[Pr. Pf68_Backlash Threshold Multiplication (Bltt)]; [Pr. Pf69_Static Friction Failure Prediction - Average Characteristics (Spav2)]; [Pr. Pf70_Static Friction Failure Prediction - Standard Deviation (Spsd2)] - Mitsubishi Electric MELSERVO-J5 MR-J5-G Series User Manual

[Pr. PF68_Backlash threshold multiplication (BLTT)]

Initial value
0
Set a threshold multiplication to set a threshold used for gear failure prediction. The threshold used for the gear failure
prediction is expressed by the following equation.
Backlash threshold = [Pr. PF67 Backlash nominal value]/100 × [Pr. PF68 Backlash threshold multiplication]/10
When "0" is set, a value twice the value of [Pr. PF67 Backlash nominal value]/100 is set as the backlash threshold.
When the backlash threshold is "0", even when the backlash estimation is performed, [AL. 0F7 Machine diagnosis warning]
will not be generated.
[Pr. PF69_Static friction failure prediction - Average
characteristics (SPAV2)]
Initial value
0 [0.1 %]
Set a static friction torque average.
This servo parameter is enabled when [Pr. PF34.5 Static friction failure prediction - Warning selection] is set to "2" (Manual
threshold setting).
When [Pr. PF34.5 Static friction failure prediction - Warning selection] is set to "1" (Automatic threshold setting), the value will
be calculated automatically from the estimated static friction torque.
[Pr. PF70_Static friction failure prediction - Standard deviation
(SPSD2)]
Initial value
0 [0.1 %]
Set a standard deviation of static friction torque.
This servo parameter is enabled when [Pr. PF34.5 Static friction failure prediction - Warning selection] is set to "2" (Manual
threshold setting).
When [Pr. PF34.5 Static friction failure prediction warning selection] is set to "1" (Automatic threshold setting), the value will be
calculated automatically from the estimated friction torque at rated speed.
