What are the common control unit faults and solutions for series excitation motor motor stator winding machine?  

The common control unit faults and solutions for series excitation motor motor stator winding machine are as follows:

1、Error in parameter setting

Failure phenomenon: the winding machine can not be started normally or run abnormally, such as the number of coils, speed and other parameters are mistakenly set to 0 or set unreasonably, resulting in the equipment can not be in accordance with the expected requirements of the winding work2 .

Solution: After setting the parameters and before starting the machine, double-check whether the winding parameters are correct, and make sure that the number of coils, speed, wire diameter and other parameters are in line with the actual winding requirements2 .

2、Electromagnetic interference fault

Failure phenomenon: Frequent shutdown of the winding machine, the set parameters can not be saved or confused, affecting the normal operation of the equipment.

Solution: Supply power to the winding machine separately or install capacitors to reduce the impact of electromagnetic interference on the control unit.

3、Grid fluctuation fault

Failure phenomenon: when the power grid fluctuation is too large, the controller has no output signal, the inverter over-voltage or under-voltage alarm, resulting in the winding machine can not work normally.

Solution: Add an AC voltage regulator to the power input of the winding machine to stabilize the input voltage and ensure that the equipment works within the rated voltage range.

4、External signal input abnormal fault

Failure phenomenon: the position of the wire system sensors and operating panel buttons and other external signal input abnormality, the controller can not start working normally, or display error codes.

Solution: Check whether the connection between the sensor and the operating panel button is firm and whether the signal transmission is normal. If loose or damaged, repair or replace them in time; for abnormal sensor signals, it is necessary to further check whether the sensor itself is faulty and deal with it accordingly.

5、Control system alarm failure

Failure phenomenon: In the daily operation process, due to the accumulation of data over a long period of time and high-intensity operation, the control system of the winding machine may appear occasional alarm.

Solution: Analyze and investigate the alarm information in time against the processing method in the instruction manual of the winding machine, find out the cause of the fault and eliminate it.

6、Main control board failure

Failure phenomenon: When the main control board of the control unit fails, the winding machine may have various abnormal phenomena, such as unable to start, run out of control, abnormal parameter display.

Solution: In the case of ensuring that no further damage, the main control board with a spare replacement is suspected of having problems with the main control board, is an effective way to accurately locate the point of failure. Sometimes it will be faster to diagnose the fault by replacing the same type of main control board with other winding machines.
