Why does the RDC8445S controller automatically reset to the origin?

My CO2 laser cutting machine uses the RDC8445S control system. Today, I found an abnormality while operating it. Every time the processing program starts, the originally set processing point will automatically reset to the equipment origin. Whether it is continuous machining or individual workpiece operation, the system will forcibly return to the starting coordinates at the moment of startup, causing the machining path to be interrupted. What is the reason for this? Thank you in advance for your suggestions.
