Mitsubishi Service & Repair Forum
Based on my previous experience, the MITSUBISHI PD21B CNC module might be experiencing intermittent power loss resulting in frequent system freezing during operation. This could indicate a potential issue with the power supply or internal connections. Further inspection by a qualified technician is recommended to identify and address the root cause of the problem.
