You have to check the complete oscilloscope waveform. This negative value could be due to PMSM acting as a generator.

The display shows the instantaneous voltage, and as the machine is spinning, it will create an AC waveform, so you should get negative and postive values.

please follow the comment from Dr. Narayanaswamy, place a scope to view the signal instead of a display. If you need more information on how to use the tools, here are 3 free trainings.
