In my experience, the only weak link (other than being lower quality to brand names) with these spindles/VFD's is a lack of cable restraint. Both at the Spindle and the VFD you need to restrain the cable so the don't move around. I've only ever had 3 fails with connector faults and all of them where because the cable restraint I'd fitted had been left unconnected after the customer had moved or adjusted spindle etc and not fastened cables back up.

It's common sense really. . . which isn't so common these days.!
From your reply i would say you are unaware of proper wiring and component selection requirements :)
