I am using MODBUS and have set the watchdog, P2014, to trip after 2000mS. When the control packets stop an error F72 is raised and the motor stops. You then have to press OK to acknowledge the error even when the MODBUS controller is working again

What I'd like to happen is that on watchdog timeout the inverter stop, but return to operating normally without having to press OK when new packets are received. Reason being the inverter is in a cabinet.

Any ideas?

Hello,

about F072.

All you can do it's parameterization as NONE, or turn it into a warning, I think.

Cheers

I guess you could try to do it like this:

But you'll have to figure the correct bits to make it work for V20.
