[Pr. PF40_Machine failure prediction servo parameter (MFPP)]
[Pr. PF40.0_Friction failure prediction - Threshold multiplication]
Set a multiplying factor for calculating the threshold used in the friction failure prediction function.
The smaller the multiplying factor for the friction failure prediction threshold, 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 multiplying factor is 5.
[Pr. PF40.1_Vibration failure prediction - Threshold multiplication]
Set a multiplying factor for calculating the threshold used in the vibration failure prediction function.
The smaller the multiplying factor for the vibration failure prediction threshold, 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 multiplying factor is 5.
[Pr. PF40.2_Friction failure prediction - Dynamic friction selection]
Select the dynamic friction to use 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.
