Servo amplifier life diagnosis function
The servo amplifier life diagnosis function is a function to diagnose the service life of the servo amplifier itself. The
approximate service life of the servo amplifier being used can be determined. The servo amplifier life diagnosis function
features the following functions.
Cumulative energization time function
Displays the cumulative time that the control circuit power supply of the servo amplifier has been on for, starting at the time of
shipment.
• To acquire the energization time, MR Configurator2 or a controller is required.
Precautions
• The interval for recording the cumulative value of energization time is 10 minutes. When turning the servo amplifier off/on
frequently within this time, there is a possibility that the cumulative value of energization time deviates from the actual
value.
• This function displays the approximate service life. Since the service life varies by the method of use and environmental
conditions, replace the servo amplifier after discovering an error.
Setting method
No setting is required to use the cumulative energization time function. The servo amplifier always measures the energization
time.
Service life check method

How to check with MR Configurator2
When confirming the cumulative energization time value using MR Configurator2, open the life diagnosis screen of MR
Configurator2. The cumulative energization time of the servo amplifier can be checked from the life diagnosis screen of MR
Configurator2.

How to check with objects [G] [WG]
When confirming the cumulative energization time value with the controller, obtain the following object.
