HOW TO MOVE WORK OFFSET IN A HEIDENHAIN CONTROLLED VERICUT MACHINE

In a Fanuc control we use #5202 or G10L2P0Z to shift an offset.
In the Heidenhain control # is replaced with Q and our machine uses Datum 1 , Datum 2 ...... and so on
I just can't find the Q value to shift????

We move the part down a little but we need to move the Datum to follow the part.
I hope someone understands this and can assist me.
Thanks

Re: HOW TO MOVE WORK OFFSET IN A HEIDENHAIN CONTROLLED VERICUT MACHINE

In Heidenhain, to alter system parameters you use the SYSTEM WRITE function and to do this on the machine you need a code number to unlock the SYSTEM WRITE function. What version of Heidenhain are you running? There are significant differences between iTNC530 and TNC640. To see a list of available parameters, refer to the SYSTEM READ definition in the PROGRAMMING Q PARAMETERS section of your (conversational) manual.

Here is some sample code I use for resetting the C axis offset (iTNC530)

;READ C AXIS REF POSITION
FN 18: SYSREAD Q1905 = ID240 NR1 IDX6
FN 17: SYSWRITE ID 503 NR42 IDX6 =-Q1905
CYCL DEF 247 DATUM SETTING ~
Q339=+42   ;DATUM NUMBER
