What are the common control unit failures and solutions for motor motor rotor 4-station double flying fork winding machine?
The control unit of motor motor rotor four-station double flying fork winding machine may have the following common faults and their solutions:
1、 electromagnetic interference caused by failure:
Failure phenomenon: frequent shutdown, set parameters are not saved or confused.
Solution: Give the winding machine a separate power supply or add capacitors to reduce the impact of electromagnetic interference.
2、Faults caused by fluctuations in the power grid:
Failure phenomenon: controller no output signal, inverter over-voltage or under-voltage alarm.
Solution: Add an AC voltage regulator to the power input of the winding machine to stabilize the grid voltage.
3、Failure caused by abnormal external signal input:
Solution: Check whether the signal input is correct, and make sure all the input signals meet the requirements of the equipment.
4、Mechanical system failure:
Failure phenomenon: temperature rise, strong vibration, noise.
Solution: Check the operation of the spindle and line system to ensure that the lubrication is in place, no displacement of parts, the pitch is set reasonably, the screws are tight, no damage to parts.
5、Electrical system failure:
Solution: Starting from the signal input, step by step troubleshooting, check whether the electrical components are associated, to find out the point of failure.
6、Reset method for the whole machine:
Solution: For transient faults caused by the entire machine error, you can reset the hardware or switch the system power supply in turn to clear the fundamental faults.
7、Compile test run program:
Solution: Compile a reasonable program and run successfully, check and correct user program errors to ensure that the system operates normally.
8、Make full use of adjustable components adjustment:
Solution: Adjust the winding tension, shielding voltage and the starting position of the cable rack, etc. to correct some harmless faults.
9、Check the control system:
Solution: Check whether the control system such as PLC and touch screen work properly, including input and output signals, program operation status, etc..
10、Fault code and alarm:
Solution: Check whether the machine has a fault code or alarm information, this information can provide the specific location and cause of the fault, according to the prompts for the appropriate maintenance.
The above is based on the search results summarized four-station double flying fork winding machine control unit common faults and their solutions. In actual operation, fault diagnosis and treatment should be carried out according to the specific situation.
Case:
Fault case: tensioner failure
Failure phenomenon: in the four-station double flying fork winding machine operation process, the tensioner overheating or burned, resulting in tension control failure.
Possible causes: Tensioner failure may be due to high or low supply voltage, high operating frequency, poorly manufactured coils or due to mechanical damage, insulation damage and other reasons.
Solution:
Adjust the supply voltage: Check and adjust the supply voltage to make sure it is within the specified operating range of the unit.
Replace the coil or contactor: If the coil or contactor is damaged, it needs to be replaced with a new one.
Select other suitable contactors: According to the requirements of the equipment and working conditions, select more suitable contactors to avoid overheating or burnout.
Rectify mechanical damage: Check the mechanical parts of the tensioner to eliminate possible mechanical damage and ensure that the tensioner can work normally.
Through the above steps, you can effectively solve the faults of the control unit of the tensioner of the four-station double flying fork winding machine, and ensure the normal operation and production efficiency of the winding machine.
