The National Instruments PCI-7390 is a position (pulse) command stepper motion controller with isolation designed for use with drives that accept position (p-) command mode or step (pulse) command input. The NI PCI-7390 has accessories specifically designed for direct connectivity to Yaskawa Sigma II, Mitsubishi MR-J2S, and Panasonic Minas A drives. The PCI-7390 provides fully programmable motion control for up to four independent or coordinated axes of motion. It features dedicated motion I/O for limit and home switches and additional I/O for general-purpose functions such as in-position, inhibit input/drive alarm, and servo ready.You can use the PCI-7390 controller for point-to-point and straight-line vector moves. The PCI-7390 also performs arbitrary and complex motion trajectories through circular, spherical, or helical interpolation. The PCI-7390 uses quadrature encoders for position and velocity feedback (closed-loop only) and provides advanced encoder functions such as trigger (position capture) and breakpoint (position compare).
