The HEZ occurs at 60
°
electrical. If the
transition of V from 0 to 1 at the HEZ point
is in the negative direction (like this
example), then the hall effect sensing would
be considered reversed. If the transition of V
from 0 to 1 at the HEZ is in the positive
direction, then the hall effect sensing would
be considered standard.
Positive refers to the direction of the
electrical cycle.
The description of Ixx91 in the Software Reference manual shows the common values of offsets used, for

Ixx91 mask = $80 + $40 + $0B = $CB
For Turbo PMAC2 axis #1, this would give us
I191 = $CB0000
