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.
