5.1 Motor Inspection
The procedures for simple daily maintenance of the servomotor are shown in Table 5.1 .
Because AC servomotors are brushless, simple daily inspection is sufficient. The inspection
periods in the table are standard scales. Determine the usage conditions and environment, and
then decide an appropriate inspection period.
Do not disassemble the servomotor for maintenance/inspection. Contact your Yaskawa
representative or sales office if the servomotor is to be disassembled.
