[Cause]
PowerWaveErrorCode No.56 occurred. A communication error occurred between the main control circuit board and circuit breaker board. High-frequency noise or noise on the power line may have caused it.
[Countermeasure]
Check the communication cable between the circuit boards. Separate the welding equipment from high-frequency noise sources. If the error occurs when triggered, replace the circuit breaker board. Before performing any other operations (power-off or jogging) after this alarm occurs, use the abnormal-state recording function ("Abnormal State Record" in the auxiliary menu) to obtain an image backup and contact the service center. If that function cannot be used, record the conditions and operating steps up to the alarm, obtain an image backup, and contact the service center.
