When the 230V supply is restored, and a reset command through the V14 object technology is activated, the alarm does not disappears and the drive cannot be enabled. Is this procedure wrong ? Sincerely, Pier Giovanni

Please have a look on chapter 10.2 of the S7-1500 TIA manual. https://support.industry.siemens.com/cs/de/de/view/109749262/en Check if the supply voltage available on the V90 or if additional contactors are open. You can check r0026 if DC-link voltage and therefore line supply is at nominal value.
