Drive offset is only relevant for a small proportion of drives, and then only when homing. You definitely need to set the pattern. Unfortunately it isn't easy to know what pattern to use. I normally suggest setting bldc.N.value to a small number (not yet connected to the PID) with a pure "h" cfg (so that it remains trapezoidal) and then keep typing "setp bldc.N.pattern 0, bldc.N.pattern 1 etc until the motor runs properly. Note that there will probably be two patterns that nearly work (the motor might turn, but not at steady torque) and one or two that work properly (if two, they will be in different directions) if you have the right pattern you should be able to make the motor turn very slowly with very low currents. -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
