When an industrial robot stops due to a fault code, every second counts. Production delays, troubleshooting uncertainty, and unexpected repair costs can quickly escalate.
This Industrial Robot Fault Codes Library is designed to help engineers, technicians, and maintenance teams quickly identify, understand, and resolve robot errors across major brands like ABB, FANUC, KUKA, and Yaskawa.
Industrial robot fault codes are diagnostic messages generated by the controller when the system detects abnormal behavior.
These errors typically relate to:
Each manufacturer uses a different fault structure:
Understanding these codes is the first step toward fast and accurate troubleshooting.
