Servo Drive Service Life
The service life of the Servo Drive is provided below.
Consult with your OMRON representative to determine whether or not components need to be
replaced.
Aluminum electrolytic capacitors: 50,000 hours, at an ambient Servo Drive operating temperature
of 40
°
C, 80% of the rated operation output (rated torque), installed as described in this manual.
Axial fan: 30,000 hours, at an ambient Servo Drive operating temperature of 40
°
C and an ambient
humidity of 65% RH.
When using the Servo Drive in continuous operation, use a fan or air conditioner to maintain an
ambient operating temperature of 40
°
C or lower.
We recommend that the ambient operating temperature be lowered and the power ON time be
reduced as much as possible to lengthen the service life of the Servo Drive.
The service life of aluminum electrolytic capacitors is greatly affected by the ambient operating
temperature. Generally, an increase of 10
°
C in the ambient operating temperature will reduce the
capacitor life by 50%.
Aluminum electrolytic capacitors deteriorate even if the Servo Drive is stored with no power
supplied. If the Servo Drive is not used for a long time, we recommend a periodic inspection and
part replacement in five years.
If the Servomotor or Servo Drive is not used for a long time, or if they are used under conditions
worse than those described above, a periodic inspection of five years is recommended.
