Help with inverter ATV61HD22N4Z Inverter 22KW 380V
I recently bought a Schneider Altivar 61 ATV61HD22N4Z (22kW, 380V) VFD from eBay. It was listed as new in box.
After a power outage, the drive stopped working completely. The seller sent me two replacement boards (the control board and the display/interface board). After replacing them, the VFD worked perfectly all night without any issues.
However, the next morning I powered the drive off and back on again, and now it no longer works.
At this point, I’m not sure if the problem is:
- the internal power supply,
- the main power section,
- damaged capacitors,
- or something else that could be damaging the boards again.
Has anyone experienced something similar with an Altivar 61? Any ideas on what I should check next?
Thanks.
