Internal program error

What default parameter are you looking for.

There are many parameters in the F5 inverters. Best source of information as to how the unit is programmed is to obtain this from whom you purchased the inverter from.

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.

The CP mode parameters are a small list of parameters that are mapped from the application parameters. Not knowing what you are trying to do with the inverter, it is very difficult to tell you what needs to be programmed.

90% of the machines that us the KEB inverters use the application parameters to gain the full functionality of the inverter.

The machine manufacture whom built the machine that the inverter is installed in should be able to provide you with parameter settings.

There are instruction manuals on the KEB site.

You will want to look at the manuals under: Frequency Inverters > COMBIVERT F5 > Control Circuits > Basic (51)

The manual that came with the inverter has instructions on how to go from mode to mode.

If you do not have the manual, these can be downloaded from the KEB web site.

at the first i want to know the error message appear after switch on the power on the drive with out any load or with load .

you can download the keb f5 manual from this site

By default the F5-C inverter uses an analog signal for speed command.

Review the manual that was provided with the inverter for connection of signals.

If this inverter does not have default settings, you will need to determine how it is programmed.

What F5 inverter are you asking about? There are many different control stages and each has different default parameter settings.
