Classification and rapid identification of alarm codes
The alarm codes of Yaskawa robots are usually composed of letters and numbers, mainly divided into the following categories:
1. Servo system alarm (code starting with A): For example, A.010 represents overload alarm, and A.020 represents encoder abnormality
2. Mechanical system alarm (code starting with B): B.050 indicates joint over limit, B.100 is collision detection trigger
3. Control system alarm (code starting with C): C.004 indicates abnormal main power supply, C.020 indicates communication failure
4. Safety system alarm (code starting with D): D.002 emergency stop circuit disconnected, D.010 safety door openedTechnicians should develop the habit of first recording the complete alarm code, including accompanying auxiliary codes (numbers displayed in parentheses). For example, the '3' in 'A.010 (3)' may point to a specific joint position, which is crucial for subsequent diagnosiscanonRepair the Keyence laser scanner.

1. On site observation method:-Check if the robot is in an abnormal position or posture-Listen for any abnormal noise from the servo motor-Observe the status of the control cabinet indicator lights (power supply, servo, safety circuit, etc.)-Check if the cable connectors are loose, especially the cables at the joints
