Total travel distance failure prediction function
Outline [G] [B]
The total travel distance failure prediction function can check the total travel distance of devices and that of the servo motor
after the shipment.
The servo motor total travel distance indicates the cumulative number of rotations or total travel distance of the servo motor.
The servo motor total travel distance is intended to be used as a guide for the timing of replacement and maintenance of the
servo motor and mechanical parts in the equipment.
The servo amplifier has the data of the servo motor total travel distance. Therefore, perform settings on the servo amplifier
such as offsetting and resetting after replacing the equipment parts.
By setting [Pr. PF34.2 Servo motor total travel distance failure prediction warning selection], when the servo motor total travel
distance exceeds the threshold, a warning is output by the servo amplifier and the servo motor and mechanical parts failure
can be predicted in advance.

Precautions [G] [B]
• In the total travel distance failure prediction function, the servo motor total travel distance will be calculated when [Pr.
PF34.0] is set to a value other than "0" (disabled), or [Pr. PF34.2] is set to "1" (enabled).
Precautions [A]
• In the total travel distance failure prediction function, the servo motor total travel distance will be calculated when [Pr.
PF51.0] is set to a value other than "0" (disabled), or [Pr. PF51.2] is set to "1" (enabled).
Total travel distance reading method [G] [B]
The servo motor total travel distance can be read with the engineering tool (MR Configurator2) via network or USB
connection. The value set in [Pr. PF47 Servo motor total travel distance offset] is added to the read servo motor total travel
distance.
■When reading the total travel distance via the network [G]
Specify and read the target object. Refer to the following for details of the objects.

■When reading the total travel distance with an engineering tool (MR Configurator2)
Select the servo motor total travel distance on the machine diagnosis screen and click "Read". The servo motor total travel
distance at the time of clicking "Read" is displayed, and can be checked and compared with the threshold of the servo motor
total travel distance. In addition, the read servo motor total travel distance can be saved on the machine diagnosis screen.
The displayed range is from 0 to 42949672950. If it exceeds this range, it is clamped at the maximum value.
