[Pr. Pf71_Belt Failure Prediction Function Selection (Bfp)]; [Pr. Pf72_Belt Tension On Installation (Sbt)]; [Pr. Pf73_Belt Tension When Extended (Abt)]; [Pr. Pf74_Static Friction During Installation (Ssf)] - Mitsubishi Electric MELSERVO-J5 Series User Manual

[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.

[Pr. PF73_Belt tension when extended (ABT)]

Initial value
0 [0.1 N]
After the equipment is operated, set a belt tension for when the belt stretches or for when the belt is looser than at the time of
the attachment. After the belt has been attached to the equipment, the time taken for the belt to stretch depends on the belt
type. For the time taken for the belt to stretch, refer to the catalog or other documents from the manufacturer.
The belt tension deterioration prediction function is disabled when the setting is: [Pr. PF72 Belt tension on installation] < [Pr.
PF73 Belt tension when extended].

[Pr. PF74_Static friction during installation (SSF)]

Initial value
0 [0.1 %]
Set a static friction for when the belt is attached to the equipment. Set the static friction with any of the following values
estimated by the friction estimation function depending on the value of [Pr. PF71.1 Belt tension deterioration prediction friction
selection]: static friction at forward rotation, static friction at reverse rotation, or the average of the estimated frictions.
