It wants the password because you are changing parameters.

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/

Purportedly pressing enter clears the error message. https://www.manualslib.com/manual/1293218/Keb-Combivert-F5.html?page=55#manual
The error means the "power circuit is not ready" according to the error code page. http://www.servotechnica.spb.ru/viewdocument/KEB_CD/manuals/f5/f5s/00f5subk250.pdf?page=33

The following page has the contact details for the company in the US as the last listing. http://www.servotechnica.spb.ru/viewdocument/KEB_CD/manuals/f5/f5s/00f5subk250.pdf?page=33

Do you have a KEB Combivert? What model is it? Is your error .a prf or E.hybc or both? Hard to tell because you have posted 6 questions apparently.

Go to the KEB site, there are manuals and troubleshooting there, you will need to choose your correct model

From another Fixya answer:
If you are talking about error code 59 then the error is E.HybC.

E.HybC means that the feedback card on the inverter has been changed.

You must confirm the change at parameter ec.0 or ec.10. The inverter reads the value from the feedback card so all you have to do it hit enter to confirm the value.

If you have not changed the feedback card but the error continues to come back then there is a problem with the feedback card or the control card.

These are all messages that follow overheating. E.nOH indicates that the heat sink has returned to the normal temperature range and the unit can be reset. E. OH indicates that the power module is over-temperature. This could be caused by insufficient air flow at the heat sink. That is caused by dust/dirt. The ventilator could be clogged or the ambient temperature is too high. E. OH2 indicates that the motor protection relay was tripped. Check for dust/dirt and clean any filters. Make sure that nothing is blocking the air flow around the unit.

KEB uses these error mesages on the CombiVert F6, https://www.keb.de/fileadmin/media/Manuals/f5/control/f5m/00f5mebk320.pdf .

I hope this helps.

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.

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.

Tips How Tos for Inverter KEB COMBIVERT F5

E.puci During the initialization the power circuit could not be recognized as invalid.
E.puch power unit changed
power unit identification was changed, with a avalid power circuit this error can be reset by writting to SY.3. If the value displayed in SY.3 is written, only the power-cricuit dependent parameters are reinitialized. if any other value is written, then the default set is loaded . On some systems after writing SY.3 a power-On -Reset is necessary........
