hello, i also need the 900 parameters for the OMC. Mine is the simple version with one cpu doing NC and PMC. theres no seperate PMC and Graphics card. Its a retrofit with no tool changer. I have the regular parameters but didnt know that extra buttons were needed for more parameters. I could also use an explaination of the Diagnostic parameters since those wernt backed up either. I guessed at some stuff and got the machine to home but many things dont work. Digital spindle is not talking to the control, single block wont turn off, tool unclamp non functional, and lube pump only works in manual mode. Ill PM my email for any info you can send my way. I called Fanuc and they said its all proprietary and they can send a teem to me to reprogram my machine. It didnt sound very economical.
