ADLINK Announces Advanced DSP-Based Servo Motion Controllers



The PCI-8253 and PCI-8256 provide fully closed-loop control with high accuracy and fast response time for AOI, gantry, and contouring applications

October 27, 2009, San Jose, Calif - ADLINK Technology Inc., a leading global provider of measurement and automation products, announced the release of their most advanced DSP-based servo motion controllers, the PCI-8253 (three axes) and PCI-8256 (six axes). 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, 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 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.

By incorporating a digital signal processor (DSP), 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. Therefore, application-specific functions can be custom develop for customers.

By incorporating FPGA technology, the PCI-8253 and PCI-8256 provide higher motion control performance by 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.

"Customers will greatly benefit from gantry control with dynamic error compensation, as the real-time feature of the DSP and the control loop provides superior control of large stage movement in TFT/LCD, PCB, and machine tool industries," stated Ethan Huang, Senior Product Director at ADLINK. "The PCI-8253 and PCI-8256 also offer basic G-code support which make these controllers ideal for machine tool and manufacturing machine 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.
