Sets or queries the hysteresis level of the PLS.
If an axis stops at a specified PLS position, the state of the digital output may be continually toggled due to slight oscillations in the actual axis position.
To prevent repeated output triggering, a hysteresis value can be applied around the PLS positions. Typically, 5 to 10 encoder counts (converted to position units) is sufficient.
If the axis driving the PLS stops at a PLS position within the hysterisis range, the PLS state does not change.
PLSHysteresis is only necessary if the system stops on or near a PLS position.
