Hi guys, and thanks for all the responses!
Well, we tested another cable and the problem seems to be the same so I got
a yaskawa GA500 vfd which goes up to 590 hz so it's fine for me since I
rarely went above 500 hz with the other VFD.
Is there any consideration about how to set up this VFD? Beca
By the way, the red ones are the ones I modified to suit what I think the
motor should be. Please correct me if I'm wrong.

You can get a cable tracer and ring it as well. Lock out the VFD and you
don't even have to disconnect anything if you can reach in and get clips on
the UVW wires. A break in the insulation will show up as a bright spot and
a break in the conductors will be marked by a sharp drop off.
If that is
A break in one of the wires would cause it be on two phases, vibrate and
not run. Definitely intermittent as it flexes. A piece of cable is so cheap
compared to another VFD. Just strap another cable onto the cable chain and
run it for a few hours.
If it doesn't fail, it's not conclusive, but if it

By the way. Could a not so good earth grounding of the machine cause this
failure? Although the machine is grounded as always and the VFD was working
perfectly for more than 6 months.

Hi Gregg,
Insulating the whole place and getting it to cool would be indeed cool lol.
But the problem is we already had hot days and this didn't happen.
Yesterday was one of the worst days but it looks like something else.

You could try a micro compressor refrigeration system to cool the air that the
spindle cooling fan takes in.
Here's a unit for $149.78 USD. Have to supply your own evaporator coil.

Sorry I didn't specify the voltage well. It's three phase 380 volts. The
VFD is fed directly with the 380 volts and no neutral.
