KEB 07 F5 Error code E. Puch what will cause this error and how do i clear it

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

See "Tips and How tos" section.

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.

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........

Look under the E.puch tip section.

E.puci During the initialization the power circuit could not be recognized as invalid.
