hi friends.
we have problems on our cincinnati acramatic 2100 machine.
first thing is ;
we got "alarm 40-33 output/fuse failure on APC rack 0"
there are some informations that says bad RT-board causes this error.
but I tried two RT-board
and I tried both RT-board seperately with connecting psu,vga card, and a screen.both of them seems good.bios settings are ok.
bridge board led does not give any error with both two boards.
diagnostic screen shows all boards "passed"
I/O board and I/O connections seems ok.
second thing is ;
system has vickers servo drive and vickersvector spindle drive and this drives connected with two cables to RT-board com ports.
when we want to verify / download drive parameters from service menu, we got an error on all axis " communication hardware not present "
according to an information at one of manual, these drive parameter verify/download process uses this two cable
cables are ok, I tried all com port options in rt-board bios settings.
but still we are not able to communicate with drives.
I attached some pictures, please look at these.
