1 SERVO MOTOR MAINTENANCE
Generally, αis/αi series AC servo motors have no parts that wear off or
that must be replaced periodically, unlike DC servo motors, which have
brushes that must be replaced periodically.
However, you should perform periodic maintenance for servo motors
so as to keep their initial performance as long as possible and to prevent
breakdowns. AC servo motors have precision sensors. Their incorrect
use or damage caused during transportation or assembling can result in
breakdowns or accidents. We recommend that you inspect the servo
motors periodically according to the descriptions given below.
