Hello Tom,

Another simple lovely topic which I couldn't solve by myself :/

I have external buttons connected and physically working (checked in Kmotion IO) and I try to make them operate the machine, I followed the instructions here (archive/attachments/Adding%20External%20Buttons.pdf) as much as I could but without success.

Compiler does not give any error but when clicking init the DRO gets yellow and stay yellow.

Please help !

Cordially

Francois

Hi Francois,

You should be able to debug things like this yourself. My guess would be ESTOP is being triggered. Add printfs to determine what is happening.

Morning Tom,

Crap you were right for both...



Modified the code, now works properly, thank you Tom !

Hello Tom.
I am trying to add an E-stop (emergency) button, as indicated in this document.

Do I assign it to the M code (Stop) as shown in the figure below. Is that correct?

Another question, when I press the Estop button, it executes the C code and disables the axes, if for some reason the communication between the PC and Kflop were to be lost, this method would not work.
Is there a way to make the E-stop button work in Hardware?
Thank you very much, regards.

Hi Ibzan,

Do I assign it to the M code (Stop) as shown in the figure below. Is that correct?

No. Add it at he end of your Init C Program.

Is there a way to make the E-stop button work in Hardware?

Yes. Add C Code to do whatever you want EStop to do. ie disable axes or turn off contactor relay.

Yes within the 'if' condition.
