Two-Axis ControllerCX 1102 two-axis unwind/dancer/wind controller calculates diameters automatically for constant line speed. The controller uses axle drive motors and encoders; has built-in automated dancer load/unload sequences; works with AC, DC, vector, or servo drives; and uses a moving dancer trim signal to trim either axle. The system includes a multi-line display, a built-in PLC, signal isolation, menu and help screens.
