BEST MODE FOR CARRYING OUT THE INVENTION A computer controller according to the present invention will be described below by taking a three-phase inverter device (three-phase inverter power supply device) as an example. FIG. 1 shows the configuration of a three-phase inverter device according to the first embodiment of the present invention. As shown in the figure, the three-phase inverter device 11 includes a microcomputer 12, a non-volatile storage unit 13, a display / operation panel 14, and an inverter circuit 15, and controls an electric motor 21 that is a control target device.

The microcomputer 12 is provided with a so-called one-chip microcomputer, and is backed up by a battery.
An internal memory 121 for storing values of operation parameters (control parameters) is provided. The internal memory 121 stores operating parameters set by the user (for example, current values of parameters that specify the rotation direction of the electric motor 21, the frequency of the AC voltage applied to the electric motor 21, the output current, the rotation speed of the electric motor 21, the output voltage, etc.). Are stored as illustrated in FIG.

The non-volatile storage unit 13 is composed of a flash memory or the like, and the three-phase inverter device 11 sets the default values and the initial values of the operation parameters, for example, as shown in FIG.
It is stored as shown in (b). Here, the default value is a set of standard values common to a plurality of users, which were set when the three-phase inverter device 11 was shipped from the factory. On the other hand, the initial value is a standard operation parameter value set by the user himself after the three-phase inverter device 11 is delivered to the user.

As shown in FIG. 3, the display / operation panel 14 includes a display section 141 and a key input section 142, and supplies commands or data corresponding to the operation of the key input section 142 to the microcomputer 12, Various information is displayed on the display unit 141 according to instructions from the computer 12.

The display unit 141 is composed of, for example, a 7-segment monitor and an LED for mode display, and can display a relatively small amount of information.

The key input section 142 includes a drive key K1, a stop key K2, a display switching / clear key K3,
Up step key (↑) K4, Down step key (↓) K
5, a program key K6, an enter key K7, and a numeric key K8 are included.

The drive key K1 is a key for instructing to start the operation of the electric motor 21. The stop key K2 is a key for instructing to stop the operation of the electric motor 21. Display switching /
The clear key K3 switches the display contents of the display unit 141 in the status display mode, and erases the input numerical data or invalidates the immediately preceding key operation in the function code display mode. The upper step key (↑) K4 and the lower step key (↓) K5 are used to switch display items.

The program key K6 switches between the status display mode and the function code display mode. Here, the state display mode is a mode for displaying the operating state of the electric motor 21, and the function code display mode is a mode for setting or confirming various parameters of the three-phase inverter device 11. .

The enter key K7 fixes the numerical data displayed on the display unit 141 and supplies it to the microcomputer 12. The numeric key K8 is provided with a numeric keypad, a decimal point key, etc., and inputs numeric data.

Referring again to FIG. 1, the inverter circuit 1
Reference numeral 5 denotes a semiconductor switch group such as a transistor and a thyristor, which is turned on by the microcomputer 12.
A switching operation is performed by the off control signal to supply electric power to the electric motor 21, which is a device to be controlled. The rotation speed, torque, etc. of the electric motor 21 are controlled by the voltage, current, frequency, etc. of the power supplied by the inverter circuit 15. That is, the microcomputer 12 uses the inverter circuit 15 (or in cooperation with each other) to control the electric motor 21 that is the device to be controlled.
To control.

Next, the three-phase inverter device 11 having the above structure
The operation of will be described. First, this three-phase inverter device 11
When shipped from the factory, only the default operation parameters shown in FIG. 2B are set in the non-volatile storage unit 13, and the user-set initial value is in the unregistered state.

After the three-phase inverter device 11 is carried in to each user, each user operates according to the type and drive content of the device to be controlled (the electric motor 21 in FIG. 1) and the operation parameters appropriate for that user. Set in the non-volatile storage unit 13.

For this processing, the operator switches the operation mode of the display / operation panel 14 to the function code display mode with the program key K6. Next, a predetermined code number designating "setting of initial value of operation parameter" is input by the numerical key K8, and the enter key K7 is pressed.

In response to this pressing operation, the microcomputer 12 starts the control operation shown in the flowchart of FIG. First, the operator inputs the number of the setting target parameter (parameter number) using the numerical key K8 (step S101). The microcomputer 12 displays the input parameter number (step S102).

When setting the parameter value (parameter value) of the displayed number, the operator presses the enter key K7, and then inputs an arbitrary value with the numerical key K8. The microcomputer 12 detects the pressing operation of the enter key K7 (step S103; Y).
ES), the value registered at that time (for example, "00
00 "or" FFFF ") is displayed (step S10).
4). Further, the input numerical value is accepted (step S105; YES) and displayed (step S106).
If the displayed value is OK, the operator can enter key K
Press 7. The microcomputer 12 responds to the operation of the enter key K7 (YES in step S107).
S), and stores the input parameter value in the corresponding area of the non-volatile storage unit 13 (step S108). To change the numerical value once input, for example, the clear key K3 is operated.

When switching the operation parameter, the operator again inputs the parameter number by the numerical key K8 (step S108). Microcomputer 1
2 displays the input parameter number (step S109). When setting the parameter value of the displayed parameter number, the operator presses the enter key K7 to set the numerical value as described above (steps S103 to S108).

In this way, the operator registers an initial value convenient for himself, in addition to the default value.

Note that it is difficult to manually set the initial values of all the operating parameters. Therefore, you can edit the default value and set the initial value. In this case, the operator presses the program key K6 to display / operate the panel 14
Switch the operation mode of to the function code display mode. Next, a predetermined code number designating "write a default value as an initial value" is input with the numerical key K8, and the enter key K7 is pressed. In response to this pressing operation, the microcomputer 12 executes a process (copy process) of writing a default value as an initial setting value. After that, the setting process shown in the flowchart of FIG. 4 is performed to correct only the operation parameters that need to be corrected. In this way, normally, the initial value setting process becomes easy.

This completes the initial value setting process.

Next, in order to actually operate and control the electric motor 21, the value of the operation parameter (currently
Operation parameter value) . For this setting process, the operator switches the operation mode of the display / operation panel 14 to the function code display mode with the program key K6. Next, a predetermined code number designating "batch rewriting of operation parameters" is input by the numerical key K8, and the enter key K7 is pressed.

In response to this key operation, the microcomputer 12 performs a predetermined batch rewriting process shown in FIG. First, when a parameter number for batch rewriting is input to the microcomputer 12 using the numerical key K8, data "0" is displayed on the display unit 141 (step S201).

When the user wants to copy the initial value set in the non-volatile storage unit 13 to the internal memory 121, the user inputs the value "1" with the numeric key K8 and registers it in the non-volatile storage unit 13. The default value that has been set is the internal memory 1
If the user wants to make a copy in 21, the value "2" is input with the numerical key K8, and then the enter key K7 is pressed. The microcomputer 12 determines the input value (steps S202 and S203), and when the value is determined to be “1”, sequentially reads the initial value from the non-volatile storage unit 13 and stores it in the internal memory 121. Write (step S20
4) On the other hand, when it is determined that the input value is “2”, the default value is sequentially read from the nonvolatile storage unit 13 and written in the internal memory 121 (step S2).
05).

Then, the microcomputer 12 executes the editing process of the operation parameters stored in the internal memory 121 (step S206). The content of this process is
Except that the access target is the internal memory 121,
The process is substantially the same as the process shown in the flowchart of FIG. 4, and the operator individually sets the operation parameter appropriately by key operation according to the object to be controlled.

After the setting of the internal memory 121 is completed, the operator presses the drive key K1 to drive the electric motor 21. The microcomputer 12 has a drive key K
In response to the pressing operation of 1, according to the operation parameter (current parameter value) stored in the internal memory 121,
The electric motor 21 is started via the inverter circuit 15 (the electric motor 21 is started by controlling the electric power output from the inverter circuit 15), and is stopped in response to the pressing operation of the stop key K2.

There are cases where it becomes necessary to reset the operating parameters of the three-phase inverter device 11 due to various reasons such as the replacement of the electric motor 21 and the replacement of the object to be driven. In this case, when the number of operation parameters to be corrected is small, the operator individually specifies the operation parameter and corrects the value. This operation is substantially the same as the processing shown in FIG. 4 except that the storage device to be processed is the nonvolatile storage unit 13 or the internal memory 121.

On the other hand, when there are many correction points, especially when it is not clear which parameters have been corrected and which have not been corrected after the operation parameters have been corrected several times, It may be easier to correct the contents of the internal memory 121 once restored to the initial value or the default value and then corrected. In this case, the operator selects one of the initial value and the default value stored in the non-volatile storage unit 13 by the process of FIG. 5 (steps S202 and S203) and sets the contents of the internal memory 121 to the initial value. Or, restore the default value (steps S204, S
205), and subsequently, some operation parameters are individually corrected (edited) (step S206).

Since the initial value registered in the non-volatile storage unit 13 stores a set of parameter values that is common to this user, the amount of correction is small and the correction is relatively easy in many cases. Further, in the case of controlling a completely different object from the conventional one, it is possible to suppress the correction amount by selecting a default value, expanding it in the internal memory 121, and correcting this. Therefore, the operation parameters can be corrected (edited) efficiently.

In the above embodiment, the initial values stored in the non-volatile storage unit 13 are one set (one set), but depending on the system, a plurality of initial values may be set as shown in FIG. You may allow it. Further, each set of initial values may be combined with the device to be controlled. In this case, for example, as shown in the flowchart of FIG. 7, when the number of the set of initial values is designated according to the type of the control target device (step 302, S
303), a set of initial values or default values corresponding to the designated numbers (0 to n) may be set in the internal memory 121. According to this method, since the set of initial values suitable for the controlled device is set in the internal memory 121, the correction amount can be further reduced.

Furthermore, if an index is provided and the model of the control target device is designated, the corresponding initial value number is selected by the index, and the set of the initial value is expanded in the internal memory 121. Good.

The present invention is not limited to the above embodiment, and various modifications and applications are possible. For example, in the above-described embodiment, the comparatively small seven segment system is used as the display unit 141, but it is also possible to use a display element such as a liquid crystal display panel.

Further, it is not necessary to store the default value and the initial value of the operation parameter in the non-volatile storage section 13. For example, every time the parameter value is compared with the default value, a predetermined process is performed to perform a micro process. Computer 12
May be generated. Further, it is not necessary to store the default value and the initial value in the non-volatile storage unit 13, and they may be stored in the backed up internal memory 121. Alternatively, the non-volatile storage unit 13 may be composed of a removable flash memory or the like and mounted in a slot of a personal computer so that the initial value can be set or changed on the computer. With this configuration, setting / updating of the initial value becomes easier.

The hardware configuration disclosed in FIGS. 1 and 3, the memory map shown in FIGS. 2 and 6, and FIGS.
The processing procedure and the like shown in FIG. 7 can be arbitrarily changed. Further, in the above description, the embodiment in which the electric motor is controlled by the three-phase inverter device that operates according to the operation parameter has been described, but the control target is arbitrary, and the operation parameter obtained by changing various electric / electronic devices from the default values. It is widely applicable to control devices that can be controlled by using.

A program for operating the computer as all or part of the above-mentioned control device or executing the above-mentioned setting processing is stored in a computer-readable recording medium such as a CD-ROM or MO. Alternatively, the program may be distributed, installed in a computer, operated as the above-mentioned means, or the above-mentioned steps may be executed.
