I've checked that the terminals are connected well but I didn't check for

I thought about it but I really didn't think such an intermittent failure
could be caused by the cable alone. Do you recommend to install a new cable
just in case?
That depends on how old that cable is, and how much flexing it has
endured in its time. And in some instances, what color the plastic used
for insulation is. Magenta, aka hot red or hot pink, contains a chemical
I can't name but it destroys the copper in the wire by converting it to
a fine, rust colored powder that may, or may not, properly conduct
electricity. That color is most often found in two-way radio microphone
cords as the connection to the tx button, or today, more commonly as the
outer jacket of a sata drive cable in your computers. In either case,
the failure rate by the time its 5 years old, is well up the far end of
the well known bathtub curve. I long ago changed all of mine out for any
color but hot red/aka magenta. End of drive errors.
I have serious doubts that is the problem in this case, since the
currents involved are definitely capable of starting a noticeable fire.
But a hand, run along the length of the cable, looking for hot spots
when the failure is in evidence might not be a bad idea. Or better yet,
tracing the wire with an IR thermometer or infra-red camera.

Have you checked your cabling between the motor and VFD?
And please folks, take a break on the mail server, and trim your posts
