Servo amplifier life diagnosis function

The servo amplifier life diagnosis function is a function to diagnose the life of the servo amplifier itself. The approximate 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 life. Since the 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.
Method of checking life
■Method of using 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.
■Method of using objects [G] [WG]
When confirming the cumulative energization time value with the controller, obtain the following object.
