What are the common control unit malfunctions and solutions for motor motor automatic rotor fine turning vision machine?
The control unit of the motor motor automatic rotor fine turning vision integrated machine is responsible for coordinating the operation of all parts of the equipment, and any failure will seriously affect the production. The following are common failures and solutions:
1、Control command transmission abnormality
Failure phenomenon: After the operator interface commands, the equipment's actuators (such as spindle motors, feed system, etc.) no response or response delay, and the control unit has no obvious error message.
Cause analysis: the communication line between the control unit and the actuator has a broken circuit, short circuit or poor contact. For example, in the long-term operation of the equipment, frequent vibration may lead to loose terminals; control unit of the communication interface chip is damaged, possibly due to electrostatic shock, overvoltage, etc.; control program responsible for the transmission of instructions in the part of the logic error, resulting in instructions can not be correctly packaged and sent.
Solution: Use a multimeter to test the communication line section by section, repair the breaks and shorts, and re-tighten the terminals. If the line is normal, need to replace the communication interface chip of the control unit, and at the same time do a good job of electrostatic protection and over-voltage protection measures; software engineers on the control program for all the troubleshooting, focusing on checking the instruction transmission module, fix the logical errors, recompile and download the program if necessary.
2、Parameter setting confusion
Failure phenomenon: equipment processing precision decline, such as turning the rotor size deviation is too large, or abnormal action during processing. Inspection found in the control unit preset processing parameters, such as speed, feed, depth of cut, etc., change for no reason.
Reason analysis: the control unit's memory chip failure, resulting in unstable parameter storage, data easily lost or messed up; operator misoperation, unknowingly modified the key parameters; software by the virus or malicious program attack, tampering with the parameter settings.
Solution: Replace the storage chip of the control unit to ensure that the parameters can be stored stably. At the same time, increase the parameter backup and recovery function in the control program, and back up the parameters regularly; strengthen the training of operators, standardize the operation process, and set the operation authority to prevent misoperation. Install professional anti-virus software and firewalls to check and kill all operating systems of the control unit, clear out viruses and malicious programs, and restore the correct parameter settings.
3、Control unit crash or restart
Failure phenomenon: During the operation of the equipment, the control unit suddenly stops responding, the operating interface freezes, or automatically restarts, resulting in processing interruptions, affecting the production schedule.
Cause analysis: control unit hardware heat dissipation is poor, after a long period of high load operation, the chip overheating triggers the protection mechanism. For example, faulty cooling fan, serious accumulation of dust on the heat sink; failure of the power supply module, unstable output voltage, resulting in abnormal operation of the control unit; the control software has memory leakage, resource conflict and other problems, and the system resources are exhausted after a long time of operation.
Solution: Clean the dust on the cooling fan and heat sink, check whether the fan is operating normally, and replace it promptly if it is faulty. Ensure that the control unit is installed in a well-ventilated environment; detect the output voltage of the power supply module, use a regulated power supply or replace the faulty power supply module; software developers to optimize the depth of the control software, repair memory leakage and resource conflict problems, regular system maintenance of the control unit, clean up the cache and temporary files, release system resources.
4, and other equipment communication failure
Failure phenomenon: motor motor automatic rotor fine turning vision machine and external equipment (such as material handling systems, quality testing equipment, etc.) can not communicate normally, data transmission interruption, resulting in abnormal cooperative work between the equipment.
Reason analysis: mismatch of communication protocols, different devices use different communication protocols, not properly converted; communication interface damage, may be due to improper plugging and unplugging, electrical corrosion, etc.; communication network congestion, a large number of data transmission at the same time, resulting in data packet loss or delay.
Solution: Check the communication protocols of each device, ensure the consistency of communication protocols by writing a communication conversion program or using a protocol converter; replace damaged communication interfaces and take protective measures for the interfaces; optimize the communication network, increase the network bandwidth, reasonably allocate the data transmission time, and reduce network congestion by adopting technologies such as data caching and asynchronous transmission.
