CNC Mitsubishi Meldas FCA335CM

Post by miguelhdz » Mon May 22, 2017 11:48 pm

Sorry for my poor English:

I´m trying to install a slim SD Floppy Emulator in a Mazak CNC Milling machine. It will replace a Samsung SFD-321B floppy drive.
The machine needs to read a floppy disk named ¨MELDAS 335M MAZATROL M-32(SYSTEM)¨ at start up to boot up, but every time is more difficult to the machine to read it.
From I had read, the floppy drive runs at 360 rpm, so I bought a ¨GA-EG41MF-S2H" motherboard with floppy 3-mode suport.
The machine can format floppies for write, read and compare its macro and parameters, so I made a floppy disk dump on hxcfloppyemulator from a previously formatted and written floppy disk with machine macro/parameters.
And then I put this image renamed (DSKA0000.hfe) in the SD card, turn on the machine and then I do a ´Compare Parameters´ I got multiple alarms:

IOP Not Ready Error
IOP FDC Error

These alarms changes when I move the DIP switches, I tried every possible combination with no luck,
what am I doing wrong? Can I make a blank hfe image and format it on the machine?

Your HFE file is bad : There is no sector on most of the tracks. the dump has failed.

And if you want to test this image on a pc, you need to change/force the interface mode to IBM PC 1.44MB or 720KB into the cfg file. See the sd settings window.

the samsung SFD-321B(taken from cnc machine) doesnt work in the pc motherboard. motor runs but green led doesnt turn on.
but if I install another SFD-321B from an old compaq pc, it works on the pc motherboard but not in the machine.
so, whats the diference? jumpers settings?
here it´s a hi-res image:

LEFT
SFD-321B REV WT-05 from an old compaq pc
OPA1, DC, DS1 jumpered
RDY, OPB open
If I install it in the CNC, doesnt work (displays multiple alarms)
Installed in motherboard, it works (motor runs, green led flashes)

RIGHT
SFD-321B REV WT-04
DS0, RDY, OPB are jumpered
there is a capacitor left upper corner (C14)
In the cnc works, in pc doesnt
