I am trying to wire up some reclaimed 1305 VFDs. It is entirely possible these are junk, I don't know much about their history.
I am attempting to wire this up on a M head Bridgeport. I am running the motor wires to the existing reversing switch. I have added a 10k remote pot for speed control.
I have 240 VAC 3 ph coming into the control on L1-3. I have the drum switch wired to T1-3. The remote pot is wired to TB2 1-3. There was a jumper on 7,8 that I left in place.
I have not wired anything else.
When I power it up, the HMI flashes the version # and "Connecting" alternatively. It does this for as long as I have been willing to wait so far (up to several minutes).
Q: Do I need to jumper 11,12 (Enable) for it to do anything with the HMI? Q: Can I jumper 6,7 (Start) and it would energize the output whenever power is applied to the drive?
Q: The book mentions SW3 selects the freq source. I think if I leave this open that the remote pot is enabled. Can anyone confirm this for me?
I have two of these drives. I have swapped the HMIs into the one drive I have wired so far, with the same effect. I could swap the drive next, but wanted to see if there was something obvious first. Rewiring isn't that difficult, but why go to the work if not necessary.
Thanks
