As soon as I press run the VFD trips and E004 flashes up, I had a look at page 75 however it doesn't really mean much to me not being an electrician, the wiring all looks fine including the connections, I've tested the spindle with an ohm meter on its own and also with the cables attached for a short to ground as well as an open or short on the U,V & W all of which appears to be ok, I've increased the acceleration time to 15 and 20s still the same error
