Hello everyone,
I currently have one emergency button connected to the EStop pin of my MK3/9 Board. This button is working as I'm expecting it to do.
As I got a new vfd that can switch a relay in case it goes into a fault state I would like to incorporate this into the estop routine. It should cause the software to go into estop if the vfd reports a error on this relay.
My first impulse was to just connect the relay to one free input on the input board an configure it as a estop pin, however I quickly noticed that there is no way to configure a normal input as a estop.
Next I tried using one of the limit inputs where I set the estop flag, for whatever reason this does not work either for me. Somehow the estop flag for the limit inputs does not work on my configuration (hard and softlimits are enabled).
I finally settled on connecting it to a input and configured this input as a shortcut for estop. This works ok most of the time, but it does not work while jogging the machine manually (However its unlikely that the vfd will report an error during manuall jogging).
Of course i could wire it up in series with the emergency button, but I would like to have it separately.
How are you handling this?
Best Regards,
Klaus
