I have a keb inverter F5, that displays LS, i have the correct power going in but nothing coming out?????

If you are experiencing a "Display Power Not found" error on your KEB F5 Inverter and the DC bus voltage is coming and the control card is functioning properly, there may be an issue with the display or the power supply. Here are a few steps you can try to troubleshoot the issue:

1. Check the power supply for any visible signs of damage or malfunction.
2. Check the display for any visible signs of damage or malfunction, such as cracks or loose connections.
3. Check the wiring and connections to ensure that they are secure and properly connected.
4. Check the F5 Inverter's fuse and circuit breaker to ensure that they are functioning properly.
5. Try resetting the F5 Inverter by unplugging it and waiting a few minutes before plugging it back in.

If these steps do not resolve the issue, it's best to contact a professional repair service or the manufacturer for further assistance. They will be able to diagnose the problem and recommend the appropriate repairs. It's also a good idea to stop using the F5 Inverter until the issue has been resolved, as continuing to use it may cause further damage.

if the display says LS, it means you are missing the speed and direction command. Via the keypad, provide the direction and then the speed.

If using bus communications (Can, ProFi, Mod, ext), there may be a communications command (Software signal) that is not being provided. Hardware and software enable signal required to obtain LS.

Possible that the terminal on the control card is bad due to miss connection or signals outside of the rated value.

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.

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.

you can download the keb f5 manual from this site

LS means Low Speed. The inverter is enabled and is waiting for a command.

Check your speed and direction signals at the inverter to verify if they are active.

Push the function button on the display and see if it changes to something different.

If it stays at 00000 then there is a problem with the inverter.
