Noise from ACS800-U11 drive
I have a problem with ACS800-U11-0120-5+E200 Drive.
It have FF51 fault. Also have noise from Power Factor capacitor MKK690-D-12.5-11 after contactor actuated. Did replace line side board, power supply board, capacitor, IGBT's, DC capacitors and still have same problem. Contactor actuating little bit later than usually, DC voltage 690. What could be a problem?

Fault FF51 appear when you have some problem with line side converter (when panel connect to motor side converter board). What kind of fault you have in line side converter? What software was loading into line side board? When you replaced board you set correct type of converter?
About noise. If you about strange crackle noise and it appear when you only turn on a power and the drive is stop then you have bad capacitor. It will be good if you could make measurement of it capacitance, and excellent if you make ESR measurement of that DC capacitor.
P.S. "... еще раз пробуем", улыбнуло.
