This leads on from my FobCo thread.
My VFD has finally arrived and I am out of my comfort zone.
We have established that my motor can be wired Star or Delta.
The Motor terminals are labelled ABC and the VFD terminals are labelled UVW.
Google tells me this is just phase sequence so ABC=UVW=L1L2L3.
Question 1
So I wire thus:
A>U
B>V
C>W
Correct?
Question 2
The motor has
A=Red
B=Yellow
C=Blue
But as it is currently wired Star all three of the others are wired to a single terminal. To rewire in Delta I need to connect each of the other three wires to A, B or C.
But they are Brown, Black and White. Google hasn't helped me here.
So which goes where?
I know where the earths go!
Question 3
The motor has 2 purple wires which went to the DoL starter. There is a photograph of the wiring on the FobCo thread if this helps.
What do I do with them?
Question 4
The VFD instructions state use of shielded or screened cable from the VFD to the motor.
The VFD will be mounted on a bracket on the drill so the cables will be barely 30cm long. I won't have any electronic devices nearby.
Is screened cable essential?
The instructions are clear on earthing if I must use it.
Question 5
It seems I now have no use for the DoL starter.
Is it likely to be of any use to anyone and so worth as a freebie in the appropriate section?
