Lenze Inverter Drive E82EV152S4B shorted 3phase bridge rectifier.

TECHNICAL QUESTION I have "repaired" a heidenhain uvr150d power supply(75kw) and a need to do a technical question. The thing is I've found 4 igbt shorted and 2 400v caps broken, Ive replaced everything and checked for another broken components, I didnt find anything else malfunctioning. Its the firs time I "fix" this size of power supply. Ive connected it to the wall in the laboratory (3x 380V) and it worked fine the 5V and 24V. Then ive "shorted" the pins that enable the 650V DC bus and it generated it. The power fail led that was bright initially turned off and the READY UV led bright green. It was everithing fine. It worked well. But the problem is that I didnt use any filter or transformer or trhee fase capacitor (as the manufacturer recommends), so various home appliances (as 2 TVs 2 air conditioner boards and some cellphone power supply) exploted . Ive opened some of this boards and ive found 400v capacitors exploted, so there was a huge peak of voltage above 400V in the 220VAC line( maybe 800V peak). The answer is, are those harmonics natural to this size of power supply? The power supply is working fine and the harmonics its generating are normal? If I test it in the client machine with the appropriate filters transformers and capacitors would be ok? Or it may occur the same as here in the laboratory? Its the first time ive repaired this size so i dont know if it is OBLIGATORY the use of this filters.

Thank you for another great and educational video! I have a Lenze E82EV152_2c that has no output on pin9 +5V and pin20 +20V of the Standard I/O PT. Everything else works fine, also the keypad/display, and applying an external voltage on pin 28 CINH starts up the motor. Any ideas?

Where do you get schematics for some of these drives?

[@PeepawMcDonald]

I draw them out myself. HaHa... After 40years of figuring things out, it ain't too hard. Thank you very much for stopping by. I hope all is well with you and your family.

[@mattdennison201]

You must have drawn out alot of schematics over the years. Do you file them for future use? Would be a cabinet or ten full I assume. 😁
