 ABB Robot Servo Motor repair do azimuth control operation report overspeed fault, how to deal with it?

Once the servo run signal is connected, it will break out: check whether the wiring of servo motor power cable and encoder cable is correct and whether there is damage.

After inputting the pulse command, it occurs during high-speed operation: the pulse frequency output by the controller is too high, and the correction program adjusts the frequency of the pulse output; The electronic gear ratio is set too large; The servo gain setting is too large. Adjust the servo gain manually or actively from the beginning



5. ABB Robot Servo motor repairs several faults without overload with load. How to deal with them?



If the servo run signal is connected and no pulse is sent, it will occur:

Check the servo motor power cable wiring to see if there is poor contact or cable damage; If it is a servo motor with a brake, the brake must be turned off; Whether the speed loop gain is set too large; Whether the integration time constant of the speed loop is set too small.



If the servo only occurs during operation:

Whether the azimuth loop gain is set too large; Whether the positioning completion amplitude is set too small; Check whether the servo motor shaft is locked and adjust the machine from the beginning.



6. How to deal with abnormal sound or vibration when ABB Robot Servo motor repairs several faults?

Servo wiring:

Check whether the power cable, encoder cable, control cable and cable are damaged; Check whether there is interference source near the control line and whether it is parallel to or too close to the nearby high current power cable; Check whether there is any sudden change in the potential of the grounding terminal to ensure excellent grounding.



Servo parameters:

The servo gain setting is too large, and it is suggested to manually or actively adjust the servo parameters from the beginning; Acknowledge the setting of the time constant of the speed response filter. The initial value is 0, and the set value can be tested to increase; The electronic gear ratio setting is too large, and it is suggested to restore to the factory setting; Resonance of servo system and mechanical system, test and adjust the frequency and amplitude of notch filter.



Mechanical system:

The coupling connecting the motor shaft and the equipment system is offset, and the mounting screws are not tightened; Poor engagement of pulley or gear will also lead to load torque change. Test the no-load operation. If the no-load operation is normal, check whether the joint part of the mechanical system is abnormal; Confirm whether the load inertia, torque and speed are too large, and test the no-load operation. If the no-load operation is normal, reduce the load or replace the driver and motor with larger capacity.
