What are the common control unit faults and solutions for brushless motor motor manual six station internal winding machine?
Brushless motor manual six-station internal winding machine common control unit faults and solutions are as follows:
1, the controller power failure
Failure phenomenon
No display of the control unit, the entire winding machine can not start.
Controller display abnormalities, such as display confusion, lack of strokes, etc..
Failure causes
The power input line is broken, short-circuited or has poor contact, resulting in no power input to the controller.
Power adapter failure, unstable output voltage or no output.
Controller internal power circuit failure, such as capacitor damage, voltage regulator chip failure.
Solution
Check the power input line, repair the broken and short circuit points, and re-plug and unplug the plug to ensure good contact.
Measure the output voltage of the power adapter with a multimeter, and replace the power adapter if it is abnormal.
For the controller internal power circuit failure, the need for professional maintenance personnel to open the controller, testing and replacement of damaged components.
2、Motor drive failure
Failure phenomenon
Motor does not rotate, even if the drive signal is given no response.
The motor rotates abnormally, such as unstable speed, shaking, abnormal noise, etc.
Cause
The driver chip is damaged, which may be caused by over-current, over-voltage and so on.
The power tube in the driving circuit is damaged, affecting the driving current of the motor.
Loose, broken or short-circuited motor connecting wires, resulting in poor signal transmission.
Wrong setting of drive parameters, such as current limit, speed parameters and other unreasonable settings.
Solution
Use professional tools to detect the driver chip, if it is damaged, replace the same type of chip.
Check the power tube, replace the damaged power tube.
Check the motor connection line, repair or replace the damaged line, make sure the connection is firm.
Recheck and set the driving parameters, according to the motor specifications and winding process requirements for reasonable adjustment.
3、Control signal transmission failure
Fault phenomenon
There is no response to the operation panel button operation, and it is impossible to control the start, stop, speed regulation and other functions of the winding machine normally.
Sensor signals cannot be transmitted to the controller correctly, resulting in counting, positioning and other abnormal functions.
Cause
The control line is broken, short-circuited or poorly contacted, affecting the signal transmission.
Interface circuit failure, such as interface chip damage, pin oxidation, etc.
Electromagnetic interference causes signal transmission error or loss.
Solution
Check the control line, repair the line problem, re-plug the interface to ensure reliable connection.
Check the interface circuit, clean the pins and replace the damaged interface chip.
Take shielding measures for the control line, such as using shielded wires, increasing magnetic rings, etc.; arrange the lines reasonably, avoid parallel with strong electric lines to reduce electromagnetic interference.
4, program operation failure
Fault phenomenon
Program crash, reset and other abnormalities occur during the operation of the winding machine.
The winding process parameters cannot be saved or called correctly, resulting in the need to reset every time the machine is turned on.
Cause of Failure
There are loopholes or errors in the internal program of the controller, probably due to imperfect software upgrading or virus infection.
Failure of the memory chip, resulting in data not being stored and read correctly.
Insufficient hardware resources of the controller, conflict or crash when running multiple tasks.
Solution
Contact the device manufacturer to obtain new program firmware for program upgrade and repair.
Check the memory chip, replace it if damaged, and rewrite the correct parameter data.
Optimize the controller's task allocation and resource management, close unnecessary program tasks; if the hardware resources are really insufficient, consider upgrading the controller hardware.
