Key Functions

1. Main CPU control: Executes CNC programs, coordinates multi-axis motion, and manages system logic.

2. Motion processing: Handles high-speed interpolation, servo loop control, and spindle motion commands.

3. System management: Oversees I/O, communication, safety interlocks, and diagnostic functions.

4. Data handling: Processes CNC parameters, macro programs, and machine feedback data.

5. Status monitoring: Provides LED indicators for power, run, alarm, and error codes.

Compatibility & Installation

• Compatible with Yasnac LX3 series CNC controllers (milling, turning, and machining centers).

• Installs in the dedicated CPU slot on the LX3 backplane (plug-in design).

• Not interchangeable with robot controller boards (e.g., NX100/XRC series) or other CNC models.

• Works with matching LX3 boards (I/O, servo, power supply modules).

Safety & Maintenance Notes

• Disconnect all power and wait for capacitor discharge before removal/installation.

• Use an ESD wristband to prevent static damage to components.

• Do not perform high-voltage withstand tests; semiconductors may be damaged.

• Regularly inspect connectors for dirt, corrosion, or poor contact.

• Repairs and replacements must be performed by qualified technicians.
