Hello all,

At a plant of one of our costumers, we have 3 frequency drives (G120C PN) installed. They each have to control a motor that spins at a given speed. We've installed that, but because the drives are stand-alone (drives are configured via BOP-2), there's no profinet cable to communicate to the drives. Now, logically, they have all the time a 'bus failure'. It annoys the costumer, so I wonder if there's a parameter that lets the drive know that there's no profinet connection. Does anyone know how to do this?

Thanks in advance!! :)

Hi Christoph,

Thanks, I've already found this parameter, but I was not sure.

Do you also know why our costumer sometimes gets error 'F30003'? I know that the error says 'DC-link voltage undervoltage', but we don't know what could cause this error to show up...
