Steps for frequency conversion control debugging of inverted wire drawing machine

Oct 07, 2020

The inverted wire drawing machine requires reasonable debugging during operation to ensure that the wire drawing operation can be completed smoothly. After using the inverter, in the process of debugging, the first thing is to determine the given reference voltage. The given speed voltage is taken out from a terminal, and the required full amplitude value is +10 volts, but in fact its output reaches +15 volts, so it needs to be divided.

Therefore, in the process of debugging the inverted wire drawing machine, after the inverter is powered on, it is also necessary to set its related parameters. When setting process parameters, attention should be paid to selecting different entry levels. Then determine the direction of rotation. Generally, after parameter setting, the electronic control system can work normally.

The next step is to auto-tune. In other words, before the inverted wire drawing machine runs, the main motor and the take-up motor need to be automatically tuned once. This is mainly for the convenience of the inverter to automatically obtain the relevant parameters of the motor in order to obtain the best match. When tuning, the motor should be in no-load state. With the operation of the motor, the display screen should also display the dynamic value of the output frequency and output current in a timely manner.

After about 120 seconds, the tuning is complete. In addition, drawing adjustments are also required. That is, during the on-load drawing process, the debugging work should focus on the speed matching of the take-up machine and the main machine of the inverted drawing machine. When debugging, first start at a low speed, and then gradually accelerate until the whole machine is debugged, it can be put into operation.

After using the frequency conversion system, the inverted wire drawing machine can obviously save energy during the drawing operation, and the speed adjustment is more convenient and flexible, and it can be started at a low speed. At the same time, the whole machine runs more stable and reliable. Of course, in practical applications, it is necessary to select a suitable frequency converter according to the requirements of the system. The inverter has powerful functions and abundant parameters, which helps to improve product quality.
