With the motor in 0 mode and frequency 0 with low current you should be able to turn the motor by hand and feel the poles.

It could still be the wrong Hall pattern then. You say that 4 of them worked? It uses which transition it is to infer the angle, if the transition sequence isn't quite right, then it won't work. You could try qhi, it is probable that the encoder index is at motor zero. -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable. Why? It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense.
