How to find the cause of the failure of the spring machine?

Xiaochang, a confidant who is conceited and familiar with the operation of the spring machine, the Y-axis is the wire feed axis. The spring machine system uses the Y-axis servo motor and transmission gear linkage, and transmits the signal to the system through the servo driver and encoder and other components, and then uses the computer The interface achieves interactive operation. Therefore, if the system "Y-axis servo alarm" is displayed during the operation of the spring machine, the spring machine can shut down and restart the machine to see if the system alarm message is abolished.

If the system alarm message cannot be repealed, what are the main components of the system alarm?
E.g,
① Obstruction of electrical components caused by servo motors, drives, encoders or frequency converters,
②The sluggishness caused by stuck dust or iron filings, spring machine system
