How to reset F5 KEB inverter step by step. - Inverter Electronics - Others

I may miss the point here. If the question is how to clear the error, page 57, item 4.7 Error Messages, of the KEB instruction manual may be of use. https://www.manualslib.com/manual/1293218/Keb-Combivert-F5.html?page=55#manual

Here is information about the error code:

KEB Error "E. OP"
ERROR overpotential (voltage)
1 Voltage in the DC-link cicuit is too high.
Occurs if the DC-link circuit voltage exceeds the permisible value.
Causes:
- poor controller adjustment (overshooting)
- input voltage too high
- interference voltages at the input
- deceleration ramp to short
- braking resistor defective or too small

Given the very technical nature of the KEB, I lean toward referring to the manufacturer's support. There are quite a number of KEB YouTube videos and a number of supporting documentations available on the web. Perhaps the following will be of use if not an entire misdirection: https://www.kebamerica.com/elevator-support/

Fcon = forward constant

The inverter is operating at the set speed in the forward direction.

Forward CONtinues

System is at the commanded speed in the forward direction.

The KEB inverter does not have a "COM" error.

Where is this error being displayed?

Check your inverter baud rate, inverter address, communications cables and device that is being used to communicate.

If you are connected to the inverter with COMBIVIS, go to parameter FR.01 and enter a value of -4. This will set all parameters back to factory default.

You may be having an issue with the inverters software verison. As long as the inverters are the same part number, you should be able to download the parameters without any issue. There may be some unknown parameters but you should be able to hit ignore and keep on downloading.

Via Combivis, write a value of -4 to Fr.01. This will set all parameters back to the factory default values.

Then download your backup parameter file.

you can download the keb f5 manual from this site

Most likely a problem with the power stage. Unit should be repaired.

Do you have the part# of the unit in question?

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.
