5.2 Detailed list of parameters
Function
Set a servo motor total travel distance required for determining the threshold used in the friction failure
prediction function and the servo motor total travel distance failure prediction function. The setting unit can be
changed with "Failure prediction - Servo motor total travel distance unit selection" in [Pr. PF34].
When the servo motor total travel distance exceeds 1/2 of "Failure prediction - Servo motor total travel
distance unit  Failure prediction - Servo motor total travel distance", the threshold will be automatically
calculated for the friction failure prediction function.
When [Pr. PF34 Servo motor total travel distance failure prediction warning selection] is enabled, if the servo
motor total travel distance exceeds the value of "Failure prediction - Servo motor total travel distance unit 
Failure prediction - Servo motor total travel distance", [AL. F7.3 Total travel distance failure prediction
warning] will occur.
This parameter is available with servo amplifiers with software version A3 or later.
Setting range: 0 to 9999
Set a friction torque average at rated speed. This parameter is enabled only when "Manual threshold setting
(_ _ _ 2)" is set in [Pr. PF34 Friction failure prediction warning selection].
When "Automatic threshold setting (_ _ _ 1)" is set in [Pr. PF34 Friction failure prediction warning selection],
the value will be calculated automatically from the estimated friction torque at rated speed.
This parameter is available with servo amplifiers with software version A3 or later.
Setting range: -10000 to 10000
Set a friction torque standard deviation at rated speed. This parameter is enabled only when "Manual
threshold setting (_ _ _ 2)" is set in [Pr. PF34 Friction failure prediction warning selection].
When "Automatic threshold setting (_ _ _ 1)" is set in [Pr. PF34 Friction failure prediction warning selection],
the value will be calculated automatically from the estimated friction torque at rated speed.
This parameter is available with servo amplifiers with software version A3 or later.
Setting range: 0 to 20000
Set a vibration level average during servo motor operation. This parameter is enabled only when "Manual
threshold setting (_ _ _ 2)" is set in [Pr. PF34 Friction failure prediction warning selection].
When "Automatic threshold setting (_ _ _ 1)" is set in [Pr. PF34 Friction failure prediction warning selection],
the value will be calculated automatically from the estimated friction torque at rated speed.
This parameter is available with servo amplifiers with software version A3 or later.
Setting range: 0 to 10000
Set a vibration level standard deviation during servo motor operation. This parameter is enabled only when
"Manual threshold setting (_ _ _ 2)" is set in [Pr. PF34 Friction failure prediction warning selection].
When "Automatic threshold setting (_ _ _ 1)" is set in [Pr. PF34 Friction failure prediction warning selection],
the value will be calculated automatically from the estimated friction torque at rated speed.
This parameter is available with servo amplifiers with software version A3 or later.
Setting range: 0 to 20000
Function
Linear servo motor/DD motor magnetic pole detection selection
The setting value "0" will be enabled only with absolute position linear encoders.
0: Magnetic pole detection disabled
1: Magnetic pole detection at first servo-on
5: Magnetic pole detection at every servo-on
For manufacturer setting
Stop interval selection at the home position return
Set a stop interval for the dog type home position return.
The digit is enabled only for linear servo motors.
