[Pr. PF40.4_Static friction failure prediction - Threshold multiplication]
Initial value
0h
Set a multiplication for calculating the threshold used in the static friction failure prediction function.
Setting a small threshold multiplication for static friction failure prediction will decrease the threshold used for static friction
failure prediction. Thus, this will enable the prediction of a failure at an early stage, but will increase the possibility of
erroneously detecting a failure.
When "0" is set, the threshold multiplication is 5.
[Pr. PF40.5_Static friction failure prediction - Static friction selection]
Initial value
0h
Select a static friction setting used for static friction failure prediction.
0: Automatic setting
1: At forward rotation torque
2: At reverse rotation torque
3: 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.
[Pr. PF41_Failure prediction - Servo motor total travel distance
(FPMT)]
Initial value
0 [10 rev], [m]
Set a machine total travel distance required for determining the threshold used in the friction failure prediction function and the
machine total travel distance failure prediction function.
When the machine total travel distance exceeds 1/2 of "Failure prediction - Machine total travel distance", the threshold will be
automatically calculated for the friction failure prediction function.
When [Pr. PF34.2 Machine total travel distance - Failure prediction warning selection] is set to "1" (Enabled), if the machine
total travel distance + [Pr. PF47 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] will occur.
[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.
