I have a proble with keb f5 inverter its capacitors and rectfier bridge was damage i changed it but now it gives an error E.PU. plz suggest me the solution.a thick film 05.f0.0019 alo seems to be damage.

Most likely when the DC bus capacitors and input rectifier were damaged, it also damaged the circuit board.

Wiser to replace inverter or send it in to a KEB facitlity to be repaired.

Keb inverter and lenze inverter

I would have to say that you will not be able to swap the KEB inverters with the Lenze inverters or the Lenze inverters with the KEB inverters.

The PLC ProfiBus system would most likely need to be re-programmed for the change.
