Does it mean that pattern is not the right one? No, that is inherent to trapezoidal commutation. > 3) With cfg=qh,qh,qh > setp bldc.2.scale 2048 > setp bldc.2.poles 8 > setp bldc.2.pattern 4 > setp bldc.2.value 0.1 > > There are 2048 CPR encoders.

The scale needs to be the number by which rawcounts increases with one full turn of the spindle. You need to set the number of poles correctly. Also, there is a 50% chance that the bldc.N.scale needs to be a negative number. -- 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.
