[Pr. Pf53_Failure Prediction - Servo Motor Total Travel Distance (Fpmt)]; [Pr. Pf54_Friction Failure Prediction - Average Characteristics (Pav)]; [Pr. Pf55_Friction Failure Prediction - Standard Deviation (Psd)] - Mitsubishi Electric MELSERVO-J5 Series User Manual

[Pr. PF53_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. PF51.2 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. PF58 Servo motor total travel distance offset] exceeds the setting value of this
servo parameter, [AL. 0F7.3 Servo motor total travel distance failure prediction warning] occurs.
[Pr. PF54_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. PF51 Friction failure prediction warning selection] is set to "2" (enabled (manual
threshold setting)).
When [Pr. PF51 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. PF55_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. PF51 Friction failure prediction warning selection] is set to "2" (enabled (manual
threshold setting)).
When [Pr. PF51 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.
