KEB Inverter f5 Error a.prf - 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/

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.

General power stage failure.

Most likely will need to replace the power stage or inverter.

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

If there is no error, the inverter is doing what it is be commanded to do.

Check your control signals to verify that they are providing the proper signals to the inverter.

KEB sells inverters to many different type of lift manufactures. The lift manufactures themselves have good tech support for their equipment.

Tips How Tos for Inverter KEB COMBIVERT F5

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.

Check tips section of Fixya.

i have a prblem in the F5 keb combivert it's show Error
