[Pr. Pf40_Machine Failure Prediction Servo Parameter (Mfpp)] - Mitsubishi Electric MELSERVO-J5 MR-J5-G Series User Manual

[Pr. PF34.6_Friction estimate area judgment speed setting]
Initial value
0h
Select the setting method of "Machine diagnosis function - Friction judgment speed".
0: Manual setting
1: Automatic setting
Setting "1" (Automatic setting) calculates [Pr. PF31 Machine diagnosis function - Friction judgment speed] in accordance with
the servo motor operation pattern. After the calculation, the new value will be set in [Pr. PF31 Machine diagnosis function -
Friction judgment speed] and the setting of this servo parameter will change to "0" (Manual setting).
When "1" (Automatic setting) is set, friction estimation stops.

[Pr. PF40_Machine failure prediction servo parameter (MFPP)]

Initial value
00000000h
[Pr. PF40.0_Friction failure prediction - Threshold multiplication]
Initial value
0h
Set a multiplication for calculating the threshold used in the friction failure prediction function.
The smaller the value of the friction failure prediction threshold multiplication value, the smaller the threshold used for friction
failure prediction, which makes it easier to predict failure earlier, but also increases the possibility of erroneous detection.
When "0" is set, the threshold multiplication is 5.
[Pr. PF40.1_Vibration failure prediction - Threshold multiplication]
Initial value
0h
Set a multiplication for calculating the threshold used in the vibration failure prediction function.
The smaller the value of the vibration failure prediction threshold multiplication value, the smaller the threshold used for
vibration failure prediction, which makes it easier to predict failure earlier, but also increases the possibility of erroneous
detection.
When "0" is set, the threshold multiplication is 5.
[Pr. PF40.2_Friction failure prediction - Dynamic friction selection]
Initial value
0h
Select a dynamic friction used for friction failure prediction.
0: Automatic setting
1: Dynamic friction at forward rotation torque (at rated speed)
2: Dynamic friction at reverse rotation torque (at rated speed)
3: Absolute value average at forward rotation/reverse rotation torque
When set to "0", the value changes to any of "1" to "3", depending on the operation pattern.
