8.8 Servo amplifier life diagnosis function

You can check the cumulative energization time and the number of on/off times of the inrush relay based on
the data in the servo amplifier. This function gives an indication of the replacement time for parts of the servo
amplifier including a capacitor and a relay before they malfunction. The information of the servo amplifier life
diagnosis function can be obtained with the following objects.

number
Refer to chapter 4 of "MR-J4-_TM_ Servo Amplifier Instruction Manual" to start the system.
Rotate the servo motor with a controller. (One-touch tuning cannot be performed if the servo
motor is not operating.)
Write a value corresponding to the response mode (High mode, basic mode, or Low mode) to
perform in One-touch tuning mode (P11600) during servo motor driving to perform one-touch
tuning.
Gains and filters will be adjusted automatically. During one-touch tuning, the progress can be
checked with One-touch tuning status (P11601).
Check whether one-touch tuning is completed normally with One-touch tuning Error Code
(P11604). When one-touch tuning is completed normally, the parameters will be set
automatically. Refer to section 6.2 of "MR-J4-_TM_ Servo Amplifier Instruction Manual" for the
parameters that are set automatically.
After a tuning error is returned, take the appropriate action according to section 6.2.2 (4) of "MR-
J4-_TM_ Servo Amplifier Instruction Manual".
Check the tuning result.
If the tuning result is not satisfactory, you can return the parameter to the value before the one-
touch tuning or the initial value using One-touch tuning Clear (P11603).
