time constant of the RC circuit used. Please note that only the falling edge of the pulse
is precise and should be used for synchronization purposes.
NOTE
The parameters PositionStep, MinimumPosition, and MaximumPosition (specified
with the function PositionerPositionCompareSet) are rounded to the nearest
detectable trigger position. When using the Position Compare function with
AquadB encoders, the trigger resolution is equal to the EncoderResolution of the
positioner specified in the stages.ini. When using the Position Compare function
with AnalogInterpolated encoders, the trigger resolution is equal to the
EncoderScalePitch defined in the stages.ini divided by the interpolation factor
defined by the function PositionerHardInterpolatorFactorSet.

MinimumPosition, MaximumPosition, and PositionStep should be multiples of the
Trigger resolution. If not, rounding to the nearest multiple value is made.
