What are the common problems in the commissioning of motor winding machine?

The spindle inverter of the motor winding machine caused an oL overvoltage alarm on the operation panel every time it stopped, and a multimeter was used to measure the power supply voltage on the keying side, and everything was found to be normal. In order to minimize the inertia force when the spindle is stopped, the deceleration time of the inverter is set to a small amount, which causes the frequency of the inverter to decrease rapidly after the signal of stopping data is sent out, and at the same time, the same speed of the motor also decreases rapidly, because there is a large inertia force in the unwinding motor, which causes the specific speed of the unwinding motor to exceed the same speed at this time, and the unwinding motor operates in the case of the generator set. A large operating voltage is induced on the rotor side of the motor, which causes the inverter to generate an overvoltage alarm.
In the adjustment process, the motor winding machine fully automatic line row servo drive often common fault alarm, the reason is generally the servo motor and servo drive communication anomaly, the servo drive off the power, the servo motor and servo drive coupling power plug CN2 again unplugged once, again after the power, the common fault eliminated. According to the main parameters of the servo driver to set the line servo motor to follow the work capacity, the greater the value of the variable set, the smaller the deviation of the implementation of the part order, the stronger the ability to follow the work; but this value is very easy to set a large automatic winding machine vibration, so the value of this variable should be set both winding machine and the tracking of the part order.

If in the adjustment found that the line organization of the winding machine will occur a significant walking a stop condition, and in each walking stop cycle time, walking time is very short, stopping time is longer, resulting in inconsistent line tightness. We were able to consider reducing the sampling cycle time to two times the PLC scanner cycle time and adjusting it again, and found that the wire rows could be moved smoothly and were not prone to the one-walk-stop condition, and the wire rows were closer. When winding round wire tension is adjusted by the number of winding turns on the stretch roller, when winding a relatively thin round wire, if the tension value is not adjusted properly will appear thin wire is stretched thin, insulation paint off the situation, so the manufacturer should summarize the appropriate number of winding turns for different round wire diameter. When winding flat wire, the tension is adjusted by adjusting the air pressure of the disc brake pads, so we should also summarize the corresponding air pressure for different wire widths.
