Hello, I bought an ABB IRB 2000 MK95 with S3 controller . I had to repair electronically drive board YTE no2 and bypass PTC on third wrist in order to get inline the system. A limit switch has to be bypassed too-for now, since unit had two ML-160 tables, a carry system ,optical fences and remote start unit. Main problem occur now : programs can't be read from floppy unit [ 3 " ],error 30 is stable even I replace the unit with several 3 " units, all tested and running.
Power supply checked : 5.02 V and 11.98 V. Another cable for data I used and gave same error. I have a last hope : beside the floppy connector ( on CPU board ) seem to be two jumpers. There is any description somewhere about those jumpers? Test mode: on CPU the choose of TEST mode gave ability to access disk. There a cleaning can be performed. If I do the cleaning and then repeat Disk -From Disk - Error 28 pop -up. If I clean the error , the following message pup-up : Input 32769 = 241. After 'first' 28 error, on the next attempt to read disk- next error is 508- Disk Memory Fault error 30. Should I consider that Non-Dos format of disk make very sensitive the data to be read -therefore disk head should be cleaned often? [ I do received a diskette with a label : - prog 999 cut -prog 2002 side weld// then I assume system was operating normally back time ] Thank you, Vio
