Description

  The present invention relates to an inverter device for driving an AC motor at a variable speed and a parameter management method for managing parameter information for driving the AC motor at a variable speed by the inverter device, and more particularly, a parameter management tool separately from an operation panel dedicated to the inverter device. The present invention relates to an inverter device to which can be connected, and a parameter management method for the inverter device.

  In order to perform variable speed drive control of the AC motor by the inverter device, it is necessary to set parameter information of the inverter device according to the user's application. In particular, in order to maximize the performance of the inverter device including the AC motor in consideration of the delay of the control system, it is necessary to set these parameter information correctly. Usually, in order to easily set parameters, an external device such as a personal computer or an operator unit is connected to the inverter device. Therefore, the parameter setting is performed for the inverter device using not only a dedicated operation panel but also a display device or a keyboard of a connected external device.

FIG. 7 is a front view showing an inverter device in which a conventional detachable touch panel is mounted as standard.
In the inverter device 100, a touch panel 200 that can be remotely operated by one touch is prepared as a dedicated display / operation panel. The touch panel 200 is configured to be removable from the inverter device 100 and reattachable.

  Here, a data display unit 201 including a 7-segment LED monitor, a program / reset key 202, a function / data key 203, a selection button (up key and down key) 204, an operation key (RUN) 205, and a stop key (STOP) ) A touch panel 200 including a key operation unit including 206 and an LED display unit 207 is shown. The touch panel 200 can be easily attached to the control panel of the inverter device 100 using, for example, a LAN cable.

  The inverter device 100 further includes a connector (RJ-45) 101 corresponding to RS-485 communication, and can be externally connected to a network using a LAN cable. Therefore, the inverter device 100 has a personal computer connected to the connector 101 of the inverter device 100 as means for displaying the parameter information. When the personal computer is connected, the personal computer is used as a “parameter management tool”. Can be used.

  That is, in the inverter device 100, the touch panel 200 described above displays various parameter data for the inverter device, and not only instructs the operation / stop of the AC motor, but also displays the data on the personal computer, It is also possible to set various function code data or display I / O check, maintenance information, alarm information, and the like.

  However, in reality, the number of parameter information is increased every time a new function is added to the inverter device, while the majority of users of the inverter device use only a part of the functions. In addition, the parameters related to the new functions to be added are divided by operation information (output frequency, output current, output voltage, etc.), program information (menu, function code, function code data, etc.), and alarm information. Parameter information is not registered by serial numbers.

  Therefore, when the user registers the necessary parameters independently from the personal computer connected as a “parameter management tool” from a dedicated display / operation panel such as the touch panel 200, only the necessary parameters are registered. Some have a function of displaying (see Patent Document 1).

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a diagram illustrating a configuration of a parameter management mechanism according to the embodiment.
The parameter management mechanism includes an inverter device 1 for variable speed control of an AC motor (not shown), a personal computer 2 as a parameter management tool, and an operation panel 3. The inverter device 1 includes a first communication unit 11 and a second communication unit 12, a CPU 13 (arithmetic processing unit), and a storage device 14 as communication control units. The personal computer 2 is connected in a communicable state with the CPU 13 of the inverter device 1 via the first communication unit 11. The operation panel 3 is connected to the CPU 13 via the second communication unit 12. As a result, the personal computer 2 can share parameter information with the operation panel 3.

FIG. 2 is a diagram showing a monitor screen displayed on the personal computer by the parameter management tool.
On the screen 20 of FIG. 2, a user group selection unit 21, a parameter display unit 22, direction keys 23, a setting button 24, and a transmission button 25 are displayed. Among these, the user group selection part 21 is a location which selects the user group which a user requires. In this group selection, any one of six groups “overall” and “user 1” to “user 5” displayed in the user group selection unit 21 can be selected.

  The parameter display unit 22 displays a list of parameters in each group. The direction key 23 is used when the user group and parameter of the user group selection unit 21 and the parameter display unit 22 are selected using the up and down keys. The right key and the left key of the direction key 23 are used when the cursor is moved between the user group selection unit 21 and the parameter display unit 22. The operation of the direction key 23 can be substituted by a mouse operation of a personal computer including the following description.

  Here, when “whole” is selected by the user group selection unit 21, the character “whole” which is the group name is inverted. Further, in the parameter display unit 22, all the parameters are displayed by scrolling the screen in the order of the serial numbers from 01 to 08 used for the inverter setting.

  A screen 20 in FIG. 3 is a monitor screen for selecting parameters required by the user. First, the user presses the right key of the direction key 23 to move the cursor from the user group selection unit 21 to the parameter display unit 22 and uses the up and down keys of the direction key 23 to select a parameter to be registered in the user group.

  In this selection operation, the character selected on the parameter display unit 22 is set to an inverted color by pressing the setting button 24, and a predetermined parameter is determined. Here, three parameters “01: frequency setting”, “07: acceleration time”, and “08: deceleration time” are selected. When selecting a plurality of parameters, the above-described parameter determination operation is repeated using the up and down keys of the direction key 23.

  A screen 20 in FIG. 4 is a monitor screen for registering the selected parameter. Here, “01: Frequency setting”, “07: Acceleration time”, “08: Deceleration time”, “40: Torque limit value”, “57: Current detection”, “62: Display filter” are selected. It shall be. In this state, the left key of the direction key 23 is pressed to move the cursor from the parameter display unit 22 to the user group selection unit 21 and the user presses the lower key of the direction key 23 only once to select “user 1”. . When the setting button 24 is pressed next in a state where the character “user 1” of the selected group name is changed to the reverse color, the six selected parameters are registered as the user group of “user 1”.

  When the parameter registration is confirmed, only the parameter selected as the parameter of “user 1” is displayed on the parameter display unit 22. Further, when the transmission button 25 is pressed, the selected parameter information is transmitted to the inverter device 1.

  The parameter information transmitted from the personal computer 2 is received by the first communication unit 11 in the inverter device 1, analyzed by the CPU 13, and registered as a parameter of “user 1” in the storage device 14.

  The operation panel 3 shown in FIG. 1 has a function of selecting an operation function and a protection function of the AC motor, a screen for displaying and operating parameter information thereof, and the same as the parameter management screen of the personal computer 2 described above. It has a user group selection and parameter display function linked to it.

FIG. 5 is a flowchart showing a parameter setting procedure.
In step S1, “whole” displayed on the user group selection unit 21 is selected from the screen 20 of FIG. 2, and parameters required by the user can be selected.

  In step S2, a user selects a necessary parameter from the screen 20 in FIG. In step S3, a plurality of parameters can be selected by returning to step S2 when the setting button 24 is turned on. When the setting button 24 is not turned on, the process proceeds to S4.

  In step S4, parameter selection is completed, and when the cursor is moved from the user group selection unit 21 to the parameter display unit 22, the process proceeds to parameter registration in step S5. In parameter registration, the parameters selected from the monitor screen 20 shown in FIG. 4 are registered as a predetermined user group. If the parameter selection has not ended, the process returns to step S3.

  When the send button 25 is pressed in step S6, the process proceeds to step S7. In step S 7, the parameter information selected as the user group is transmitted to the inverter device 1 and stored in the storage device 14. When the transmission button 25 is not pressed, the process returns to S5.

Next, a procedure for displaying the user group registered in the inverter device 1 on the personal computer 2 will be described.
FIG. 6 is a flowchart showing a parameter display procedure.

  In step S <b> 11, user group selection is performed by the personal computer 2. For example, if the parameter registration of the user group “user 1” is confirmed, when “user 1” is selected by the user group selection unit 21 from the screen 20 of FIG. 2, the transmission button 25 is pressed in step S12. As a result, the process proceeds to the next step S13.

Note that a user group whose parameter registration has not been confirmed on the screen 20 of FIG. 2 cannot be selected.
In step S <b> 13, parameter information included in the user group “user 1” is transmitted from the storage device 14 in the inverter device 1.

In step S14, as shown in the screen 20 of FIG. 4, only the parameters registered as the user group of “user 1” are displayed on the parameter display unit 22.
Similarly, the user group registered in the inverter device 1 can be displayed on the operation panel 3.

  In this case, when “user 1” is selected by the user group selection unit 21, the parameter information registered as a group of “user 1” is requested from the operation panel 3 side to the inverter device 1.

  The CPU 13 in the inverter device 1 extracts the parameter information of the “user 1” group stored in the storage device 14 from the storage device 14 and sends it to the operation panel 3 via the second communication unit 12. Parameter information is transmitted.

As a result, on the operation panel 3, only the parameters of the “user 1” group are displayed by the communication data received from the inverter device 1.
The parameter setting and display procedures have been described above in the case where user group selection is performed by the personal computer 2. However, even when the operation panel 3 is used as a parameter management tool and a user group is selected on the screen, only the parameter number can be displayed. That is, when the parameter number registered as a group of “user X” by the operation panel 3 is displayed on the screen of the parameter management tool on the personal computer 2, communication is performed by the CPU 13 in the inverter device 1 contrary to the above-described route. Data is sent.

  Thus, by sharing the parameter information between the “parameter management tool” on the personal computer 2 and the operation panel 3 dedicated to the inverter device 1, on the personal computer 2 or the dedicated operation panel 3, Only parameter information that the user wants to use can be displayed easily.
