How to set/adjust Z0 in G30??

[CNC Viking]

Hi,

My Meldas 520 AM use G30 in the Tool Change program and in a special Tool Length Measuring program.

Example:
G91G30Z0M19

I would like to adjust Z0 as I find it a little too low for my ATC. The spindle's tool clamping/unclamping movement pushes (flexes) my umbrella type tool magazine downwards when changing tool and I don't like that at all.

Can someone explain where in the control's menu's one can set or adjust all G30 parameters for 2:nd, 3:rd and 4:th Reference Points.

Come on guys!

There must be lot of people here that can do this blind folded.

Any chance of help?? I really need to fix this.

OK, I finally got it.
Chippy helped me in another thread. He told me to look for the ZP-RTN tab in MACHINE PARAMETERS.

Procedure to set, or modify, the 2:nd, 3:rd and4:th Reference Points (G30P2, P3, P4)

1. Press DIAGN IN/OUT button.
2. Press Menu key under the screen until you can see the option PLC I/F.
3. Press PLC I/F key under the screen.
4. Make settings: DEVICE (1001) DATA ( ) MODE ( M ).
5. Press green INPUT CALC button. You will see no change, but leave it at that.
6. Press TOOL PARAM button.This brings you to the MACHINE PARAMETERS menu which is now open.
7. Press MENU until the ZP-RTN option is visible.
8. Press ZP-RTN key under the screen.
9. Edit P2,P3,P4 settings for X, Y, Z and 4:th axis. The 4:th axis page is not visible unless "4:TH REMOVE" is switched off in the PLC-switch area.
10. Press DIAGN IN/OUT button.
11. Press Menu key under the screen until you can see the option PLC I/F.
12. Press PLC I/F key under the screen.
13. Make settings: DEVICE (1001) DATA ( ) MODE ( U )
14. Press green INPUT CALC button. You will see no change, but leave it at that. This brings you back to normal "USER PARAMETER" status.

As for using the G30 command in programs: My manual says that if there is no Px designation after a G30 command, then the 2:nd Ref Point (P2) is selected anyway.
