■Threshold reset method
To automatically reset thresholds after the upper and lower limit thresholds are set automatically, set [Pr. PF34.0 Friction
failure prediction warning selection] to "3" (threshold reset), then cycle the power. After cycling the power, the threshold value
is reset, and [Pr. PF34.0 Friction failure prediction warning selection] changes to "1" (threshold value automatic setting). If the
equipment parts are replaced after starting the friction failure prediction function, reset the friction thresholds and servo motor
total travel distance.
