The upper limit threshold used for static friction failure prediction is
displayed in increments of 0.1 % in relation to the rated torque as 100
%.
The lower limit threshold used for static friction failure prediction is
displayed in increments of 0.1 % in relation to the rated torque as 100
%.
The creation progress of the thresholds used in static friction failure
prediction is displayed as a percentage. Creation of friction failure
prediction for the upper and lower limit threshold finishes at 100 %.
