Hello there,
Like many it seems, I am new to the world of VFD's and finding little support.
I got a 2.2kw 220v spindle from Amazon. I wired it as directed and programmed it according to what the dealer sent me. This was before I found posts here. In their settings it was set for 4 pins. I got it all set and hit run. The spindle stared to spin up but as it approached the upper speeds it would almost disengage the spindle part but the motor would still run, then I would get an EOCA error. I changed several settings and tried again but nothing helped.
THEN, I found more posts and reset everything to how they suggested... The spindle would spin at low speeds but as soon as I increased it, the error occurred again.
In checking my wiring, I found a pretty significant issue. Although I assigned the correct wires from the VFD to the pins on the motor connector... I erroneously though that the connector would only fit in one position... such was not the case. So all that time, I had rotated the connector 1 pin clockwise. So the hot leads were actually on pins 1,3. and 4 (4 being the ground).
When I plugged it in correctly, now the second I hit the Run button, it shuts off and I get the EOCA error.
So, my question is... is it likely that I damaged the spindle with my first setup and that is why it won't work? Also, does that fit for what would have happened with a hot lead connected to a ground?
Thanks so much for any insight!
Oh... one more question... if these are 3 phase motors, why is it set for only 2 pins?
Thanks again,
Chris
