[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.

[Pr. PF71_Belt failure prediction function selection (BFP)]

Initial value
00000000h
[Pr. PF71.0_Belt tension deterioration prediction function selection]
Initial value
0h
0: Disabled
1: Execute only belt tension estimation
2: Belt tension deterioration prediction function enabled
After the equipment goes into full-scale operation, enable the belt tension deterioration prediction function.
[Pr. PF71.1_Belt tension deterioration prediction friction selection]
Initial value
0h
Select a static friction setting used for belt tension deterioration 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. PF72_Belt tension on installation (SBT)]

Initial value
0 [0.1 N]
Set a belt tension for when the belt is attached to the equipment. The servo parameter indicates the reference belt tension
threshold used in the belt diagnosis function.
