ATC Issue (resolved)

[repauli1]

I am having a repetitive issue with the ATC, I have initialized it, I have F2 Reset it. I have tool1 in spindle, request tool3, spindle goes to home, then G30 tool change height, carousel slides in over tool holder, spindle un-clamps, with air blow, Z goes up to home and it stops, reports Mem14 M101
The spindle remains un-clamped and air continues to blow. Attached are photos and report

Looks like the control is not seeing the signals it wants to see during the tool change process.
New build?

[repauli1]

New retrofit yes, if it is waiting for tool unclamp, why would it raise z axis to home? ALT-I manual tests indicate both those inputs functioning.

The messages that Marty highlighted would correspond to lines 52 ("M101/50032") and 64 ("M101/50022") in the M6 macro.

Since the process continued without error to "311 Waiting for memory #14", corresponding to line 73 ("M101/70014"), we can assume that the carousel came in and the tool unclamped without issues.

MEM14 is named "AtRequestedToolLocation_M", and is evidently set by RotateCarouselStage to indicate when the carousel has been rotated to the new tool. If the carousel has not actually rotated to the newly requested tool (perhaps has not actually started rotating at all) then perhaps the PLC somehow did not get the go-ahead to rotate (evidently the "M94/40" command); or refused to act on it due to some other condition.

Unfortunately, the logic in RotateCarouselStage is beyond my ability to decipher without a more serious investment of time. With luck someone from Centroid who was involved in writing it can chime in with some troubleshooting suggestions.

To echo Marty's final question above: has this control on this machine running this PLC program and M6 macro ever changed tools correctly, or was this the result when you tried it for the very first time?

[repauli1]

No, this is my attempt to get it working properly.
FYI the input spindle oriented is overriden to true, I do not have or need and encoder on vfd because of type of tool holder. I have attempted this tool change at least 20 plus times, always stops here. I cannot figure out what's causing it. Interesting to note there in a N100 in the mfunct6.mac file right in middle of macro, would this not cause macro to stop executing?

What kind of tool changer, machine and how does your tool change sequence happen.
Important to know the big picture here.

You can hire Marc or Centroid Support to get you to the finish line, but need to know what you are working with.
There is a sequence of events that need to happen and be satisfied during the standard Centroid Umbrella Tool change cycle. It seems as though you need a modification to the PLC to suit your machine. We can not assume what you have or are working with.

yep, need more info. photos and description of the ATC type, type of sensors, how the ATC intended logic works etc..then you can tweak the PLC program to match. Not all ATC's are the same.

Did you watch the video link?

[martyscncgarage]

Here is the link he is referring to he has a short video clip in it:

You still need to provide information as to sensors.
Do you have a carousel in and out sensor?
Do you have a tool counting sensor?
What rotates the carousel? (How is it connected to the control?) (Can you manually rotate the carousel by forcing the output on?)

Are you comfortable making modifications to the PLC and recompiling it?

[repauli1]

Yes, I have all those inputs, the Carousel motor is electric with cw/ccw and I have spun it both directions, it operates as expected. I performed functionality checks on all I/O. My background is 30 years owning an automation business, well versed in plc and coding.
