Checking The thyristors and the IGBT’s in Drives – Entries – Forum – Industry Support – Siemens

Hai All It’s Ok with softwares and other accessories but what I want is say if a layman wants to check wheather the thyristors are ok or not then is there any thumb rule for the same Regards Shamsher. If you missing the internal 24Vdc supply, you can still read it by using the Profibus module with a 24vdc connected on it. ModelSim – How to force a struct type written in SystemVerilog? Possible to decode this into plain english, so an average Mulfimeter could say AF modulator in Transmitter what is the A?

Post as a guest Name. If you see any short circuit at the any multimeterr pin IGBT is mort. I dont want to power up the drive and I want to check the thyristors for healthyness.

Follow us on Twitter Youtube. Emetor Collektor must be open circuit at the two direction If you see reverse diod this is not problem. You basically remove the CUVC board and plug in an extender board that is connected via a ribbon cable to a breakout box that provides voltage test points and more. One way is to check the impedance in between the U1,V1, W1 and the DC bus by a ohmmeter in diode mode.
