No, it works open-loop and runs through a sequence of (still sinusoidal) phase angle positions that is hopefully guaranteed to pick-up and centre the rotor. > If so, would it be possible to combine the orientation with homing, since > homing is a time when the user expects the machine to move anyway. Possibly, but there would need to be a homing passthrough built in to EMC2, so that the "homing request" pin would go high, triggering an orient, and then the "aligned" pin in the comp would go high to finish the process. A large disadvantage of this would be that you couldn't jog until homed. -- atp ------------------------------------------------------------------------------ The Palm PDK Hot Apps Program offers developers who use the Plug-In Development Kit to bring their C/C++ apps to Palm for a share of $1 Million in cash or HP Products.
