Need Help!- oma parameters

[monaro mike]

G,day from Mike in Australia, having used mainly mazak machines in my toolmaking career my knowledge of fanuc and g code programing is limited.
I have a 1987 leadwell mcvo which ive only ever done basic iso programs on, so i need help occasionally.
What i need to know is which parameter needs changing to stop the relative coordinates from resetting when m/c is sent to home posn. as i wish to use the tool teach function etc and whenever you change a tool in mdi after zeroing z on longest tool the measured posn. is lost as it goes to home.
Also i would like to know which parameter enables the automatic insertion of sequence no.s , parameter no.550 seqinc (number increment value in automatic insertion of sequence no. setting range 0 to 9999 ) is set to 5 which is what i want.
Fanuc manuals are written in japlish as you all know so if ive missed something while reading it i know i,m not the first and definately not the last who wants to burn it ! thanks any help appreciated cheers.

Please try changing prm. 2.1 the description says: THE RELATIVE COORDINATE VALUE IS PRESET WHEN THE COORDINTAE SYSTEM IS SET. I hope this is what you need.
