Part name
Life guideline
Smoothing capacitor
(Note 3) 10 years
Relay
Number of power-on,
forced stop and controller forced stop times: 100 000 times
Number of on and off for STO: 1,000,000 times
Cooling fan
10,000 hours to 30,000 hours (2 years to 3 years)
(Note 1) Battery backup time
Approximately 20,000 hours (equipment power supply: off,
ambient temperature: 20 °C)
(Note 2) Battery life
5 years from date of manufacture
Note 1. The time is for using MR-J4 1-axis servo amplifier with an rotary servo motor using MR-BAT6V1SET, MR-BAT6V1SET-A, or
MR-BAT6V1BJ. For details and other battery backup time, refer to chapter 12.
2. Quality of the batteries degrades by the storage condition. The battery life is 5 years from the production date regardless of the
connection status.
3. The characteristic of smoothing capacitor is deteriorated due to ripple currents, etc. The life of the capacitor greatly depends
on ambient temperature and operating conditions. The capacitor will be the end of its life in 10 years of continuous operation in
air-conditioned environment (surrounding air temperature of 40 °C or less for use at the maximum 1000 m above sea level,
30 °C or less for over 1000 m to 2000 m).
