[Pr. PF41_Failure prediction - Servo motor total travel distance
(FPMT)]
Initial value
0 [10 rev], [m]
Set a servo motor total travel distance required for determining the threshold used in the friction failure prediction function and
the servo motor total travel distance failure prediction function.
When Servo motor total travel distance exceeds 1/2 of "Failure prediction - Servo motor total travel distance", the threshold
will be automatically calculated for the friction failure prediction function.
When [Pr. PF34.2 Servo motor total travel distance failure prediction warning selection] is set to "1" (enabled), if the servo
motor total travel distance + the value of [Pr. PF47 Servo motor total travel distance offset] exceeds the value of this servo
parameter, [AL. 0F7.3 Servo motor total travel distance failure prediction warning] occurs.
[Pr. PF42_Friction failure prediction - Average characteristics
(PAV)]
Initial value
0 [0.1 %]
Set the friction torque average value at the rated speed.
This servo parameter is enabled when [Pr. PF34.0 Friction failure prediction warning selection] is set to "2" (enabled (manual
threshold setting)).
When [Pr. PF34.0 Friction failure prediction warning selection] is set to "1" (enabled (automatic threshold setting)), the value
will be calculated automatically from the estimated friction torque at rated speed.

[Pr. PF43_Friction failure prediction - Standard deviation (PSD)]

Initial value
0 [0.1 %]
Set the friction torque standard deviation at the rated speed.
This servo parameter is enabled when [Pr. PF34.0 Friction failure prediction warning selection] is set to "2" (enabled (manual
threshold setting)).
When [Pr. PF34.0 Friction failure prediction warning selection] is set to "1" (enabled (automatic threshold setting)), the value
will be calculated automatically from the estimated friction torque at rated speed.
[Pr. PF45_Vibration failure prediction - Average characteristics
(VAV)]
Initial value
0 [0.1 %]
Set a vibration level average during servo motor operation.
This servo parameter is enabled when [Pr. PF34.0 Friction failure prediction warning selection] is set to "2" (enabled (manual
threshold setting)).
When [Pr. PF34.0 Friction failure prediction warning selection] is set to "1" (enabled (automatic threshold setting)), the value
will be calculated automatically from the estimated friction torque at rated speed.
