Is there any way to increase the torque/amp output when bldc motors are going thru the alignment sequence? I have to manually assist the screw till it gets reference. I have set the initial value to 1.

bldc.0.initvalue is the thing to change.

It can be anything up to max drive current, so just use a bigger number. It can also be negative.

Thanks it was 0.5 from a config I got somewhere, I thought it was a multiply value -thanks for the clarification!
