Here, the communication unit 120 may communicate with the copy destination inverter. For example, the communication unit 120 may perform Ethernet-based communication, and may communicate with the inverter 300 through the Ethernet switch 200 .

The display unit 130 may display a setting web page provided by a web server provided in the copy destination inverter. For example, the display unit 130 may be a display device such as an LCD, OLED, or a touch screen panel.

The communication unit 310 may provide a setting web page by performing communication with the setting copying apparatus 100 . For example, the communication unit 310 performs Ethernet-based communication in the same manner as the communication unit 120 of the setting copy device 100 and communicates with the setting copy device 100 or another inverter through the Ethernet switch 200. there is.

The memory unit 320 may store the setting of the corresponding inverter. Here, the inverter setting may include parameters and network information.

Also, when the inverter 300 is a copy destination inverter and the compatibility check is performed in the inverter, the memory unit 320 may store the parameter mapping table. Here, the parameter mapping table is for checking inverter compatibility and may be a parameter comparison table for each inverter model.

In addition, when the inverter 300 is the copy destination inverter, the memory unit 320 may temporarily store the network address of the copy source inverter input to the setting web page through the setting copy device 100 .

The control unit 330 may be communicatively connected to the communication unit 310 and the memory unit 320 to control the overall operation of the inverter 300 . For example, the controller 330 may be a microprocessor.

The control unit 330 may control to provide a setting web page to the setting copying apparatus 100 through the communication unit 310 when the setting copying apparatus 100 accesses the inverter 300 through the web.

In addition, when the inverter 300 is a copy destination inverter, the control unit 330 may communicate with the copy source inverter according to a setting copy command of the setting copy device 100 to request a setting of the copy source inverter. In this case, if it is selected to copy only a part of the settings, the controller 330 may control to copy only the selected item among the settings transmitted from the copy source inverter.

In this case, if it is requested to copy only a part of the setting, the controller 330 may control to transmit only the selected setting item.

4 is an exemplary diagram for explaining the operation of the web-based inverter setting copy system according to an embodiment of the present invention.

As shown in the figure, in order to copy the settings of the second inverter 300-B to the first inverter 300-A, the setting copying device 100 allows the user to configure the network of the first inverter 300-A. When an address is input, a setting web page may be requested from the first inverter 300 -A based on the input network address. In this case, the first inverter 300 -A may provide a setting web page to the setting copying apparatus 100 as a response.

When the user inputs the network address of the second inverter 300-B to copy the settings and selects copy execution, the settings copy apparatus 100 transfers the settings of the second inverter 300-B to the second inverter 300- It can be commanded to the first inverter (300-A) to transmit and copy to B).

At this time, according to the command of the setting copy apparatus 100, the first inverter 300-A requests the setting value from the second inverter 300-B based on the input network address of the second inverter 300-B. and the second inverter 300-B may transmit the requested setting value as a response to the second inverter 300-B. Here, the set value may be an inverter parameter.

In addition, the setting copying apparatus 100 copies the setting value transmitted from the first inverter 300-A from the second inverter 300-B to the first inverter 300 through the setting web page so that the user can check it. -A) setting status can be displayed.

On the other hand, if the network address of the second inverter 300-B is manually input, there is a possibility of copying an inappropriate inverter setting due to an incorrect input.

To solve this, the setting copying apparatus 100 may display identification information of the second inverter 300 -B corresponding to the input network address on the setting web page. Here, the identification information may include at least one of an installation location of the inverter corresponding to the input network address, installation information, and manufacturing information.

Accordingly, in one embodiment of the present invention, since the copy source inverter can be easily identified through the identification information, it is possible to prevent the wrong designation of the copy source inverter due to an input error of the network address.

As another example, the setting copy apparatus 100 may request to input the model name of the inverter corresponding to the input network address. That is, the setting copy apparatus 100 may double input information of the second inverter 300-B, such as a corresponding model name, together with a network address.

Accordingly, an embodiment of the present invention can accurately recognize the radiation source inverter and prevent input errors, thereby ensuring the reliability of accurate information input of the radiation source inverter.

As another example, the setting copying apparatus 100 may input the network address of the second inverter 300-B through the QR code or IR tag of the second inverter 300-B. That is, the setting copy device 100 recognizes the QR code or IR tag of the second inverter 300-B, extracts the network address included in the QR code or the IR tag, and the network of the second inverter 300-B It can be entered automatically as an address.

Accordingly, in one embodiment of the present invention, since the network address of the copy source inverter can be automatically and accurately input without manual input, incorrect information input can be prevented and input stability can be improved.

Optionally, the setting copying apparatus 100 may command to copy only a part of the parameters of the second inverter 300-B according to a user's selection. In this case, the setting copy apparatus 100 may select a copy item of the first inverter 300 -A displayed on the setting web page by the user.

For example, the setting copying apparatus 100 may request the first inverter 300-A to copy only the setting value of the item selected by the user from among the setting values transmitted from the second inverter 300-B. In this case, the first inverter 300 -A may copy only the selected item among the set values transmitted from the second inverter 300 -B.

As another example, the setting copy apparatus 100 may instruct the first inverter 300 -A to request only the copy item selected by the user to the second inverter 300 -B. In this case, the first inverter 300 -A may designate a corresponding parameter when requesting a set value. Accordingly, the second inverter 300 -B may transmit only the setting values for the items requested from the first inverter 300 -A to the first inverter 300 -A.

In addition, the setting copy apparatus 100 is configured to transmit the data from the first inverter 300-A to the second inverter 300-B before the first inverter 300-A and the second inverter 300-B are requested. ) can be checked for compatibility. Here, the setting copy apparatus 100 may determine whether at least one of an inverter model, a parameter version, and an inverter function and use is the same as a compatibility check. In this case, when at least one of an inverter model, a parameter version, and an inverter function and use is the same, the setting copy apparatus 100 may determine that it is compatible.

When the compatibility check result is different, the setting copy apparatus 100 may determine whether parameter mapping is performed through the parameter mapping table. Here, the case in which the compatibility check result is different is the case in which the same determination items are different.

For example, the setting copying apparatus 100 may determine whether to map parameters by determining whether the parameter range of the second inverter 300-B is within the parameter range of the first inverter 300-A.

As another example, the setting copying apparatus 100 may determine whether the parameter mapping is performed by determining whether the parameter range of the second inverter 300-B is convertible within the parameter range of the first inverter 300-A. .

In this case, when parameter mapping is impossible, the setting copy apparatus 100 may display a warning message on the setting web page. Here, the warning message is a message indicating that parameter mapping is impossible or parameter copying is not suitable.

On the other hand, if forced copy is selected by the user even when parameter mapping between the first inverter 300-A and the second inverter 300-B is not possible, the setting copy apparatus 100 performs the second inverter 300-B ) may be copied to the first inverter 300-A.

Such compatibility check may also be performed by the first inverter 300 -A. That is, after receiving the setting copy command from the setting copying apparatus 100 , the first inverter 300 -A may perform a compatibility check for setting copying.

Accordingly, an embodiment of the present invention can induce the setting of a specific inverter or a new inverter to be copied to the setting of the inverter having the same or most similar parameters, thereby ensuring the stability of the inverter setting copy.

Meanwhile, since the inverter 300 controls a high-capacity motor, a malfunction may result in personal injury. Therefore, it is necessary for the first inverter 300 -A to check whether setting, particularly, copying of parameters is normally performed.

In this case, when the first inverter 300-A receives the setting value transmitted from the second inverter 300-B, it may determine whether there is an error based on the parameter setting value and the entire set of parameters. For example, the first inverter 300 -A may determine whether there is an error in the set value transmitted from the second inverter 300 -B using a cyclic redundancy check (CRC).

Also, before the first inverter 300-A copies the set value transmitted from the second inverter 300-B, the parameter range transmitted from the second inverter 300-B does not match its parameter range. If not, the setting may be copied by linearly converting the parameter range of the second inverter 300-B or converting by a conversion table. That is, when there is a slight difference between the parameters of the first inverter 300-A and the parameters of the second inverter 300-B, the parameters of the second inverter 300-B are set within the parameter range of the first inverter 300-A. can be approximated as

Accordingly, an embodiment of the present invention can minimize the difference in characteristics of the inverter due to the difference in the parameter setting range of the radiation source inverter and the copy destination inverter.

On the other hand, when the first inverter 300-A is replaced with the second inverter 300-B, the set value copied from the second inverter 300-B is the network information of the second inverter 300-B. may include more. That is, the first inverter 300 -A may request network information as well as parameters as a set value to the second inverter 300 -B. Also, the first inverter 300 -A may update its own network information with the network information transmitted from the second inverter 300 -B. Here, the network information may include overall setting information for performing Ethernet communication through the Ethernet switch 200 .

In this case, the second inverter 300 -B may transmit the requested network information to the first inverter 300 -A. At the same time, the second inverter 300 -B may change its own network information to a manufacturing initial value.

Accordingly, in one embodiment of the present invention, even when replacing the new inverter 300-A with the existing inverter 300-B, network collision between two inverters connected to the same network during the setting copy process can be prevented. .

5 is an exemplary diagram of an inverter setting web page of a web-based inverter setting copying system according to an embodiment of the present invention.

As shown in the drawing, the setting web page 130a is provided by the web server of the inverter 300 and may be displayed on the display unit 130 of the setting copying apparatus 100 . The setting web page 130a includes a copy destination network address 131, a copy source network address 132, a parameter item 133, network information 134, a copy button 135, a cancel button 136, an identification information ( 137) and a model name input field 138 may be included.

The copy destination network address 131 may be a network address of the corresponding inverter 300 . That is, the copy destination network address 131 may be the network address of the copy destination inverter input by the user.

The copy source network address 132 is for indicating the network address of the copy source inverter, and network information input by the user may be displayed. That is, the copy source network address 132 is initially displayed as blank, and the corresponding network address can be displayed according to an input from the user.

At this time, when the QR code or IR code is recognized for the inverter 300 , the network address included in the QR code or the IR tag may be automatically input to the copy source network address 132 .

The parameter item 133 indicates the parameters of the copy destination inverter. Here, the parameter item 133 may include a parameter name and parameter setting value. In this case, the parameter item 133 may include a checkbox for each parameter so that the user can set the copy item.

The network information 134 indicates network information of the copy destination inverter. Here, the network information 134 may include information on a network configured based on the Ethernet switch 200 .

The copy button 135 and the cancel button 136 may be input by a user to instruct execution of copying. The copy button 135 is a button for performing setting copy, and the cancel button 136 is a button for canceling setting copying.

The identification information 137 indicates identification information of the inverter corresponding to the copy source network address 132 by the user. Here, the identification information may include at least one of an installation location of the inverter corresponding to the copy source network address 132 , installation information, and manufacturing information.

The model name input field 138 is an item input by the user together with the copy source network address 132 and indicates the model name of the copy source inverter. At this time, if the information in the model name input field 138 is not suitable for the copy source network address 132, the setting web page 130a may display an error message so that the user can recognize it.

The setting web page 130a described above is an example, and it is self-evident that it may be configured in various ways according to functions.

6 is an exemplary diagram of a parameter mapping table of a web-based inverter setting copy system according to an embodiment of the present invention.

As shown in the drawing, the parameter mapping table may include set values of parameters P1 to PN for each model M1 to M3. Here, the set value of the parameters P1 to PN may be in a numerical range or a specific value, like the P1 parameter, but is not limited thereto. For simplification and illustration of the drawings, parameters P2 to PN are indicated by alphabets.

In this case, the setting copy apparatus 100 or the first inverter 300 -A may perform a compatibility check according to the parameter range of the inverter.

For example, when the model of the first inverter 300-A is M3 and the model of the second inverter 300-B is M1, the range of the P1 parameter is that the first inverter 300-A is the second inverter ( 300-B), so they are directly compatible.

However, if the model of the first inverter 300-A is M2 and the model of the second inverter 300-B is M1, the range of the P1 parameter may not be directly compatible because some non-overlapping parts occur. there is.

In this case, the first inverter 300 -A may convert the P1 parameter of the second inverter 300 -B to fit the P1 parameter range of the first inverter 300 -A according to the conversion table. As another example, when the setting value of the P1 parameter 1-9 is not in the universal use range, it can be set to be used in the range of 10 to 50 except for this.

On the other hand, when the model of the first inverter 300-A is M3 and the model of the second inverter 300-B is M1, as described above, they are directly compatible, but in this case, the first inverter 300- The performance of A) may not be fully utilized.

Hereinafter, a web-based inverter setting copy method according to an embodiment of the present invention will be described with reference to FIGS. 7 to 9 . Here, the web-based inverter setting copy method may be a method performed in the web-based inverter setting copy system 10 .

7 is a flowchart of a web-based inverter setting copy method according to an embodiment of the present invention.

In the web-based inverter setting copy method 400, first, the setting copy device 100 sets a network interface (step S410). In this case, the setting copy apparatus 100 may set a network interface for accessing a network configured based on the Ethernet switch 200 .

Next, the setting copy apparatus 100 accesses the web to the first inverter 300-A according to the network address input by the user (step S420). In this case, the setting copying apparatus 100 may receive and display the setting web page 130a from the first inverter 300 -A.

Next, the network address of the second inverter 300-B is input by the user (step S430). In this case, the setting copy apparatus 100 may receive the network address of the second inverter 300 -B through the input unit 110 such as a keyboard.

Alternatively, the setting copy device 100 may receive the QR code or IR code of the second inverter 300-B, and automatically input the network address according to the QR code or the IR code.

Next, the setting copying apparatus 100 determines whether to copy only a part of the parameter (step S440), and when the user selects to copy only part of the parameter, it receives the selection of the parameter to be copied (step S450). In this case, the user may select some of the displayed parameters of the setting web page 130a.

As a result of the determination in step S440, when the user selects to copy all parameters or does not select a particular parameter, the setting copy apparatus 100 may omit the selection of parameters to be copied (step S450).

Next, when the user instructs to copy the setting through the setting web page 130a, the setting copy apparatus 100 generates a command for setting copy and transmits it to the first inverter 300-A (step S460). Here, the setting copy command may be a command for the first inverter 300-A to request a setting from the second inverter 300-B to receive the setting from the second inverter 300-B.

Next, the setting copying apparatus 100 performs a compatibility check of the setting value, in particular, the parameter (step S470). In this case, the setting copy apparatus 100 may perform a compatibility check between the first inverter 300 -A and the second inverter 300 -B based on a previously stored parameter matching table. Here, the parameter compatibility check may be performed by the first inverter 300 -A. A detailed description of the parameter compatibility check will be described later with reference to FIG. 8 .

Next, the first inverter 300-A polls a parameter from the second inverter 300-B (step S480). That is, according to the copy command of the setting copy apparatus 100, the first inverter 300-A transmits the set value to the second inverter 300-B according to the input network address of the second inverter 300-B. Upon request, the second inverter 300 -B may transmit the requested setting value to the first inverter 300 -A.

In this case, the first inverter 300 -A may check the error of the parameter transmitted from the second inverter 300 -B by using the CRC.

Next, the first inverter 300-A executes parameter copying (step S490). That is, the first inverter 300-A copies the parameters transmitted from the second inverter 300-B to its own parameters and completes the setting. In this case, the setting copy apparatus 100 may display the setting state of the first inverter 300 -A through the setting web page so that the user can check it.

8 is a flowchart of a compatibility check of a web-based inverter setting copy method according to an embodiment of the present invention. Here, the compatibility check may be selectively performed in the setting copying apparatus 100 or the first inverter 300-A, and the following description will be made based on the setting copying apparatus 100 .

The compatibility check method 470 first determines whether the setting copy device 100 has different inverter models or parameter versions (step S471). Optionally, the setting copy device 100 may determine whether the inverter function and use are different in addition to the inverter model or parameter version.

As a result of the determination in step S471, when it is determined that at least one of the inverter model, parameter version, and inverter function and use is the same, the setting copy apparatus 100 may end the compatibility check and proceed to step S480.

As a result of the determination in step S471, when it is determined that at least one of the inverter model, parameter version, and inverter function and use is different, the setting copy apparatus 100 checks the parameter mapping table (step S427). In this case, the setting copy apparatus 100 may compare ranges of each parameter of the first inverter 300-A and the second inverter 300-B through the parameter mapping table.

As a result of checking the parameter mapping table, when parameter mapping is not possible, the setting copy apparatus 100 may end the compatibility check and proceed to step S480 . For example, when the parameter range of the second inverter 300-B is within the parameter range of the first inverter 300-A, the setting copy apparatus 100 ends the compatibility check.

As a result of checking the parameter mapping table, when parameter mapping is impossible, the setting copying apparatus 100 displays a warning message on the setting web page 130a (step S474).

Next, the setting copying apparatus 100 determines whether the user selects the forced copy (step S475), and ends the setting copying if the forced copy is not selected.

As a result of the determination in step S475, if the user selects forced copy, the setting copying apparatus 100 proceeds to step S480 to copy the settings.

9 is a flowchart of network information copying of a web-based inverter setting copying method according to an embodiment of the present invention.

The network information copying method 500 first determines whether the first inverter 300-A is a replacement of an existing inverter after parameter copying (step S490) (step S510). In this case, whether to replace the existing inverter may be selected by the user before the copy instruction in step S460. For example, in the setting copy apparatus 100 , a selection of whether to replace the existing inverter may be input by the user through the setting web page 130a. In this case, the setting copy apparatus 100 may transmit whether to replace the existing inverter when the setting copy command is commanded to the first inverter 300 -A. Here, the existing inverter is the second inverter 300-B, and the new inverter is the first inverter 300-A.

As a result of the determination in step S510, when it is determined that the existing inverter is not replaced, the first inverter 300-A finishes copying the settings.

As a result of the determination in step S510, when it is determined that the existing inverter is to be replaced, the first inverter 300-A requests network information from the second inverter 300-B (step S520). In this case, the second inverter 300 -B may transmit the corresponding network information to the first inverter 300 -A according to the request of the first inverter 300 -A. At the same time, the second inverter 300 -B may change its own network information to an initial value during manufacturing.

Next, the first inverter 300-A updates its own network information with the network information transmitted from the second inverter 300-B (step S530).

The above methods may be implemented by the web-based inverter setting copy system 10 as shown in FIG. 1, and in particular, may be implemented as a software program performing these steps, in this case, these programs are It may be stored in a readable recording medium or transmitted by a computer data signal coupled with a carrier wave in a transmission medium or a communication network. In this case, the computer-readable recording medium may include any type of recording device in which data readable by a computer system is stored.
