Hello, I have problem with deckel FP3a controler CNC2102 MNP51 board - display stuck o 00 and not responce to keyboard. I need eproms dump from MNP51 or NMP50 from CNC2101 to test system.
Error 00 is emergency off or PLC undervoltage. Check cables and connectors and the power supply. There is no need to fiddle around with the EPROMs.
I repair plc board 5v and -15v section. Now plc lamp "?" go off after Ein and i can switch on collant pump and spindle breaker. Undervoltage - i have schematic but power section are mising. I dont understand communication between plc and processor board. 00 is always on, if i remove all axis cards, ram card and serial communication card is still on. I change all 6821 I/O chip and check cables. On CRT i have only 00 and nothing else. I check all ram chip on beeprog programer. My idea is CPU schow 00 and stuck on error in code but its only idea.
