I have a question regarding a system set up here to control a brushless servo motor using the National Instruments PXI-7358 motion control card along with the UMI-7774 interface board and a sinusoidal commutation amplifier. When initializing the axis (within MAX) using the "Onboard Commutation" option, I get error 70069 indicating an invalid hall sensor state error. I checked to see that all the sensors were working correctly (active high), and even tried rewiring the system to change the polarity of the output (active low), but got the same result when initializing the axis.
I've already had a similar system working using all the same components and a brushed DC motor, so I know all the hardware is working correctly. Can anyone provide any insight? Thanks.
