Need Help!- EIA in fusion 640 wont tool change

[mikey B]

Just got a new to me 99 fh5800 with a fusion control. The problem i have is it wont make a tool change in auto mode. It will with the same line of code in mdi though. The alarm i get is 296 NO TOOLCHANGE (AXIS NOT ATC POS). Checked the parameters with another 5800 of the same year in the shop that does run in auto and they are the same. WTF I have management up my ass to get it going like yesterday. If any one has a suggestion it would be great so the boss can kiss my @#$%&. Did I mention I hate mondays!!!!!!!!!

Probably need to bring it to zero two. Use G30 G91 Y0.0 to bring it to the tool change position then call M06

[mikey B]

The code in the other machine and in this one is N1 G0 M06 T6 and it works fine both are the same year same control and both are 5800's. The same code works in mdi but wont work when in auto.

Here is a tool change from a FH580 for reference

.
N102 G0 G17 G40 G80 G90 G95
(3/4 BALL ENDMILL TOOL26 DIA .750 )
( FAR SIDE ROUGH .025 STK )
N104 G30 G91 Z0. Y0.
N106 T26
N108 M6
N110 T1
N112 S20000 M3
N111 G61.1

Tried that format, Did the same alarm!

Look through your program files and J parameters for M codes (starts at J41) and make sure the previous shop didn't write their own "M6" tool change macro. I've seen this before and you can simply remove the J parameter call for it and then the machine will use the ladder M6 instead....

Other issues that can stop it also...

Bad or missing Tool data for the T number, .... Tool life is over, .... incomplete Tool Data, ...

[mikey B]

Checked the J parameters, all the same as the other machine that works. Got to be something in the parameters though, is only two months different in the build dates.

I just broke the program down with one code per line and I dont get the alarm till it reads the M6. Machine had programs it from previous owner but the @##$ forman dumped them all. Should be his problem now but its not.

[psychomill]

It's possible that the machine ladder was changed but people don't usually do that. Besides, if you can MDI a toolchange from your spindle being anywhere in the machine, then your ladder should be OK. The glitch is on the AUTO mode.

So, did you check out your Tool Data to see if something is missing there?

[mikey B]

Just rechecked tool date to be safe and didnt see any problems or differences from other machine. Had someone else look to be sure.

[psychomill]

so, if you broke down your code to something like this.... would it work in AUTO mode?

G0G91G30X0Y0Z0
G90
T26M6

note: MDI can do things quite differently than in AUTO mode so we need to test in memory mode

That's other test as well.... rearrange your T code to come before the M6 instead....

There is a PLC parameter to set the language needed for a tool change. Look in the elecrical manual at the plc parameters (R's). The one that needs to be changed is the one that says "tool change by plc?" you want this valid. This will make the plc do the move to the tool change position so you won't have to write G91G30X0.Y0.Z0. There is also a parameter there to set if you need to actually use M06 to exicute the tool change. If you do not change these parameters your language needs to be:

G91G30X0.Y0.Z0.
T26T30M06
...


meaning move magazine to tool 26 change tool and then move magizine to tool 30. (the second T code can be T0 if you don't want the magizine to move to the next tool)


Hope this helps sorry I don't have a manual by me to give you the parameter numbers
