Common causes and solutions of faults in iron core winding machines!

1、 The positive and negative pole suction plates of the iron core winding machine have not yet reached the supply guide plate before releasing the pieces.
Reason: ① Vacuum damage, incorrect insertion of trachea (front, back or left, right); ② Polar suction confirms poor contact of the sensor.
Solution: ① Replace the trachea; ② Use a multimeter to check if the signal wire is broken and if the sensor is damaged → replace the sensor.
2、 Iron core winding machine malfunction: Automatic mode, pressing the start button is ineffective.
Reason: ① The automatic/manual conversion button or start button is broken; ② The length parameter of the diaphragm is not set.
Solution: ① Replace the switch button; ② Set the parameters.
3、 Iron core winding machine malfunction: positive CV motor does not rotate.
Reason: ① The jog parameter setting is too small; ② Driver parameters not set properly or in alarm state; ③ The motor power cord is not properly connected.
Solution: ① Increase the parameters; ② Set the parameters or shut down and restart → replace the drive; ③ Connect the power cord properly.
4、 Iron core winding machine malfunction: The positive and negative poles RB do not rise after the suction plate descends.
Reason: Pole suction confirms that the sensor has input but no output.
Solution: Use a multimeter to check if the output line is conductive → replace the sensor.
5、 Iron core winding machine malfunction: Negative CV motor overheating alarm.
Reason: ① The setting current parameters of the thermal relay are not set properly or the thermal relay is damaged; ② The bearings or coils on the internal gears of the CV motor are damaged and overloaded.
Solution: ① Set the current setting parameters or replace the thermal relay; ② Replace the motor.
6、 Iron core winding machine malfunction: abnormal diaphragm unwinding motor.
Reason: ① Driver abnormal alarm; ② The power cord is disconnected.
Solution: ① Shut down and restart; ② Connect the power cord properly.
7、 Iron core winding machine malfunction: The speed of the diaphragm unwinding motor is too fast and cannot be adjusted slowly.
Reason: ① The potentiometer is broken; ② The speed control circuit board is damaged.
Solution: ① Use a multimeter to check if the potential is damaged first → Replace the potentiometer ② Replace the circuit board.
8、 Iron core winding machine malfunction: The tension claw has reached the lower limit, and the sensor has sensed it but cannot reset or disconnect.
Reason: ① Tension claw linkage confirmation sensor has input but no output; ② The sensor signal line is connected in reverse between normally open and normally closed.
Solution: ① First use a multimeter to detect a broken signal line → replace the sensor; ② Swap the signal line.
9、 Iron core winding machine malfunction: The winding needle motor does not rotate.
Reason: ① Motor driver power switch tripped; ② The setting of the tension claw variable speed parameter is too small; ③ The tension claw retreat position parameter is set too high; ④ Driver damage; ⑤ The motor power cord has come loose.
Solution: ① Close the power switch; ② Adjust parameters; ③ Adjust parameters; ④ Replace the drive; ⑤ Connect the power cord properly.
10、 Iron core winding machine malfunction: Negative CV motor does not rotate.
Reason: ① Fiber optic induction is not set properly and has been connected; ② The main contact of the thermal relay is damaged; ③ The starting capacitor is damaged.
Solution: ① Set the fiber parameters properly; ② Replace the thermal relay; ③ Replace the capacitor.
11、 Iron core winding machine malfunction: The product discharge motor does not rotate.
Reason: ① Incorrect connection or detachment of motor power cord; ② The motor is stuck and unable to rotate ③ The internal gear bearings of the motor are damaged.
