Abstract

PURPOSE:To offer a parameter setting device capable of selecting or setting the parameter of the controller of a motor, etc., in a form easy to use. CONSTITUTION:At the time of designating the parameter in a storage means 8 by a selecting means 1, a selecting range control means 8 limits automatically the output range of the selecting means 1 within only the range suitable to that control designated separately. Then, an address converting means 4 converts the output of the selecting means 1 into the address of the storage means 3 by a conversion rule suitable to that control set separately, and designates the parameter. Since an object to be selected among the many parameters existing in the storage means 3 can be narrowed to only the range suitable to that control, the selection or the setting of the parameter becomes easy to perform.

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parameter setting device for selecting and setting the operations and functions of various control devices.

0002

2. Description of the Related Art In recent years, with the rapid development of power electronics, microelectronics, etc., the applications of motors that are variable speed controlled by control devices such as servo drivers and inverters have expanded and become more diverse. As a result, these control devices are required to have many functions, and users are required to be able to easily select and set the functions they need from a wide variety of functions.

[0003] Conventionally, in response to these requirements, Japanese Patent Laid-Open No. 62
As shown in Japanese Patent No. 201081, it has been common practice to store parameters used for control in a non-volatile memory or the like to accommodate multi-functionality. The configuration will be described below with reference to FIG. 4. The parameter setting device is composed of parameter selection means 1, parameter setting means 2, parameter storage means 3, and address conversion means 4. The parameter selection means 1 consists of a rotary switch for directly specifying the type and number of the parameter, a numeric keypad from "0" to "9", or keys for specifying an increase or decrease in the contents of the parameter. The parameter setting means 2 also includes a numeric keypad, keys for instructing increase or decrease, or a variable resistor for instructing parameter contents in an analog manner. Further, the parameter storage means 3 is composed of a non-volatile memory such as an EEPROM, and its address is obtained by converting the output of the parameter selection means 1 by the address conversion means 4.

In the above configuration, the parameter selection means 1
To convert the output from the parameter storage means 3 into an address, for example, use the output of the parameter selection means 1 as is, convert it into an address by a calculation formula such as simply multiplying it by an integer, or use a conversion table. will be carried out.

[0005]

[Problem to be Solved by the Invention] However, in the above configuration, the conversion rule from the output of the parameter selection means 1 to the address of the parameter storage means 3 is fixed, and the number of parameters increases and becomes more diverse. This results in an increase in parameters that are unnecessary for certain applications.
There was a problem that it became difficult to easily select and set the necessary functions. This tendency is particularly noticeable when the parameter selection means 1 does not have a numeric keypad and parameters are selected only by key operations for incrementing or decrementing parameter numbers.

[0006] The present invention solves the above-mentioned problems, and makes it possible to rearrange the positions of parameters and to facilitate selection and setting so that frequently used and important parameters can be easily selected according to each application. It is an object of the present invention to provide a parameter setting device for a control device such as a motor, which makes it possible to limit the number of possible parameters to the necessary minimum.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a parameter storage means, a parameter selection means, a selection range limitation means for limiting the output of the parameter selection means, and a selection range limitation means for limiting the output of the selection range limitation means. a selection range storage means for specifying restriction content; a selection range selection means and a selection range setting means for updating the storage contents of the selection range storage means;
address converting means for converting the output of the selection range limiting means into an address of the parameter storing means; parameter setting means for setting the contents of the parameter storing means specified by the address converting means; and specifying a method of address conversion. a conversion rule storage means for updating the stored contents of the conversion rule storage means, a conversion rule selection means and a conversion rule setting means for updating the stored contents of the conversion rule storage means, and the selection range selection means and the selection range setting means The contents are set, and the contents of the conversion rule storage means are set by the conversion rule selection means and the conversion rule setting means.

[0008]

[Operation] With the above-described structure, the present invention can treat address conversion rules as a kind of parameter, and can arbitrarily associate the addresses of the parameter selection means and the storage means, so that Frequently used parameters can be rearranged, and the range of parameters that can be selected can be restricted using the parameter selection means, so you can easily select and set parameters by narrowing down to the minimum necessary parameters for each application. be able to.

【Example】

(Embodiment 1) An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a parameter setting device of a motor control device according to a first embodiment of the present invention. In FIG. 1, 1 is a parameter selection means, 2 is a parameter setting means, 3 is a parameter storage means, 4 is an address conversion means, 5 is a conversion rule storage means for specifying the address conversion method of the address conversion means 4, and 6 is a plurality of conversion rule selection means for specifying a specific rule from among the conversion rules;
8 is a conversion rule setting means for setting the contents of the conversion rule storage means 5 designated by the conversion rule selection means 6; 8 is a selection range limiting means for limiting the output of the parameter selection means 1; 9
10 is a selection range storage means for specifying the restriction content of the selection range restriction means 8; 10 is a selection range selection means for selecting either the upper limit or the lower limit to be restricted by the selection range restriction means 8; and 11 is the selection range selection means 10. This is selection range setting means for setting the contents of the designated selection range storage means 9. The difference from the configuration of FIG. 4 explained in the prior art section is that conversion rule storage means 5 for specifying the conversion method in address conversion means 4 is provided, and conversion rule selection means 6 and conversion rule setting means 7 are provided. A selection range restriction means 8 is provided to enable selection and setting of the contents of the conversion rule storage means 5 and to limit the output of the parameter selection means 1, and a selection range selection means 10 and a selection range setting means 11 are provided. The point is that the contents of the selection range storage means 9 can be set by using the method.

FIG. 3 is a diagram for explaining the structure and operation of the parameter storage means 3, the conversion rule storage means 5, and the selection range storage means 9. The following description takes the case where the number of parameters is five as an example. . The parameter storage means 3 is allocated to areas from addresses "0" to "4" in the nonvolatile memory 51, and five parameters are stored, one at each address. Further, the conversion rule storage means 5 is a conversion table allocated to the area from address "5" to "9", and the parameter storage means 3
The above address is stored. Further, the selection range storage means 9 is allocated to addresses "10" to "11",
As the lower limit value (smaller number) of the selection range, a value corresponding to the output of the parameter selection means 1 is stored at address "10", and the upper limit value is stored at address "11". FIG. 3(a) shows a state in which parameters are not rearranged and selection restrictions are not performed, and since the output of the parameter selection means 1 is within the selection range, the address conversion means 1 and the address conversion means 4
Then, the bias ("5" in the embodiment) of the conversion rule storage means 5 is added to the output of the selection range limiting means 8. Next, the data in the nonvolatile memory 51 is read using the result as an address. In this case, the parameters are not rearranged, and the data value is the address minus the bias, which matches the output of the parameter selection means 1. Therefore, by accessing the nonvolatile memory 51 using this data as an address, parameters can be set by the parameter setting means 2 as in the conventional example shown in FIG.

Next, a case where parameters are rearranged and selection restrictions are applied will be explained using FIG. 3(b). First, a method for rearranging parameters will be explained. for example,
Consider the case where "parameter 4" in the state of FIG. 3(a) is relocated to the position of "parameter 1". for that,
Address "4" of "parameter 4" may be set in the area for storing the address of "parameter 1" on conversion rule storage means 5 (in the embodiment, address "6" of non-volatile memory 51). Therefore, the conversion rule selection means 6 selects the area on the conversion rule storage means 5 in which the address of "parameter 1" is to be stored, and the conversion rule setting means 7 rewrites the data to "4". If necessary, address "9" of the nonvolatile memory 51 is set to "parameter 1" in the same way.
'' to "1", which is the address on the parameter storage means 3, to obtain the states from addresses "0" to "9" in FIG. 3(b). Next, a method for setting limits on the selection range of parameters will be explained. For example, consider the case where only "parameter 0" and "parameter 4" can be selected and set in FIG. 3(b). To do this, "1" must be set in the area for storing the "upper limit" on the selection range storage means 9 (in the embodiment, address "11" of the nonvolatile memory 51).
All you have to do is set . That is, the data in the area storing the "upper limit" on the selection range storage means 9 is rewritten to "1" by the selection range setting means 11 to obtain the state shown in FIG. 3(b).

Next, the operation when accessing "parameter 4" will be explained. Output “1” of parameter selection means 1
” is the same as the explanation in FIG. 3(a), the address conversion means 4
The bias is added to "6", and the non-volatile memory 5
By reading data "4" from address "6" of 1 and accessing the nonvolatile memory 51 again using this value as an address, "parameter 4" is accessed even though the output of parameter selection means 1 is "1". I can do what I can. Next, the operation when attempting to access "parameter 2" will be explained. The output of the parameter selection means 1 is "2", which is larger than the "upper limit" of "1" of the selection range storage means 9, so the selection range limiting means 8 limits it and outputs the upper limit of "1". Ru. As a result, the same operation as when accessing "parameter 4" occurs, and "parameter 2" cannot be accessed. As described above, according to the parameter setting device of the motor control device of this embodiment, the address conversion rule in the address conversion means 4 can be determined by the contents of the conversion rule storage means 5, and the contents can be converted with the conversion rule selection means 6. Rule setting means 7
The parameters can be arbitrarily determined by the user and each user can rearrange the parameters optimally using the parameter setter, so that it is possible to provide a parameter setting device for a motor control device that is easy to use even when the number of parameters increases. Furthermore, even if the number of parameters increases, the output of the parameter selection means 1 can be limited by the selection range restriction means 8 based on the stored content of the selection range storage means 9, and the content of the restriction is different from the selection range selection means 10. Since the user can arbitrarily determine parameters using the selection range setting means 11, it is possible to provide an easy-to-use parameter setting device for a control device such as a motor that can select and set only the minimum necessary parameters.

(Embodiment 2) A second embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a block diagram showing a parameter setting device of a motor control device according to a second embodiment of the present invention. In FIG. 2, 1 is a parameter selection means, 2 is a parameter setting means, 3 is a parameter storage means, 4 is an address conversion means, 5 is a conversion rule storage means, and 8 is a selection range restriction means for limiting the output of the parameter selection means 1. , 9 is a selection range storage means for specifying the restriction contents of the selection range restriction means 8, and 12 is a selection range storage means for specifying the restriction contents of the selection range restriction means 8; a selection means switching means 13 for setting the target of the parameter setting means 2 to one of the parameter storage means 3, the conversion rule storage means 5, and the selection range storage means 9 according to the setting mode; Means 14 is a setting mode command means for instructing whether to set the contents of the parameter storage means 3, the conversion rule storage means 5, or the selection range storage means 9. The difference from the configuration of FIG. 1 described in the first embodiment is that the conversion rule selection means 6, conversion rule setting means 7, selection range selection means 10, and selection range setting means 11 of FIG. 1 are not provided as independent means. A selection means switching means 12, a setting means switching means 13, and a setting mode commanding means 14 are provided, and when setting the contents of the parameter storage means 3, the parameter selection means 1 is connected to the selection range limiting means 8 via the selection means switching means 12. When connecting the parameter setting means 2 to the parameter storage means 3 via the setting means switching means 13 and setting the contents of the conversion rule storage means 5, the parameter selection means 1 is connected to the parameter storage means 3 via the setting means switching means 13. The parameter setting means 2 is connected to the conversion rule storage means 5 via the setting means switching means 13, and when setting the contents of the selection range storage means 9, the parameter selection means The point is that the means 1 is connected to the selection range storage means 9 via the selection means switching means 12, and the parameter setting means 2 is connected to the selection range storage means 9 via the setting means switching means 13. Therefore, the difference from the first embodiment is in the rearrangement of parameters, the conversion rule selection means 6 and the conversion rule setting means 7.
When the setting mode command means 14 commands the mode for setting the conversion rule without using the setting mode command means 14, the parameter selection means 1 and the parameter setting means 2 are used, and the selection range is restricted, the selection range selection means 10 and the selection range Setting means 11
All that is required is to command the mode for setting the selection range using the setting mode command means 14 and use the parameter selection means 1 and the parameter setting means 2 instead of using the parameter selection means 1 and the parameter setting means 2.

As described above, according to the parameter setting device for a control device such as a motor according to the second embodiment, the conversion rule selection means 6, the conversion rule setting means 7, the selection range selection means 10, and the selection range setting means shown in FIG. Since parameters can be rearranged and selection ranges can be set using parameter selection means 1 and parameter setting means 2 without separately providing 11, it is possible to control motors, etc., which is inexpensive and easy to use even when the number of parameters increases. A device parameter setter can be provided.

In the above embodiment, the parameter storage means 3, the conversion rule storage means 5, and the selection range storage means 9 were explained as being composed of one non-volatile memory, but they may be composed of separate non-volatile memories. Even if it is, it is the same if the part explained as address bias is interpreted as chip select. Further, although the description has been made assuming that the contents of the conversion table are direct addresses, the same applies to calculation formulas for calculating addresses on nonvolatile memory. Furthermore, in the above embodiment, the method of limitation by the selection range limiting means 8 is described as being limited by the upper limit or the lower limit. For example, when the output of the parameter selecting means 1 is greater than the "upper limit", the parameter selecting means From the output of 1, “
It goes without saying that it is also possible to repeat the process of adding the "lower limit value" to the value obtained by subtracting "upper limit value + 1" to keep the value within the selection range.
