4-Axis, Isolated Stepper Motion Controller Device—The PCI-7390 is a position (pulse) motion controller with isolation designed for use with drives that accept position (p-) command mode or step (pulse) command input. The PCI-7390 provides fully programmable motion control for up to four independent or coordinated axes of motion. 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.
