ADLINK Technology (San Jose, CA) has released the PCI- 8254/PCI-8258 motion controllers that provide servo updates up to 20 KHz through hardware-based PID-FF control loop and secondorder filters, time-deterministic trajectory and velocity planning, comprehensive application functions, and diagnostic and control utilities. The program download function can execute up to eight individual tasks simultaneously, providing control performance in real time, and conserving CPU resources. The controllers also provide multidimensional interpolation, as in 3D linear/circular/spiral interpolation, for contouring applications in manufacturing industries such as laser engraving/cutting, glue dispensing, and others.They are equipped with MotionCreatorPro 2, a Windows-based application development software package. More applicable time-domain and frequency-domain diagnostic tools are integrated into this utility for auto-tuning, frequency response analysis, and motion and I/O data sampling. Sampling pages and graphic tools deliver real-time motion and I/O status, and conduct further motion flow analysis. The controllers support Microsoft® Windows® XP and Microsoft® Windows® 7 (32-bit) operating systems, and feature 32 additional onboard digital I/O channels.
