Servo Drive Life Expectancy - Omron OMNUC G5 R88M-K series User Manual

Servo Drive Life Expectancy

 The life expectancy for units is listed below.
Aluminum electrolytic capacitors:
(at an ambient drive operating temperature of 55C, constant output of rated torque, constant
output of rated rotation 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 operation
conditions.)
 When using the Servo Drive in continuous operation, use fans or air conditioners to maintain an
ambient temperature below 40C.
 We recommend that ambient temperature and the power supply ON time be reduced as much as
possible to lengthen the service life of the drive.
 The limit of aluminum electrolytic capacitors is greatly affected by the ambient operating
temperature. Generally, an increase of 10C in the operating ambient temperature will reduce
capacitor service life by 50%.
 For example, when the ambient operating temperature is 25C, the life expectancy will be as
follows:
Life Expectacy (at 25°C) = Life Expectacy (at 55°C) × 2
 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 a periodic inspection
and replacement schedule of 5 years.
 If the Servomotor 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 schedule of 5 years is
recommended.
 Upon request, OMRON will examine the Servo Drive and Servomotor and determine if a
replacement is required.
