The threshold used for friction failure prediction is displayed in increments of 0.1 % in relation to the rated torque
as 100 %.
The threshold used for vibration failure prediction is displayed in increments of 0.1 % in relation to the rated
torque as 100 %.
The threshold creation progress used for failure prediction is displayed as a percentage. Creation of the
threshold for failure prediction finishes at 100 %.
The machine total travel distance is displayed in increments of 10 rev.
The estimated tension value used by the belt tension deterioration prediction function is expressed in 0.1 N units
