Help Re-installing PRT with Yaskawa VFD

[tas99]

I am in the process of reinstalling my older PRT Alpha with a Yaskawa VFD and HSD spindle but I misplaced the wiring diagram for the Yaskawa.

I left the wires connected in the controller so I assume they will be ok. It's the connections inside the VFD that I need help with.

Any help would be greatly appreciated.

Hi Tom
I have the manual for a Yaskawa V1000 and can Email you the standard connection diagram if that will help.

Hi Bill,

I appreciate the help.

I might have been a little quick in this post fro help. After about an hour looking through old posts I think I have the information need to wire this thing correctly. The only thing I need to do is verify that the 220 Single Phase connects to L1 and L2 (as seen on other posts). My concern is that the screw is tight on L2 and loose on L1 and L3. I would have thought that if it came off of L2 that screw would be loose.

I'm just not sure.
