Thanks guys finally got it fixed you guys were a lot of help, fhe guys had just installed that VFD brand new powerflex 700 and the F.L.A was set too low as well as parameter 42 was wrong for the load it was running. But it is back up and running !
Thank you guys, and the load is a 20HP 3 phase motor connected to a VFD PLC system. The issue i am having is that the VFD is faulting out at the set threshold of 815VAC. However when the load is on (Motor) the VFD runs at a constant 640VAC which is wrong because when i measure the actual output...
Line 1 to ground is 500vac, Line 2 to ground is 480vac and Line 3 to ground is 30vac. Why or how does this happen, my supervisor mentioned something about "floating ground in the facility"
