Error and Maintenance
Servo Drive Limit
Œ
The limit for units is listed below.
Aluminum electrolytic capacitors:
28,000 hours
(at an ambient driver 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.)
Œ
When using the driver in continuous operation, use fans or air conditioners to maintain an ambient
temperature below 40
°
C.
Œ
We recommend that ambient temperature and the power supply ON time be reduced as much as
possible to lengthen the service life of the driver.
Œ
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 limit by 50%.
Œ
The aluminum electrolytic capacitors deteriorate even when the Servo Drive is stored with no
power supplied. If the driver is not used for a long time, we recommend a periodic inspection and
replacement schedule of 5 years.
Œ
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.
Œ
Upon request, OMRON will examine the Servo Drive and Servomotor and determine if a
replacement is required.
