8 Inspection
It is recommended to check the following four items after motor operation. If any
failure is found, stop the operation, and please contact your local sales office.
Inspection items
• Check if abnormal noise is produced from the motor bearing section (ball
bearing).
• Check if abnormal noise is produced from the gearhead bearing (ball bearing) and
gear meshing section.
• Check if the motor cable is damaged or stressed. Also, check if the connections
with the driver are loosened.
• Check if there is any misalignment between motor (gearhead) output and load
shafts.
• Check if dust is deposited on the driver.
Note
Conduct the insulation resistance measurement or withstand voltage test
separately on the motor and the driver.
