Solutions for problems encountered
A good-conditioned servomotor operating in an ideal environment can have a very long life span. We are talking about thirty years. During these years, he may encounter troubles that require a specialist's intervention. Here are some examples of problems that can happen:
Faulty encoder: When you see the error codes AC9 or AC90 [error code on Yaskawa Products] on your servo-drive, there is a strong likelihood that the encoder is defective.
Brake that sticks: when the brake sticks, the motor must use more current in order to do the same work as in normal time. In this case, your servo-drive may present the error code Over Current A10 [error code on Yaskawa products].
Motor overheating: There may be several causes for an overheating engine. Prematurely worn bearings, damaged brake or improper parameterisation of the servomotor in the servo-drive when the servomotor configuration does not correspond to the correct application of the servomotor.
Motor Vibration: When the motor is unbalanced, it starts to vibrate. Without immediate maintenance, the vibrations will become stronger, which will damage the servomotor. Worn bearings and bearing cages can cause vibration. The more vibration, the more the encoder is likely to get damaged. When the actuator is noisy, there is a good chance that it will be unbalanced.
Broken motor Connector: In addition to damaging the motor, this can also damage the servo-drive by causing a short circuit.
Unplugged Actuator Connector: A connector that is not plugged into the servomotor, can create a warm up and cause faults such as over Current A10 [error code on Yaskawa products]. This could also damage the servo-drive by causing a short circuit.
Accumulation of metal dust on the encoder: When the brake and bearings wear out, they can send metal dust to the encoder. This may affect the readings of the encoder.
