What are the common control unit failures and solutions for motor motor rotor automatic six-station double flying fork winding machine?
Motor motor rotor automatic six-station double flying fork winding machine common control unit failure and solutions are as follows:
1, programmable logic controller (PLC) failure
Failure phenomenon: the winding machine can not start normally or suddenly stop during operation; the actions of the stations are not coordinated, such as flying fork rotation, rotor indexing, chuck clamping and other actions can not be accurately executed in sequence; winding parameter settings can not be saved or called, resulting in the need to re-set each time you start the machine.
Possible causes: PLC program error or loss, may be due to external interference, memory chip failure, etc.; PLC input and output interfaces are damaged, resulting in signals can not be input or output normally; power supply voltage is unstable, beyond the PLC operating voltage range, resulting in PLC work abnormally.
Solution: Use professional programming software to check and re-download the PLC program to ensure that the program is correct; check the input and output interfaces of PLC and replace them in time if they are damaged; install a voltage stabilizer to ensure that the power supply voltage input to the winding machine is stable within the range of PLC working voltage.
2、Touch screen failure
Failure phenomenon: the touch screen does not display or display abnormalities, such as splash screen, black screen, white screen and other phenomena; touch screen touch function fails, can not be parameter settings, operating instructions input, etc.; touch screen display does not match the actual operating state, such as the display of the parameter value and the actual setting of the value of different.
Possible causes: loose, poor contact or damage to the connection line of the touch screen, resulting in signal transmission interruption; touch screen itself hardware failure, such as damage to the display, touch panel failure, etc.; the driver of the touch screen is not installed or the version is not compatible, affecting the normal work of the touch screen.
Solution: Check the connection line of the touch screen, re-plug or replace the connection line; if the touch screen hardware is damaged, you need to replace the new touch screen; install or update the touch screen driver compatible with the control system of the winding machine.
3、Driver failure
Failure phenomenon: flying fork motor, rotor indexing motor can not run normally or abnormal speed, resulting in unstable winding speed or can not wind; motor jitter during operation, excessive noise and other phenomena; drive alarms, displaying over-current, over-voltage, overheating and other fault codes.
Possible causes: incorrect setting of the parameters of the drive, such as motor rated current, voltage, speed and other parameters set incorrectly; drive power module failure, can not provide normal operating voltage; motor and drive connection between the line short circuit, broken or poor contact; drive control chip damage, affecting the motor control.
Solution: Check and reset the parameters of the drive to ensure that the parameters match the motor; check the drive's power supply module, if any failure to replace in a timely manner; check the connection line between the motor and the drive, repair or replace the damaged line; if the drive's control chip is damaged, you need to replace the drive.
4、Sensor signal processing failure
Failure phenomenon: the winding machine can not accurately obtain the sensor signals, resulting in the inability to accurately control according to the sensor's feedback information, such as the position sensor signal abnormality will make the flying fork or rotor position control is inaccurate, the tension sensor signal abnormality will lead to the winding tension out of control; sensor signals from time to time, resulting in unstable work of the winding machine.
Possible causes: Damage to the electronic components in the signal processing circuit, such as capacitors, resistors, chips, etc., affecting the signal amplification, filtering, conversion and other processing; signal transmission lines are interfered with, resulting in signal distortion; the interface between the sensor and the signal processing circuit is loose or poor contact.
Solution: Use professional instruments to test the signal processing circuit, find out the damaged electronic components and replace them; take shielding measures on the signal transmission line to reduce external interference; check and tighten the interface between the sensor and the signal processing circuit.
5、Communication failure
Failure phenomenon: the various control units of the winding machine can not be normal communication, such as PLC and touch screen, drive data interaction, resulting in the system can not work together; communication interruptions, the winding machine may be part of the functional failure or error action.
Possible causes: communication line damage, disconnection or poor contact; communication protocol setting error, resulting in communication data between the control units can not be correctly recognized and parsed; communication interface hardware failure, affecting the communication signal sending and receiving.
Solution: Check the communication line, repair or replace the damaged line; ensure that the communication protocol setting of each control unit is consistent, and correctly configure the communication parameters; check the communication interface, and replace it in time if there is any failure.
