Embodiment
Below in conjunction with accompanying drawing, describe particular content of the present utility model in detail for example:
The commissioning device of air-jet loom special converter as shown in Figure 1, comprise control code drive plate 1, frequency converter 3 to be measured, alternating current generator 2, current sensor 4, amplifier 5, oscillograph 6, wherein, the output terminal of control code drive plate 1 is connected with the input end of frequency converter 3 to be measured, and the output terminal of frequency converter 3 to be measured is connected with alternating current generator 2, current sensor 4 is connected with the output terminal of frequency converter 3 to be measured, by amplifier 5, the output AC signal shows on oscillograph 6, below its principle and circuit is described:
At first the signal output interface of control code drive plate 1 and frequency converter to be measured are connected, this control code drive plate 1 is output as eight control codes, the ac output end of next frequency converter connects the AC three-phase asynchronous motor 2 of coupling, adds the alternating voltage of 200V50HZ again to frequency converter.
Because what adopt is that pressures/frequency mode is controlled motor, what is called pressure/frequency mode is that the amplitude of the three-phase alternating voltage exported of frequency converter is corresponding with certain frequency---the corresponding unique magnitude of voltage of Frequency point.So can obtain an electric voltage frequency corresponding tables accurately according to this characteristic, use the knowledge of mathematical statistics to summarize the relation of frequency values and frequency converter input control signal by repeatedly experiment measuring again.Now use the control code of a group octet to replace the upper input signal of frequency converter, can obtain the accurate corresponding tables of a frequency values and eight control codes by the relation of top frequency values and frequency converter input control signal.And then can controlled sign indicating number, frequency, magnitude of voltage three's corresponding relation.
The following describes and how to carry out the Frequency point test: when requiring to test the duty of a certain Frequency point low-converter, the corresponding unique control code of Frequency point therewith that only needing to table look-up obtains configures on this novel debugger, use the output end voltage of the interchange shelves Measurement for Inverter of multimeter again, and this measured value and frequency control code table contrasted, check whether two values meet to get final product.
Shown in Figure 2 is the circuit theory diagrams of control code drive plate 1, and wherein D1-D10 is a pilot lamp, when it lights the interval scale control code position (or enable signal) corresponding with it effectively.S2 is two enable signals among the figure, when they all effectively the time, eight control codes exporting to frequency converter controller just can be received and produce corresponding three-phase alternating voltage at inverter output terminal.
