Hi Tom,

I have an issue with your controller. I use it to make a palletiser.

My setup:
a) 2x power supplies 80VDC – 18amp for the snapamp only
b) 1x kflop
c) 1x snapamp
d) 1x konnect

I use 4 axes, i.e. X, Y, a rotating clamp, and an elevator.

The problem happens randomly.

The machine stops working in the middle of a movement and to restart it, I must make a hard reset.

I use the function MoveAtVel for each axe.

I try to find the problem to repair it, but I cannot figure where to search.

Is it an overload problem for an axe?
Is it an overload problem for a set of two axes with the value of the current limit?
Is it an overload problem for a set of two axes with the value of the snap supply clamp?
Is it a software problem?
Is it a memory problem due to the calculations of the too many points?
Is it a hardware problem?

I attach you the file used for the details.

Thanks in advance for the help,

One issue I see is:

char strTempo[10];

only reserves space for 10 characters and you are writing more than 10 characters into it. That can cause a crash. Such as:

sprintf(strTempo,"Operation - Rangee %d",numRangee);

The "Validate" option finds bugs like that for you.

You should also add function prototypes so the correct parameters and return values is used.

Thank you Tom,
I will check what you said and make the necessary change.

Hi Tom,
I check and repair all my code with your "Validate code", all done no error.
I check and repair all my code with your "compile code using Ti Compiler" and I have an error:

undefined first referenced

What does that meen?

Please post your include file:

fonctionsCalculs4Mv20200928.h

Voila

__fltlid C:\KMotion435b\C Programs\PAL-Master - 20200928a.obj

That is a bug on our end as we aren't including all the TI Compiler's intrinsic functions. The code compiled without any warnings which was the purpose.

On this DSP "long" variables are the same as "int" variables 32 bit signed. If you replace long with int the TI Compiler should have all the functions it needs. Within printf statements %ld codes should be replaced with %d.

Note the code total size is over 65535 bytes. So be aware the code will overflow into the next Thread Space if used in Threads 1-6. So in that case the next Thread should not be used.

HTH

Thanks, if I use the thread 7, where the overflow go?
This is a problem?

Hi Tom,
I try to remove the stuff that I can and I made functions with other.
My code have a total 64900 bytes.
This is correct? No overflow possible?

Correct. If Total is less than 65536 should not overflow.
