What are the common control unit faults and solutions for brushless motor motor manual stator slot paper machine?
Brushless motor motor manual stator slot paper machine common control unit faults and solutions are as follows:
1, the controller power failure
Failure phenomenon
The control unit has no display, the whole device can not start, the motor does not run.
The controller appears to work intermittently, sometimes normal, sometimes dead or unresponsive.
Solution
Check whether the power socket is energized, whether the power cord is broken or has poor contact, if there is any problem, replace the power cord or repair the socket.
Measure whether the power input voltage is within the range required by the controller, if the voltage is too low or too high, check the power supply line or use a voltage regulator for voltage adjustment.
Check the power module inside the controller to see if there are obvious signs of damage such as capacitor bulging, burnt components, etc. If so, replace the damaged components or the entire power module.
2, motor drive failure
Failure phenomenon
The motor can not rotate, or rotation of the phenomenon of jamming, shaking.
The motor runs with abnormal noise and unstable speed.
Solution
Check whether the connection line of the motor drive module is loose, broken or short-circuited, re-plug and fix the connection plug, repair or replace the damaged line.
Check whether the motor driver chip is overheated or burnt, if there is any problem, replace the driver chip in time. At the same time, check whether the cooling fan is working properly to ensure that the drive module heat dissipation is good.
Check whether the motor drive parameters are set correctly, such as current limit, speed ratio and other parameters, according to motor specifications and equipment requirements to readjust the parameters.
3、Signal transmission failure
Failure phenomenon
The instruction from the operation panel cannot be accurately transmitted to the control unit, such as pressing the start button, the equipment does not respond.
The status information fed back from the control unit to the operation panel is inaccurate or incomplete, resulting in abnormal display.
Solution
Check the communication lines, including data lines, control lines, etc., to see if there are problems such as damage, breakage, poor contact, etc., and repair or replace the damaged lines.
Check the communication interfaces, such as USB interface, serial port, etc., to see if there is any looseness, oxidization, etc., clean the interface and make sure the connection is firm. If the interface is damaged, the interface needs to be replaced.
Check whether the communication protocol settings are consistent, to ensure that the communication protocol between the control unit and the operating panel, sensors and other devices match, if there is any error, reset the communication protocol parameters.
4、Program failure
Fault phenomenon
Abnormal action of the equipment, such as the slot machine paper feed, paper pressure and other actions in the wrong order.
When the equipment runs to a particular step, it crashes or reports an error.
Solution
Try to reset the controller to see if normal operation can be resumed.
If the reset is not effective, check whether there are bugs or errors in the program, and contact the device manufacturer to obtain a new program version for updating and upgrading.
Check whether the controller's memory chip is normal, whether there is data loss or damage, if necessary, replace the memory chip and rewrite the program.
5、Temperature sensor and overheating protection failure
Failure phenomenon
The temperature sensor shows abnormally high or low temperature, which does not match the actual temperature.
The device triggers overheating protection before reaching the upper limit of the normal operating temperature, resulting in shutdown.
Solution
Check whether the probe of the temperature sensor is damaged or aged, if so, replace the temperature sensor.
Check whether the installation position of the temperature sensor is correct and whether it is in good contact with the heating element to ensure that the temperature can be measured accurately.
Check whether the overheating protection threshold is set reasonably, whether the threshold is too low due to misoperation or other reasons, and reset the overheating protection threshold according to the actual situation of the equipment.
