What are the techniques that can not be ignored in the debugging of automatic winding machine?

1. Overvoltage alarm of spindle frequency converter of winding machine.

The spindle frequency converter of the winding machine produces an oL overvoltage alarm on the operation panel every time it is parked. The input power supply voltage is measured by the multimeter and found to be normal, so the problem is locked in the deceleration time set by the frequency converter. In order to reduce the inertia of the spindle parking as much as possible, the deceleration time of the frequency converter is set to be very small, which leads to a rapid decrease in the frequency of the frequency converter and a rapid decrease in the synchronous speed of the same motor after the parking signal is announced. because there is a large inertia in the winding motor, the actual speed of the winding motor exceeds the synchronous speed at this time, and the winding motor works in the generator condition, so that the frequency converter has overvoltage alarm. Through practical debugging, the deceleration time is set to 0.5s, which can not only reduce the inertia of the winding machine during deceleration, but also ensure that there is no overvoltage alarm.

2. Alarm processing of Wire arrangement Servo driver of Winding Machine.

In the process of debugging, the active wiring servo driver of the winding machine often presents a fault alarm, which is generally due to the abnormal communication between the encoder and the servo driver. after the servo driver is powered off, the CN2 of the connection plug between the encoder and the servo driver is re-plugged, and the fault is exempted after being powered on again.

3. Setting of Servo follower ability of Winding Machine.

The follower ability of the wiring servo is set through the parameters of the servo driver. the larger the parameter value is, the smaller the fault of performing the azimuth instruction is, and the stronger the follower ability is; but if this value is assumed to be too large, it is easy to cause the oscillation of the active winding machine. therefore, the setting of this parameter value should take into account the tracking of the winding machine and the other position instruction.

4. Recognition of sampling period for Wire arrangement of Winding Machine.

Suppose that during debugging, it is found that the wiring arrangement of the winding machine will show a significant phenomenon of going and stopping, and in each walking and stopping cycle, the walking time is very short and the stopping time is very long, which leads to the inconsistency of the strict density of the winding machine. You can consider reducing the sampling period to twice the PLC scan cycle and continue debugging. It is found that the wiring arrangement can move smoothly without the phenomenon of walking and stopping, and the wiring arrangement is more rigorous.

5. Tension when winding round wire.

When winding, the tension of the round wire is adjusted by the number of coils wound on the relaxing roll. when winding a relatively thin round wire, it is assumed that the adjustment of the tension value is not suitable for the situation that the thin wire will be elongated and thinned and the insulation paint will fall. Therefore, the manufacturer should sum up the appropriate number of winding coils according to different round wire diameters.

6. Tension when winding flat wire.

The tension conditioning of the winding machine when winding the flat wire is achieved by adjusting the air pressure of the disc brake pads, and we should also summarize the corresponding air pressure for different linewidths.
