DSP-based Analog Motion Controllers
The PCI-8253/PCI-8256 controllers combine a 250 MHz 32-bit MIPS processor, 12,000 logic element FPGA (Field Programmable Gate Array), I/O buffering circuitry, ADLINK softmotion, and motion control characterization software to control the position/velocity of as many as six ¡Ó10 V analog command servo axes.
ADLINK Softmotion
PCI-8253/PCI-8256 leverages ADLINK softmotion technology, 250 MHz DSP and 20 MHz encoder rate to meet faster servo update rate up to 50 £gs/axis and control requirement in real application. PCI-8253/PCI-8256 not only realizes the gantry control with closed-loop and error handling, but also adopts the feed-forward gain to reduce speed profile following error to meet precise velocity and position control.
