The reason is that the incoming power is converted to DC first so a change of Fase sequence is not relevant anymore. Regards, Marcjan

PISCEAN 2010 Posts: 8092 Rating: (884)	What you want to do? Do you want to rotate motor in reverse directionwhen it is rotating in fwd direction? Or do you want to run motor in following manner.? RUN FWD - STOP- RUN REV. I presume you want to rotate motor in FWD-STOP-REV manner. Configuer digital inputs & hardwire as per logic, it is possible.
