How to change Motor perceived direction on Sevcon
Hopefully someone can chime in.
I Converted from a Kelly to a Sevcon (ME0913 Motor) and was having all sorts of issues but have finally figured out that my unexplainable runaway acceleration and over current fault issues are caused by my encoder direction and motor direction are inverted. That is, every time I tried to accelerate to 100rpm the 3 hall sensors would report the motor was moving at -100rpm and then continue to accelerate to -5000rpm in order to try and reach 100rpm. Obviously it would never get there.
I figured I need to swap M1 and M2 on the motor to reverse the motor direction but that only caused the motor to shake as it must now be misaligned with the encoder. So.
Anyone think that if I switch hall B and Hall C I will reverse the reported RPM direction and not change the Motor direction?
Is there a bit in Sevcon I can flip with DVT that can just invert the direction reported?
Any help would be huge.
