First, the fault phenomenon.
During the use of Sanyo servo drive, various fault phenomena may occur. Among them, common faults include motor not rotating, motor speed inaccurate, motor heating, drive alarm, etc. These faults can be caused by circuit board cable detachment, governor failure, motor bearing damage, etc.
2. Failure analysis.
In view of the above fault phenomena, we can perform the following analysis:
1.The motor does not rotate.
If the Sanyo servo drive is unable to control the rotation of the motor, it may be caused by a detachment of the circuit board cable or a faulty governor. At this time, we need to check whether the circuit board cable is falling off and whether the governor is working properly.
2.The motor speed is not accurate.
If the motor speed is not accurate, it may be caused by damage to the motor bearing or incorrect driver parameter setting, etc. At this point, we need to check whether the motor bearing is damaged and reset the drive parameters.
3.The motor heats up.
If the motor heats up severely during use, it may be caused by excessive load or internal failure of the motor. At this point, we need to check if the load is too large and if there is a fault inside the motor.
4.Drive alarms.
If there is an alarm prompt in the driver, it may be caused by the circuit board cable falling off, governor failure, motor bearing damage, etc. At this time, we need to check whether the circuit board cable is falling off, whether the governor is working normally, whether the motor bearing is damaged, etc.
3. Fault repair.
In view of the above fault analysis, we can take the following remedial measures:
1.For the fault that the motor does not rotate, if it is found that the circuit board cable falls off, it needs to be replaced in timeIf the governor is faulty, you need to replace it with a new one.
2.For the fault of inaccurate motor speed, it is necessary to check whether the motor bearing is damaged, and if it is damaged, it needs to be replaced in timeAt the same time, the drive parameters are reset to ensure that the motor speed is accurate.
3.For faults where the motor heats up, it is necessary to check whether the load is too large, and if so, it is necessary to reduce the load;At the same time, check whether there is a fault inside the motor, and repair it in time if necessary.
4.For the fault of the driver alarm, it is necessary to check whether the circuit board cable is falling off, whether the governor is working normally, whether the motor bearing is damaged, etc. According to the results of the inspection, corresponding repair measures will be taken.
4. Preventive measures.
In order to avoid the failure of the Sanyo servo drive, the following precautions can be taken:
1.Regularly inspect and maintain the Sanyo servo drive to ensure that it is working properly.
2.Pay attention to the load situation during use and avoid overload use.
3.Regularly inspect and lubricate the motor bearing to avoid bearing damage.
4.Regularly inspect and debug the governor to ensure that it is working properly.
5.Pay attention to the safety operation procedures during use to avoid failures caused by human factors.
