1, winding machine spindle inverter overvoltage alarm

Winding machine spindle inverter in each parking oL overvoltage alarm on the operation panel, using a multimeter to measure the input side of the power supply voltage, found normal, so the problem is locked in the inverter set deceleration time. 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 very quickly after the parking signal is announced, and the synchronous speed of the motor drops very 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 moment, the winding motor runs in the generator condition, so that the inverter has an overvoltage alarm. After practical debugging, the deceleration time of this system is set to 0.5S, which can minimize the inertia of the winding machine deceleration and ensure that no overvoltage alarm occurs.

2. Alarm handling of the winding machine lineup servo driver

In the commissioning process, the winding machine active lineup servo driver often fault alarm, the reason is usually the encoder and servo driver communication anomaly, the servo driver power off, the encoder and servo driver interface plug CN2 re-plug once, again on the power, the problem is eliminated.

3. Winding machine lineup servo follow the ability to set

After the servo driver parameters to set the line servo follow the ability, the greater the value of the parameter set, the smaller the error in the implementation of the directional command, the stronger the ability to follow; but this value if set too large is likely to cause active winding machine vibration, so the value of this parameter should be set to take into account the winding machine and the tracking of the directional command.

4. Winding machine line sampling period confirmation

If the commissioning found that the winding machine’s line organization will appear a significant phenomenon of a walk and a stop, and in each walk stop cycle, the walk moment is very short, the stop moment is very long, resulting in inconsistent line strict density. Can consider reducing the sampling period to twice the PLC scan period, continuous debugging, found that the line organization can move very smoothly, will not appear a walk a stop phenomenon, the line is also more tightly.

5. Tension during round wire winding

The tension of the winding round wire is adjusted by the number of winding turns on the stretch roller, when winding a relatively thin round wire, if the tension value adjustment is not suitable for the thin wire will be stretched thin, insulation paint off the situation, so the manufacturer should summarize the appropriate number of winding turns for different round wire diameter.

6. tension when winding flat wire

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