  • MotionCreatorPro 2

    • MotionCreatorPro 2 is a Windows-based application development software package included with the PCI-8253/PCI-8256. MotionCreatorPro 2 is useful for debugging a motion control system during the design phase of a project. Anon-screen display lists all installed axes information and I/O signal status of the PCI-8253/PCI-8256. By using this utility, you can easy tune the axis parameter servo gain (PID plus feed forward gain) reducing the efforts on gain tuning. Furthermore, the sampling windows makes more accurate in motion data analysis, moreover, integrates with axis parameter and PID gain on-the-fly change, thus, the PCI-8253/PCI-8256 provides precise positioning control with less effort.
