Re: Phase Perfect Simple
¿ªÔÆÌåÓýBruce, I forgot to thank you for sharing the error code. That helped me understand the issue with PP Simple model and braking. I still don¡¯t have enough information to know how Enterprise overcomes this other than the line filter which would help minimize the voltage unbalance during braking.

?Yes Aaron, braking is done by DC injection in Felder machines. At least what I have seen so far. 3 phase AC to DC conversion exists but it costs more.

I think I read somewhere that electronic motor breaking in these machines are done by sending flat-line DC current through the motor windings (as opposed to alternating current).? It would make sense that the brake board uses only single-phase power.? There is likely an AC-to-DC power supply on it which really only works with single phase input.
