Only worked on one of those ECO blue motors. If I remember correctly I think the motor module feeds the DC volts the board then uses to send a signal back to the motor.
But how much money do those ECMs really save especially in Texas where the ACs are usually in full send And like you said when they fail?$$$😭 Besides why can't they use multi speed PSC if a furnace can kick down to low speed for heat I have to believe a capacity based control is possible and probably cheaper

Dude!!! That actually makes perfect sense! There is no inverter on the board!
