Introduction to FANUC Alarms

Common FANUC alarm Codes are critical alerts in CNC machinery, signaling issues that require immediate attention. Properly understanding and addressing these alarms is essential to maintaining optimal machine performance and avoiding costly downtime.

Categories of FANUC Alarms

1. System Alarms

System alarms indicate issues with the CNC system itself. These could range from memory problems to system initialization failures.

2. Servo Alarms

Servo alarms point to issues within the servo drive or motor, such as overloading, overheating, or communication errors.

3. Spindle Alarms

Spindle alarms are related to the spindle drive or motor, indicating problems like over-speed, over-current, or cooling failures.

4. Overtravel Alarms

Overtravel alarms occur when the machine exceeds its defined travel limits, potentially causing mechanical damage.

Common FANUC Alarms Codes and Their Solutions

System Alarms

  • Alarm 900: RAM Parity Error
