the other 'scope channel is for the hall effect output for the U pulse.
Rotate the motor either by hand or by some low speed means and a generated sine wave should be observed on the U phase out. The square hall effect pulse should be then aligned with the the centre of the sinewave output.
The other Hall pulses can be verified the same way with the corresponding motor phase.

Hi, is it possible to buy third party encoders with hall sensors or simulated hall sensors, I have never seen them advertised. The reason I ask is because I have a motley collection of AC servo motors with no matched drives and it occurred to me that putting such an encoder on these it should be possible to drive them with generic brushless DC servo's of which I have in abundance, just a thought.
