Imagine that the green one is your left leg and the yellow one is your right leg.
You step your green left leg forward first followed by your yellow right leg, take 50 or so steps forward and then you reverse the sequence by walking backwards.
That is what the iacv does, it has two sets of coils, coil a steps first followed by coil b, this moves the rotor in one direction, if you reverse the sequence; coil b first then coil a it reverses direction.
That's why it is called a " stepper motor "
The reason the iacv is taking so many steps is to make sure it is at the open end stop and then " stalls " or slips at the very end, then it takes as many steps in the closed direction as is determined by the engine temperature to arrive at 1000 rpm.
Both voltages are the same value but i reduced the size on the screen of the green one to make it look clearer to see the reversal in the sequence.
That's great max - thx.
Can you quote the module signal labels or pin IDs (or an image showing "where") you hung your probes off for membership folks who wish to repeat your results for themselves?
Maybe you have elsewhere in the Forum - so maybe just re-paste the URL here. This is useful info for those who may encounter similar run-time behaviour challenges and may wish to compare.
