Hi Polynex
Normally this problem happen with Mocon PCB and I/O Board, Vector drive and Y/D contactor.
You said you already tried MOCON, I'll suggest you to try to tighten up Y/D connections. I did face this problem many times i.e.
1) In SL-30, It was bad Y/D Contactor connections
2) Other SL-30 machine. It was bad vector drive. There input power was fluctuating, also corrected.
3) VMC, it was bad MOCON PCB
4)SL-10, it was bad I/O Board
Hoping this will works for you.
Thanks
Harvey
