Hi all,
I’m working on a KEB F4-C 25 kVA inverter using Kombivis5 software. I’m trying to change various parameters, but the UD0 and UD1 parameters seem to be password-protected. I’ve tried the passwords 100, 200, 330, 440, and 500 as mentioned in the manual, but the inverter status remains "CP-RO", and I still can’t change the parameters.

Is there any method to reset the inverter to factory default settings, or another way to unlock the parameters? Any advice would be really appreciated!
Thanks!
