Leadwell Fanuc 0-MF lost atc macro

Its Leadwell MCV-600XL with Fanuc O-MF , customized by Fong Lee Singapore . So no help from Leadwell directly.

I have backup of parameters but no diagnostic parameters or macro programs, but diagnostic params were in the book so I entered them from there.
So parameter 230 = 6 was from backup , it means M6 calls O9020 , but in the book of parameters there are no parameters between 219 and 250 also there is no mention of parameter 40, in my backup it was 00010001

Also 9894 00000001 , 9895 00000001 in backup but in original book only 9895 is 1

ATC is carousel umbrella type

So my question is how should this macro look, I have tried couple of examples found using T#4120 or T#20 with or without M6 . Using none of these in 9020 what I have got is that in some cases only carousel spins indefinitely in place, or in other case carousel aproaches the spindle, tool is released , carousel lowered and then it starts to spin indefinitely .

Maybe it does not need a complicated macro because it seems all is done i ladder , I have complete ladder diagrams.

This is my Macro page with variables dont know if this is Macro A or B

Hello danilom,
As far as a Tool Change Macro is concerned, parameter bit 0040.5 is important. When set to "1", program O9000 is called by a "T" Code.

If your Macro Variables start at #100, that is, you can't find a page displaying Macro Variables 1 to 33, then you control is equipped with Macro A only.

Macro Programs for Tool Change can be as simple as just positioning the axes in a safe position for the Tool Change, or more complex, interacting with PMC to complete the Tool Change. Its up to the MTB as to whether the PMC carries out the whole Tool Change, or in combination with a Tool Change Macro program. It is impossible to say whether a Tool Change Macro is required or not, without documentation outlining the Tool Change process, or careful examination of the PLC program. If you don't have further documentation for the machine, I suggest that you contact the MTB.

Regards,

Bill

Thanks Bill

I have a complete ladder diagram , tool change is in this order

M19 - orient spindle
M21 - Magazine right
M26 - Tool unclamp
M24 - Magazine down
rotate to right tool
M23 - magazine up
M25 - Tool clamp
M22 - Magazine left

M11 & M12 are to rotate Magazine one position CW or CCW

These functions are listed in manual for ATC troubleshooting

Here are the pictures of PLC ladder

Some progress today.

I enabled Macro B trough 900 parameters , and wrote this simple macro for O9020 from looking at lots of examples around here

O9020;
G40 G80 G98 G17 G91;
G28 Z0;
T#4120 M6;
M99
%

Now toolchange in MDI works but in Auto something strange is happening , after the program finishes there is no alarm and I cant jog any of the axis or issue any movement command even on MDI. Next Cycle starts but halts on any movement like G1.
After power cycling the control all is back and I can run the program once more. It seems that it has no connection with tool change because it will happily do couple of tool changes throughout the program and not hang.

Forgot to inform anyone reading this that the problem was low oil, no alarm on that one but it would only run the program once.
