1.8 Maintenance and Inspection of the Servo Unit
Servo systems are made up of many parts, and only when all parts are functioning properly can the equipment perform
its proper function. Among mechanical parts and electronic parts, certain parts need to be maintained depending on the
conditions of use, and they must be regularly checked or replaced according to their service life to ensure that the servo
motor and servo driver can operate normally for a long time.
1.8.1 Servo Motor Overhaul
Since AC servo motors are not equipped with brushes, only routine and simple maintenance is required. The maintenance
period in the table is a general standard. Please judge according to the usage and environment and decide the most
appropriate maintenance period..
Table 1-1 Servo motor maintenance breakdown
1.8.2 Servo Drive Maintenance
