For example, in the case of an inverter that is a driving device of a three-phase induction motor, it is necessary to set various control parameters such as a driving frequency, an exciting current, and a rated slip according to the load of the motor and characteristics of the driving method. By appropriately setting the values of these control parameters (hereinafter, sometimes simply referred to as parameters), it is possible to obtain the maximum efficiency with a small motor. Further, adverse effects on the mechanical system and surroundings can be reduced.

FIG. 1 is a front view showing an example of an inverter which is a motor driving device. The inverter 50 is mounted on, for example, a DIN rail in the control panel. At the lower part of the inverter 50, a terminal block 51 to which an electric cable connected to a three-phase induction motor to be controlled or the like is connected is provided. At the top, a bar graph LED 52 for displaying the state of the load (motor), an exemplary current, and the like, and a 4-digit 7-segment LED 53 for numerically displaying information such as the operating state and parameter setting values are provided.

Below the four-digit seven-segment LED 53, there are provided a plurality of push-button switches 54 for instructing start and stop of the motor and setting parameters, and on the right thereof are used for setting parameters. A dial 55 is provided. The user of the inverter 50 uses the push button switch 54 and the dial 55 to set the above control parameters.

Below the push button switch 54, there is provided a modular jack 56 for connecting a communication cable for communicating with an external device. For example, the inverter 50
By connecting a personal computer to the personal computer, control parameters can be set by the personal computer. If the parameters are set using the display device, keyboard, mouse, etc. of the personal computer, the limited push button switch 54 of the inverter 50 as described above
The setting operation can be performed more easily than in the case where the setting is performed using the dial 55, the dial 55, and the 4-digit 7-segment LED53.

[0006] Special application software for setting parameters operating on such a personal computer has also been developed. According to this dedicated application software, a list of codes (numbers), names, set values (initial values), maximum values, minimum values, etc. of each parameter is displayed using a display device of a personal computer, and scrolling of the screen and Select the parameter setting field to be changed by mouse operation, and change the setting value by inputting from the keyboard. Then, the data including the set values of the changed parameters is collectively transferred from the personal computer to the inverter.

FIG. 9 is a flowchart showing an outline of the processing performed by the processing unit 15 for displaying the dialog boxes 21 to 25 shown in FIGS. 3 to 7 and extracting parameters to be changed.

In step # 101, a use selection dialog box (21 in FIG. 3) is displayed.
In 02, the user selects a use. In the processing after step # 103, the display of the question dialog, the input of the answer by the user, and the processing of obtaining the parameter to be changed and the recommended value by referring to the above table according to the answer input are repeated.

First, a question dialog box is displayed in step # 103. As shown in dialog boxes 22 and 25 shown in FIGS. 4 and 7, when a plurality of options are prepared as answers (Yes in step # 104)
s), those options are displayed (step # 10)
5) The user performs a selection input (step # 106).

As shown in the dialog boxes 23 and 24 shown in FIGS. 5 and 6, when an option is not prepared and a numerical value input is required (No in Step # 104), a numerical value input field is displayed (Step #). 107). Step # 10
When the user inputs a numerical value as described above in step 8, the processing device 15 determines which of the previously divided areas is included in the input numerical value (step # 10).
9). That is, by dividing the inputtable numerical value range into a plurality of appropriate regions in advance, it is possible to perform the same processing as the above plurality of options. For example, 0-1
The frequency range of 00 kHz may be divided into five regions of 20 kHz each. However, it is not always necessary to divide equally, and an appropriate division may be performed according to the item.

Thereafter, the processing device 15 proceeds to step # 110.
In step (1), parameters to be changed and set according to the user's answer input (according to the selected option or the area to which the input numerical value belongs) and their recommended values are obtained with reference to the table. Steps # 103 to # 110 are repeated until all questions are completed (step # 111). When all questions are completed, the completion dialog box 26 shown in FIG. 8 is displayed as described above.

Although omitted in FIG. 9, step # 10
It is also possible to use the numerical value input in 8 as it is as the parameter recommended value. In this case, step # 109
Is omitted. For example, when the rated frequency and the rated voltage are set as parameters in the motor driving device 50, the numerical values of the rated frequency and the rated voltage input in the question dialog 23 of FIG. 5 can be directly used as the recommended values.

It is not necessary to limit the number of question items displayed in one question dialog box to one. As in the question dialog box 22 of FIG. 4, a plurality of related question items may be displayed at a time. In this case, the user can answer a plurality of question items in an arbitrary order.
Then, the communication device 14 can obtain a recommended value of one parameter from the matrix according to the plurality of input answers.

In the flowchart shown in FIG. 9, every time one question dialog box is displayed, the processing unit 15 obtains parameters to be changed and their recommended values according to the input answer. However, another processing method may be adopted. That is, when questions and answers in a plurality of question dialog boxes are completed, parameters to be changed and their recommended values may be obtained. Alternatively, when the questions and answers in all the question dialog boxes are completed, a plurality of parameters to be changed and their recommended values may be obtained collectively.

FIGS. 10 and 11 show another example of a method for setting the control parameters of the motor driving device 50 by the parameter setting support device 10 of the present embodiment. FIG. 10 (a)
In (e), the square frame on the left side is a simplified drawing of a dialog box displayed on the display device 11. On the right side, the number and value (recommended value) of the control parameter determined by the processing device 15 according to the question item and the answer in each dialog box are shown. The selection input in each dialog box, the operation for proceeding to the next dialog box, and the like are the same as in the above-described example.

Assuming that a fan (fan) is selected in the application selection dialog box 31 of FIG. 10A, as shown in a block 32, three control parameters (P2_00, P2_10, P2_30) and their values (1) , 2, 1) are extracted from the aforementioned table. Control parameter number (number starting with P in parentheses)
Represents the group number and the item number in the group, but is merely an example.

In the next question dialog box 33 shown in FIG. 10B, a question item concerning the capacity of the motor to be used is displayed, and an answer by selection input is required. Further, in a question dialog box 34 shown in FIG. 10C, a question item regarding the diameter of the blower blade is displayed.
In this case also, an answer by selection input is required. According to the answers of these two question items, a recommended value of one parameter (P1_20) is obtained from the matrix 36 as shown in a block 35.

That is, the fourth option is selected in the question dialog box 33 and the question dialog box 34 is selected.
In response to the selection of the second option in step (4), the element (0) in the fourth column and second row of the two-dimensional matrix 36 is obtained as the recommended value of the parameter (P1_20). Generally, in order to obtain a recommended value of one parameter (P1_20) according to answers (options) of n natural number question items, it is necessary to prepare an n-dimensional matrix.
The number of elements in each column (row) corresponds to the number of options for the question.

The question dialog box 3 shown in FIG.
In 7, a question item relating to the rising of the ventilation is displayed, and an answer by selection input is required. According to the answer, a recommended value of one parameter (P1_25) is determined as shown in block 38. In this case, the recommended value is simply obtained from the table 39 having four elements corresponding to the four options.

The question dialog box 4 shown in FIG.
In the case of 0, a question item regarding the equipment environment of the blower is displayed, and an answer by selection input is required. According to the answer, the recommended values of the two parameters (P2_60, P2_61) are obtained as shown in block 41. In the case of this question item, any number of options can be selected from a plurality of options. Then, as shown in Table 42, the default values (P2
_60 = 40, P2_61 = 20) are defined for each option.

In the example shown, the first and third options are selected from the three options. Referring to Table 42, for the first option, the parameter P2
_60 is reduced by 10 from the default value (40),
Parameter P2_61 is 10 from the default value (20).
Only increased. Further, for the third alternative, the parameter P2_60 is reduced by 10 and the parameter P2
_61 is incremented by 10. As a result, block 41
As shown in the figure, the recommended values of the two parameters (both 4
0) is required.

FIG. 11 shows an example in which a list including parameters to be changed and their recommended values is displayed by a user's instruction input when answers to all question items are completed as described above. I have. The setting parameter list table 43 displays parameter names and remarks, along with parameter numbers and setting values (recommended values). In the remarks column, cautionary notes and the like that are helpful when changing the numerical value in the setting value column by direct input are displayed.

In the above embodiment, a method of displaying a question item and a method of inputting its answer (selection input, numerical value input),
The method of obtaining the control parameters from the answer input and the configuration of the table used at that time have been described with some examples. Note that the number of question items (or the number of pages displaying question items) changes according to the use of the electric motor. The number of question items or the number of question pages may be included in the data table for each application.

Parameter setting method of the present invention (supporting device)
The present invention is not limited to the above embodiment, and can be implemented in various forms. Some other embodiments are listed below.

In the display of the setting parameter list shown in FIG. 11, in order to support direct setting by numerical input of each parameter, a more detailed description or illustration than the description in the remarks column may be displayed. For example, a description or illustration (that is, a help display) of the parameter selected in the setting parameter list or the row in which the cursor is located
Can be displayed. The help display as described above may be added in a mode in which not only the parameter list to be changed as shown in FIG. 11 but also a parameter list including parameters not to be changed is displayed.

After a use selection input is made in the use selection dialog box shown in FIG. 3 or FIG. 10 (a), a default characteristic graph is displayed together with the question dialog box, and the characteristic graph is displayed according to the answer input to the question. Changes may be displayed by simulation. For example, a characteristic graph indicating the relationship between the rotation speed of the electric motor and time can be displayed in real time by simulation. The user may select an answer option so that the characteristic graph approaches an ideal curve.

A plurality of curves may be displayed as a characteristic graph instead of, or together with, a question in writing, and the user may select an ideal curve from among them to give an answer.
