VFD Has defantly blown up now!

[Clive S]

I genuinely interested and a little confused... how was the original connector made-off last time, if not soldered?

Okay, the connector pictured is a little different to the usual chinese jobs that have solder bucket terminals.

Where I'm coming from is that soldering isn't regarded as a particularly vibration-tolerant electrical termination method (crimping is widely regarded as superior). Unless the OP had, perhaps, screw-terminals?

Doddy If you are looking at the green connector then I think that is just a 3D printed cover to cover the hole up in the top of the spindle. The original plug and socket have been discarded and the cy cable soldered directly on to the spindle wires.

My personal opinion is that I would not do this but keep the original plug and socket BUT securely fix the cable to the spindle plate so as there can be no movement in the plug and socket as this is a source of problems with vfd's letting magic smoke out.
