1.7 Maintenance and Inspection of Servo Drive
The servo system is made up of many parts. The equipment performs its functions only when all

maintained depending on the conditions of use. It must be regularly checked or replaced according
to the service-time to ensure that the servo motor and servo drive can operate normally for a long
