I recently got a Teco Westinghouse VFD for my surface grinder and wired it last weekend. Everything worked great for about 3 days, then I try to start the machine and the motor clicks but won't start. I didn't have time to look very closely then so I unplugged it and left it alone. I tried to start it a couple days later and I got an error from the VFD "OC-A" which means Overcurrent trip. I don't have any ideas to try to resolve this. Is there something wrong with the VFD or my wiring?
The motor is a 220v 3/4hp 3 phase 3450rpm and the vfd is a 1hp 110v input, 3 phase 220v output.
Thanks
