[Pr. PF46_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. 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.

[Pr. PF47_Servo motor total travel distance offset (TMO)]

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

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

Initial value
00000000h
[Pr. PF66.0-3_Gear ratio 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 ratio 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

[Pr. PF67_Backlash nominal value (BLN)]

Initial value
0 [0.01 degree]
Set a backlash nominal value required for setting a threshold used for gear failure prediction. Input a backlash value
presented by the manufacturer of the gear connected to the servo motor.
When [Pr. PF66.0-3 Gear ratio for backlash estimation - Numerator] or [Pr. PF66.4-7 Gear ratio for backlash estimation -
Denominator] is set to "0", input the backlash nominal value after converting the value into the rotation angle on the servo
motor side.
When [Pr. PF66.0-3] or [Pr. PF66.4-7] is set to a value other than "0", input a value considering the gear ratio for backlash
estimation.
When "0" is set, even if backlash estimation is performed, [AL. 0F7 Machine diagnosis warning] will not be generated.
