Hello
I have a HY620 with vfdmod that was running flawless. I recently added a braking resistor and now I have quite often Err4 when braking.
I didn't troubleshoot this yet but this point out another issue : The error is correctly display in my custom panel but this has not impact in LinuxCnc.
If I don't notice the error on a tool change for example and proceed, the spindle won't start and I will crash.
I select "Stop" on the VFD to clear the error.
How can I link this VFD error to for example the E-Stop signal ?

Might have to set the "ramp down" to give more time for the spindle to slow down, done on the VFD.
The error is correctly display in my custom panel but this has not impact in LinuxCnc.
The error signal has to also be wired to one of the control inputs in HAL, like suggested to e-stop or machine enable, or if there is spindle-amp-fault. I am sure the 2.8 and master have amp-fault inputs as i have them in use, but i use no spindle so never checked.
