Not directly. The webpage refers to a motor standard called X13,
which I believe is different from ECM 3.0 though it may be functionally
the same, or at least similar.
The article did surprise me by saying to swap two of the
three-phase motor leads to change direction of rotation. I
thought surely that would be handled by software.
It would be useful to just find a connection scheme that let me
run the motor and vary the speed. If speed control works the
motor is at least good enough to be useful. Actually "talking"
to the motor via Rx and Tx would be instructive, however.
https://unitedhvacmotors.com/change-motor-speed/
makes reference to changing ECM speed, but only
by setting DIP switches on the furnace control
board. That's exactly what I don't have available.
Thanks for writing, I did learn a little more!
