What are the techniques that cannot be ignored in the commissioning of automatic winding machine?

1, alarm przepięcia falownika wrzeciona maszyny nawijającej

The spindle inverter of the winding machine produces an oL overvoltage alarm on the operation panel every time it is parked, and the input side power supply voltage is measured with a multimeter and found to be normal, so the problem is locked in the deceleration time set by the inverter. In order to minimize the inertia of the spindle when parking, so the deceleration time of the inverter is set very small, resulting in the frequency of the inverter dropping quickly after the parking signal is announced, and the synchronous speed of the motor also drops quickly, because there is a large inertia of the winding motor, making the actual speed of the winding motor exceed the synchronous speed at this time, and the winding motor works in the generator condition, so that the inverter over-voltage alarm occurs. Through practical debugging, the system sets the deceleration time to 0.5S, which can not only minimize the inertia of the winding machine deceleration, but also ensure that no over-voltage alarm occurs.

2. Alarm handling of the winding machine lineup servo driver

In the commissioning process, the winding machine active line servo driver often presents a fault alarm, the reason is generally the encoder and servo driver communication failure, the servo driver power off, the encoder and servo driver connection plug CN2 re-plug once, again after the power, the problem is eliminated.

3. Winding machine lineup servo follow the ability to set

The larger the value of the parameter, the smaller the fault in the implementation of the orientation instruction, the stronger the ability to follow; but the value is assumed to be set too large to cause active winding machine oscillation, so the value of the parameter should be set to take into account the winding machine and the tracking of the orientation instruction.

4. The recognition of the sampling period of the winding machine lineup

Assuming that during debugging, it is found that the arrangement of the winding machine will show a significant phenomenon of a walk and a stop, and in each walk-stop cycle, the walk time is very short and the stop time is very long, resulting in inconsistent density of the line. Can consider reducing the sampling period to twice the PLC scan period, continue debugging, found that the line arrangement can move very smoothly, will not present a go a stop phenomenon, the line is also more tight.

5. Tension when winding round wire

When winding the tension of the round wire is adjusted by the number of winding turns on the stretch rollers, when winding a relatively thin round wire, assuming that the tension value adjustment is not suitable for the thin wire will be stretched thin, insulating paint fall, so the manufacturer should summarize the number of suitable winding turns for different round wire diameter.

6. tension when winding flat wire

The tension adjustment of the winding machine when winding flat wire is achieved by adjusting the air pressure of the disc brake pad, we should also summarize the corresponding air pressure size for different wire widths.
