App. 4.6.2 Parts having service lives
Service lives of the following parts are listed below. However, the service lives vary depending on operation
and environment. If any fault is found in the parts, they must be replaced immediately regardless of their
service lives. For parts replacement, please contact your local sales office.
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 reach the end of its life in 10 years of continuous
operation in normal air-conditioned environment (40 °C surrounding air temperature or less).
App. 4.7 Transportation and storage
CAUTION
Transport the products correctly according to their mass.
Stacking in excess of the limited number of product packages is not allowed.
Do not hold the front cover to transport the servo amplifier. Otherwise, it may
drop.
Install the product in a load-bearing place of servo amplifier and servo motor in
accordance with the Instruction Manual.
Do not get on or put heavy load on the equipment.
For detailed information on the option battery’s transportation and handing refer to
app. 2 and app. 3.
