12 Troubleshooting and Maintenance
12 - 36
G5-series Linear Motors/Servo Drives With Built-in EtherCAT Communications
•
The lifetimes for the different drive parts are given below.
•
When using the Servo Drive in continuous operation, use fans or air conditioners to maintain the
ambient temperature below 40°C.
•
We recommend that the ambient temperature and the power supply ON time be reduced as much as
possible to lengthen the service life of the Servo Drive.
•
The limit of aluminum electrolytic capacitors is greatly affected by the operating ambient temperature.
Generally, an increase of 10°C in the operating ambient temperature will reduce capacitor service life
by 50%.
For example, when the operating ambient temperature is 25°C, the life expectancy will be as follows:
•
The aluminum electrolytic capacitors deteriorate even when the Servo Drive is stored with no power
supplied. If the Servo Drive is not used for a long time, we recommend periodic inspection and a part
replacement period of 5 years.
•
If the motor or Servo Drive is not to be used for a long time, or if they are to be used under conditions
worse than those described above, a periodic inspection period of 5 years is recommended.
•
Upon request, OMRON will inspect the Servo Drive and motor and determine if part replacement is
required.
12-5-2 Servo Drive Life Expectancy
Servo Drive Life Expectancy
Aluminum electrolytic capacitors:
28,000 hours
(at an ambient drive operating temperature of 55ºC, constant output at rated force, constant output at rated
speed, and installation as described in this manual)
Axial-flow fan:
10,000 to 30,000 hours
(The limit depends on the operating conditions.)
Inrush current prevention relay:
Approx. 20,000 operations
(The limit depends on the operating conditions.)
= Life expectancy at 55°C × 2
Life expectancy at 25°C
= 224,000 hours
