Thanks Sasi Hi Sasi, Take a look on the parameter list: MICROMASTER 440 - Siemens It's strange that you have 0V in r026 while you have 400V in the line it is possible, that the power surge havedestroyed the voltage measurement in the DC-Link MM420 Alarm A0503 - Siemens Industry Online Support - Technical ...

Thanks Sasi If DC voltage at DC+ & DC- is 562 (actual measured) & r026 displays 0, its hardware fault. (DC voltage measuring circuit is faulty) So please check & replace the card. HTH.

This does not mean physical damage or failuer visible by naked eyes. Needs to be check/test complete circuit. Please see attached sheet for more information. HTH.
