I use a 7334 motion board with LabVIEW 7.0, NI Motion 6.1.3 and MAX 3.1.0.3021. I tried to change the polarity of phase A signal of the 2nd encoder with the flex motion VI "Configure encoder polarity.flx". Nothing happened. After troubleshooting I recognized that the 2nd encoder is wired to the 3rd one in the 8 axis cluster of the VI(Of course I checked the wiring of my encoders). But in the MAX tree 7330 Default settings/Encoder settings the number of the encoder is right and changing of polarity works. Is this a bug in flex motion software?
