It seems not that difficult but really hard to me. i've got a Rockwell PowerFLex 700, 380VAC, 3-Phase Frequency Inverter and a SEW 220VAC-Delta 3-Phase. How can I drive this motor properly? Change Wiring from delta to star is forbidden, so, any help?

 

there is no parameter in the 700 for delta vs. wye. I would hook it up and set the motor data, try an autotune and see how well it works.

if it doesn't work report back to us.
