As a result, application-specific functions can be custom develop for customers.
The PCI-8253 and PCI-8256 provide higher motion control performance with a fast encoder input frequency up to 20 MHz. In addition, the hardware-based high-speed position comparison and trigger output speed of up to 1 MHz further make the PCI-8253/8256 ideal for AOI applications. The PCI-8253 and PCI-8256 also offer a point table that supports over 5,000 points for each axis (ideal for contouring applications).
Setup and deployment of the PCI- 8253/8256 are greatly simplified through ADLINK’s MotionCreatorPro 2, a user-friendly Windows-based application development software package. Axis servo gains (PID plus feed-forward gain) and be easily tuned through this tool, which greatly reduces the amount of effort spent on gain tuning. A sampling window also provides a real-time display of the motion data enabling simpler integration of axis parameters, PID gain, and other on-the-fly changes.
The PCI-8253 and PCI-8256 DSP-based servo motion controllers are ideal for automated optical inspection (AOI), gantry, and manufacturing machine applications. They offer complete compatibility with all the top third-party servo drivers in the market.
