[Pr. PF56_Vibration failure prediction - Average characteristics
(VAV)]
Initial value
0 [0.1 %]
Set a vibration level average during servo motor operation.
This servo parameter is enabled when [Pr. PF51 Friction failure prediction warning selection] is set to "2" (enabled (manual
threshold setting)).
When [Pr. PF51 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.

[Pr. PF57_Vibration failure prediction - Standard deviation (VSD)]

Initial value
0 [0.1 %]
Set the vibration level standard deviation during servo motor operation.
This servo parameter is enabled when [Pr. PF51 Friction failure prediction warning selection] is set to "2" (enabled (manual
threshold setting)).
When [Pr. PF51 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.

[Pr. PF58_Servo motor total travel distance offset (TMO)]

Initial value
0 [10 rev], [m]
Set an offset value for servo motor total travel distance.
After the equipment is replaced, set this servo parameter.

[Pr. PF66_Gear setting for backlash estimation (BLG)]

Initial value
00000000h
[Pr. PF66.0-3_Gear for backlash estimation - Numerator]
Initial value
0000h
Set the gear ratio numerator of the gear connected to the servo motor in hexadecimal. If multiple gears are connected to the
servo motor, set the gear ratio up to where the load is applied.
If the gear ratio numerator and the denominator cannot be expressed by numbers up to "2
set a value equal to or less than "2
[Pr. PF66.4-7_Gear for backlash estimation - Denominator]
Initial value
0000h
Set the gear ratio denominator of the gear connected to the servo motor in hexadecimal. If multiple gears are connected to the
servo motor, set the gear ratio up to where the load is applied.
If the gear ratio numerator and the denominator cannot be expressed by numbers up to "2
set a value equal to or less than "2
