Keb inverter and lenze inverter

I would guess that this is off of a Rieter machine (C51 Carding Machine). They would be your best source of information.

Verify that the unit is properly programmed and that the control wires are correct.

Best option would be to contact manufacture of the machine that the KEB Combivert is installed in for assistance. This way you will be sure to operate the system within the design specifications of the machine.

Easiest way to program the KEB inverters is with the COMBIVIS 5 software. This can be downloaded from the KEB web site. http://www.keb.de/en/service-downloads/downloads.html?tx_damdlbycat_pi1%5Bcat%5D%5B2021%5D=2021&tx_damdlbycat_pi1%5Bshowgroup%5D=4418&tx_damdlbycat_pi1%5Bdocutype%5D%5B6%5D=6&type=767

There are over 1500 parameters in the inverter. These have been setup by the manufacture of the machine so that the machine functions the way it was intended to in a safe trouble free manner.

Before one defaults the inverter you should always use the COMBIVIS software to obtain a complete upload of all the parameter values. This way you can always get back to the settings before the inverter was set to default.

Also with the COMBIVIS software you can access all the parameters in the inverter. With the software the Fr parameters are where you would find how to reset the inverter to default values.

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.

Verify that the cooling fans are operational and that the heatsink is actually hot to the touch.

If the heatsink is not hot to the touch there is perhaps a problem with the temp. sensors in the inverter.

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.

Please provide part# of the unit in question and manufacture of machine.

All spare parts for your machine requests should be routed to the manufacture of the machine.

Thypically there are no field servicable parts in the inverter.
