Industrial Machine Intelligent Control System AOS

Pulse Motion Control Card

AOS pulse motion control card is a motion control unit based on PCI bus for stepper motor and servo motor control. It takes high-performance DSP and FPGA as co-processors for path planning. It supports high-speed point positioning and continuous trajectory motion control. It has various functions such as multi-axis synchronized motion control, interpolation control, PSO, control parameters setting etc., and provides various library files under VC, VB, C# and other development environments for users’ secondary development.

  • 4 or 8-axis motion control

  • DSP high-speed motion planning

  • FPGA for multi-axis synchronized control

  • Motion planning of Trap, Jog and Gear

  • Motion planning of Follow, TP and PVT

  • 2-axis linear and circular interpolation, 3- and 4-axis linear interpolation and spatial spiral interpolation

  • Creation of multiple interpolation coordinate systems simultaneously

  • With look-ahead preprocessing algorithm, backlash compensation and pitch error compensation
