Part Number: 1X00416H01 (Model: WH5-2FF)
Part Number: A911-2160 (Model: OSP7000 SVP Board, Alternate P/N: E4809-045-158)
Brand: Okuma Corporation
Product Category: CNC Servo Vector Processing (SVP) Control Board (OSP7000 Series)
Product Series: Okuma OSP7000 CNC System Peripheral Board (Compatible with OSP7000 CNC Systems)
Core Application: Dedicated to Okuma OSP7000 CNC systems, serving as the core servo vector processing board for high-precision motion control in CNC machine tools (milling, turning, multi-axis machining centers). Responsible for servo loop calculation, vector control algorithm execution, real-time position/speed feedback processing, and seamless communication with the main CPU board and servo drives. Ensures high dynamic response and positioning accuracy for machine tool axes, essential for complex contour machining and high-speed cutting applications.
Core Features: High-speed 32-bit servo vector processing; integrated position/speed/torque control loops; support for multi-axis interpolation (up to 4 axes simultaneous control); built-in encoder feedback interface (1Vpp sine/cosine, incremental); real-time servo parameter tuning and optimization; compatibility with Okuma proprietary servo drives (BLII series); built-in diagnostic functions for servo system faults; hot-swap capable in some configurations to minimize downtime; industrial-grade design for harsh machine shop environments.
