What are the common control unit failures and solutions for brushless motor motor automatic rotor bearing press-in machine?
The control unit of brushless motor motor automatic rotor bearing press-in machine is used to accurately regulate the various actions and parameters of the equipment, and once there is a failure, it will affect the normal operation of the equipment. The following is to introduce you to the common faults and corresponding solutions:
1、Power failure
l Failure phenomenon
The control unit is completely unresponsive, the equipment can not be started, the display does not show.
The power indicator flashes or displays abnormally, indicating that the power supply is unstable.
l Failure causes
External power supply problems, such as power sockets are dead, blown fuses, power cord damage.
Control unit internal power module failure, such as filter capacitor damage, transformer failure.
The power switch is damaged and cannot conduct the circuit normally.
l Solution
Check the external power supply and replace the damaged socket, fuse or power cord.
Use professional instruments to test the power module and replace the faulty components.
Replace the damaged power switch.
2、Display Failure
l Failure phenomenon
The display screen is black, splash screen, can not display information normally.
The displayed data is inaccurate, such as pressure, displacement and other parameters are displayed incorrectly.
l Failure causes
The display connecting wire is loose, detached or damaged, resulting in signal transmission interruption.
The display driver chip is faulty and cannot process the display signal correctly.
Failure of software, resulting in abnormal display interface.
Solution
Check and re-plug the display connection cable, and replace it if it is damaged.
Test the display driver chip and replace it if it is faulty.
Reset or upgrade the control unit software and repair the software failure.
3、Parameter Setting Failure
l Failure phenomenon
Can not normally set the press-in parameters, such as press-in force, press-in depth, etc..
The set parameters can not be saved, restored to the default value after restart.
l Fault cause
The operation keys are damaged, and the parameters cannot be input accurately.
The memory chip of the control unit is faulty and the data cannot be saved normally.
The software program has loopholes, resulting in abnormal parameter setting function.
l Solution
Replace the damaged operation keys.
Test the memory chip and replace it if it is faulty.
Contact the equipment manufacturer to obtain a software patch or upgrade program to repair the software vulnerability.
4、Logic control failure
l Failure phenomenon
The device cannot run according to the preset logic program, such as wrong press-in sequence and uncoordinated action.
The device suddenly stops or shows abnormal action under automatic operation mode.
l Cause
The logic circuit of the control unit fails, resulting in signal processing error.
Inaccurate or missing signals fed back from sensors affect the judgment of the control unit.
The logic algorithm of the software is faulty, and it cannot control the action of the equipment correctly.
l Solution
Use professional instruments to detect the logic circuit and replace the faulty components.
Check the sensors and their connection lines to ensure that the sensors work properly and the signal transmission is stable.
Debug and correct the logic algorithm of the software, and upgrade the software if necessary.
5、Communication failure
l Fault phenomenon
The control unit and external devices (such as the host computer, sensors, etc.) can not communicate normally.
The data transmission is wrong or lost, resulting in abnormal operation of the equipment.
l Failure causes
The communication interface is damaged, such as the serial port, network port, etc. is faulty.
Communication protocol mismatch, resulting in data not being parsed correctly.
The communication line is interfered or damaged, affecting the signal transmission.
l Solution
Check the communication interface and replace the damaged interface module.
Check the communication protocol settings to ensure that the control unit and external devices use the same protocol.
Shield and reinforce the communication line, and replace the line in time if it is damaged.
