The quirk of the weekend(long post)
Thanks for the help guys,
So this weekend I tried running the drive again, I took out the trusty analog vom(do not have a digital yet) Check the voltage on the 3 legs from the rotary. 220, 220, 190! Next I check the voltage from the step down transformers, (220 to 110) 190 in 100 out. (2nd 220 to 120) 220 in 120 out. (3 phase 220 to 70) 220, 220, 190! out 70,70,60. Ah HA! Looks like we found something. So, I check and 1 220-110 transformer is wired to 1l1,+1l2, and the 2nd is wired to 2l1, +3l1. Rewire so both go to 220 line. Now have correct voltage coming from both transformers Yay! Try starting spindle, Drive fault (4000 error) Damn! Re-set control, home axis, try starting spindle, Yay! It starts no fault:banana: Make 1st chips. Stop spindle, try to re-start. Sometimes it does sometimes it faults? I measured the voltage when I start the spindle and the voltage from the 3 phase transformer output jumps to ~85v at the spindle start. I think this is faulting the drives.
Can anyone give me a suggestion? Do I need to balance the voltage from the rotary better? If so how?
Sorry about all the questions but I hope if I get this sorted out maybe it will help someone in the future.
Thanks,
