I. Overview

JANCD-FC230 is the motion control central sub-board of the Anson I80 system, also known as the MMON board. It is responsible for coordinating multi-axis motion instructions, performing interpolation calculations, and managing servo/axis data. It serves as the core bridge connecting the CPU board (FC200) and the servo/axis interface board (FC226), directly determining the motion control accuracy and response speed of the system.

III. Core Functions

Motion instruction coordination: Receives NC program instructions from the CPU board (FC200), distributes them to each servo/spindle axis group, and coordinates the timing of multiple axes.

High-speed interpolation calculation: Performs linear / circular / spline interpolation, generates smooth motion trajectories, supports forward ≥ 200 segments, improving processing accuracy.

Servo/spindle data management: Summarizes position, speed, and current feedback data of each axis, performs closed-loop calculation and returns it to the CPU, real-time monitoring of axis status.

Motion error compensation: Pitch compensation, clearance compensation, temperature compensation, correcting mechanical errors, improving positioning accuracy.

Multi-axis synchronous control: Supports electronic gearing, rigid tapping, multi-axis linkage synchronization, ensuring the synchronization of complex processing.

Fault monitoring and alarm: Real-time detection of axis synchronization abnormalities, interpolation timeout, feedback loss, with onboard LED alarm and system upload.
