When replacing equipment [G] [B]
When replacing the equipment, set the servo motor total travel distance offset to obtain the accurate total travel distance for
the device and have the servo motor total travel distance continue from the previous distance value. Perform the actions
shown in the following table when replacing the equipment.
Equipment being replaced
Servo motor (the servo amplifier and the equipment
are not replaced)
Servo amplifier (the servo motor and the equipment
are not replaced)
Servo amplifier and servo motor (the equipment is
not replaced)
Encoder (the servo motor, the servo amplifier, and
the equipment are not replaced)
Equipment such as ball screws and guidelines (the
servo motors and the servo amplifiers are not
replaced)
*1 When the servo motor total travel distance cannot be checked due to a servo amplifier malfunction, set "0" in [Pr. PF47 Servo motor total
travel distance offset], or set the value of the servo motor total travel distance at the last check before the malfunction.
When replacing equipment [A]
When replacing the equipment, set the servo motor total travel distance offset to obtain the accurate total travel distance for

*1 When the servo motor total travel distance cannot be checked due to a servo amplifier malfunction, set "0" in [Pr. PF58 Servo motor total
travel distance offset], or set the value of the servo motor total travel distance at the last check before the malfunction.
Action
None
Step 1. Check the servo motor total travel distance before replacement.
Step 2. After replacement, set the servo motor total travel distance before the replacement in [Pr. PF47
Servo motor total travel distance offset].
Step 1. Check the servo motor total travel distance before replacement.
Step 2. After replacement, set the servo motor total travel distance before the replacement in [Pr. PF47
Servo motor total travel distance offset].
None
After replacement, reset the servo motor total travel distance by setting "2" (servo motor total travel
distance reset) in [Pr. PF34.2] followed by cycling the power or performing either of the software reset or
controller reset.
Action
None
Step 1. Check the servo motor total travel distance before replacement.
Step 2. After replacement, set the servo motor total travel distance before the replacement in [Pr. PF58
Servo motor total travel distance offset].
Step 1. Check the servo motor total travel distance before replacement.
Step 2. After replacement, set the servo motor total travel distance before the replacement in [Pr. PF58
Servo motor total travel distance offset].
None
After replacement, reset the servo motor total travel distance by setting "2" (servo motor total travel
distance reset) in [Pr. PF51.2] followed by cycling the power or performing either of the software reset or
controller reset.
