Inspection
It is recommended that periodic inspections be conducted for the items listed below after each
operation of the motor.
If an abnormal condition is noted, discontinue any use and contact your nearest office.
During inspection:
• Are any of the motor mounting screws loose?
• Check for any unusual noises in the motor’s bearings (ball bearings) or other moving parts.
• Are the motor’s output shaft (or gear output shaft) and load shaft out of alignment?
• Are there any scratches, signs of stress or loose driver connections in the motor cable?
• Check for a blocked opening of the driver case.
• Are any of the driver mounting screws or power-connection terminal screws loose?
• Are there any strange smells or appearances in the power elements and filtering capacitors
within the driver?
Note
The driver uses semiconductor
elements, so be extremely
careful when handling them.
Static electricity may damage the
driver.
