I repair drive V3F16L Kone, professionally, warranty 12 months, lowest market price.
I am engineer electronics, constructor, with 30 years experience.
So, two years ago, I have made entirely schematic for this drive. After researching I know what is problem. Then I have made "Test Unit" for completely testing drive.
My service include defecting and preventing service.
All the inverters I have repaired they are working fine over 1.5 year.
Best choice is to repair them per lowest price.

Best regards.
