1. Vibration phenomenon of servo motor maintenance.
Vibration may occur when the machine tool is running at high speed, and an overcurrent alarm will be generated at this time. The vibration of machine tool generally belongs to the problem of speed, so we should look for the problem of speed ring.
2. the phenomenon of reducing maintenance torque of servo motor.
When the servo motor runs from rated blocking torque to high speed, it is found that the torque will suddenly decrease, which is due to the heat dissipation damage and machinery of the motor winding.
Partial fever. At high speed, the temperature rise of the motor becomes larger, so the load of the motor must be checked before using the servo motor correctly.
3. The phenomenon of maintenance and movement of servo motor.
The phenomenon of movement occurs during feed, and the speed measurement signal is unstable, such as cracks in the encoder and poor contact with the terminal. When the movement occurs by the square.
The moment of commutation between the movement in the opposite direction and the movement in the opposite direction is generally due to the excessive reverse clearance of the feed drive chain or the excessive servo drive gain.
