2. Product Overview

3. Core Functions

1. Multi-Axis Servo Control: Manages and controls the servo drives for multiple CNC machine axes (X, Y, Z, etc.).

2. Real-Time Signal Processing: Processes high-speed position and velocity feedback signals from encoders/resolvers.

3. Closed-Loop Control: Executes precise closed-loop PID control algorithms for position, speed, and torque.

4. Trajectory Interpolation: Performs complex path interpolation (linear, circular, helical) for smooth cutting motion.

5. Drive Command Output: Generates and transmits high-resolution command signals (voltage/pulse) to servo amplifiers.

6. Fault Detection & Protection: Monitors for servo faults (overcurrent, overload, overvoltage, position error) and triggers safety shutdowns.

7. System Bus Communication: Interfaces with the main CPU board and other I/O modules via the internal CNC system bus.

8. Isolation & Signal Conditioning: Provides optical isolation and signal filtering to ensure noise immunity in industrial environments.
