Fig. 2 is a schematic flow chart of a method for controlling a frequency converter according to an embodiment of the present application. As shown in fig. 2, the inverter control method may be applied to a control apparatus installed with an inverter configuration program for configuring an inverter that controls a motor and an automatic operation program for the inverter configuration program, the inverter control method including:
s210: the automatic operation program starts the frequency converter configuration program.
The automatic operation program can be configured according to an external interface of the frequency converter configuration program. And calling an external interface by the automatic operation program to access a logic module of the frequency converter configuration program and execute a corresponding function. The frequency converter configuration program may be, for example, startdriver debugging software, startup debugging software, scout debugging software, and the like, which is not limited in this embodiment.
S220: the automatic operation program acquires configuration parameters of the frequency converter, wherein the configuration parameters comprise equipment parameters of the frequency converter and equipment parameters of the motor.
The device parameters of the frequency converter may comprise one or more of the following: the type of the frequency converter, the network address information of the frequency converter, the order number of the control unit of the frequency converter, the firmware version of the control unit of the frequency converter, the order number of the power unit of the frequency converter, the bus message and the like. The device parameters of the motor may include one or more of: motor nameplate data, such as motor rated current, motor rated power, motor power factor, motor rated speed, etc.; motor control methods, etc. In some implementation manners, the configuration parameters of the frequency converter may further include user-defined parameters and the like, which is not limited in this embodiment.
In one implementation manner of the present application, the obtaining, by the automatic operation program, the configuration parameter of the frequency converter may include: and reading a preset parameter configuration table by an automatic operation program to obtain configuration parameters for configuring the frequency converter.
The parameter configuration table may be a pre-created parameter configuration table with a specific file format, for example, the parameter configuration table may be in the form of E × cel. The parameter configuration table may include information such as the above-mentioned device parameters of the frequency converter, the device parameters of the motor, and other user-defined parameters. When the automatic operation program obtains the configuration parameters of the frequency converter, the automatic operation program can analyze the parameter configuration table to obtain various configuration parameters in the parameter configuration table.
In the implementation mode, the parameter configuration table can be read by an automatic operation program when the frequency converter is configured, so that the acquisition efficiency of the configuration parameters of the frequency converter is improved, and meanwhile, the parameter configuration table can be directly read by a configurator, so that the configurator can conveniently and quickly acquire the configuration parameters of the frequency converter when needed.
In another implementation manner of the present application, an automatic operation program calls the frequency converter configuration program to open a saved configuration item, where the saved configuration item includes configuration parameters of a frequency converter; the automatic operation program obtains the configuration parameters of the frequency converter from the saved configuration items so as to improve the efficiency of obtaining the configuration parameters.
S230: an automatic operation program inputs configuration parameters to the frequency converter configuration program.
Specifically, the frequency converter configuration program has items to be configured associated with the frequency converter configuration, which items to be configured include, for example, an order number and a firmware version of a control unit of the frequency converter, an order number of a power unit of the frequency converter, a network address of the frequency converter, motor nameplate data of a motor controlled by the frequency converter, and the like. And the automatic operation program inputs corresponding configuration parameters in each item to be configured in the frequency converter configuration program.
In a specific implementation manner, before the automatic operation program inputs the configuration parameters to the frequency converter configuration program, the automatic operation program calls the frequency converter configuration program to create a configuration item corresponding to the frequency converter, and the automatic operation program inputs the configuration parameters of the frequency converter in the configuration item.
For example, items to be configured associated with the frequency converter configuration, such as an order number and a firmware version of a control unit of the frequency converter, an order number of a power unit of the frequency converter, a network address of the frequency converter, and a motor nameplate data waiting configuration item of a motor controlled by the frequency converter, are added to the configuration item. And the automatic operation program inputs corresponding configuration parameters in each item to be configured in the configuration items so as to finish inputting the configuration parameters in the frequency converter configuration program.
S240: the automatic operation program sends a device configuration instruction to the frequency converter configuration program, and the device configuration instruction instructs the frequency converter configuration program to transmit configuration parameters to the frequency converter so as to configure the frequency converter.
In one example, the automation program may control display of a first prompt on a display interface of the electronic device, the first prompt indicating whether to transmit the configuration parameters to the frequency converter. In response to a first user operation indicating transmission of configuration parameters to the frequency converter, the automation program sends a device configuration instruction to the frequency converter configuration program to cause the frequency converter configuration program to transmit the configuration parameters to the frequency converter to configure the frequency converter.
In another example, the automation program may proactively send device configuration instructions to the frequency converter configuration program to cause the frequency converter configuration program to transmit configuration parameters to the frequency converter to configure the frequency converter.
In the embodiment of the application, the configuration parameters of the frequency converter can be automatically acquired through the automatic operation program, and the automatic operation program can be used for controlling the starting, calling and the like of the frequency converter configuration program to automatically complete the configuration of the frequency converter, so that the configuration efficiency and the reliability of the frequency converter are improved, and meanwhile, the configuration personnel does not need to master the configuration steps and the operation sequence, and the requirement on the configuration experience of the configuration personnel is reduced.
It should be understood that the above steps S210 to S240 may be performed when the control device is in communication connection with the frequency converter, i.e. when the frequency converter is on-line, or may be performed when the control device is not in communication connection with the frequency converter, i.e. when the frequency converter is off-line. For convenience of description, the steps S210 to S240 performed when the frequency converter is online may be referred to as online configuration or online debugging, and the steps S210 to S240 performed when the frequency converter is offline may be referred to as offline configuration or offline debugging.
Optionally, in an embodiment of the present application, after step S240, the automatic operation program calls the inverter configuration program to send a motor initialization command to the inverter, the motor initialization command instructing the inverter to perform static identification and dynamic optimization on the motor.
Static identification refers to the inverter detecting a current returned from the motor by sending a constant voltage to the motor, and detecting parameters of an equivalent model of the motor, such as stator resistance, stator inductance, rotor resistance, rotor inductance, and mutual inductance of the motor, from the returned current. The dynamic optimization means that when a vector control mode is adopted, the frequency converter measures the rotational inertia of the motor during loaded operation, and optimizes the proportional coefficient, the integral time constant and the like of a speed ring. The frequency converter performs static identification and dynamic optimization on the motor, so that the vector control of the frequency converter on the motor can obtain better performance.
In a specific implementation manner of the application, when the automatic operation program calls the frequency converter configuration program, the communication connection between the frequency converter configuration program and the frequency converter is established based on the network address information of the frequency converter; and the automatic operation program calls a frequency converter configuration program to send a motor initialization instruction to the frequency converter based on the communication connection so as to instruct the frequency converter to dynamically optimize the motor. Because the configuration parameters comprise the network address information, the automatic operation program can automatically call the frequency converter configuration program to carry out network configuration based on the network address information, and the automation of the configuration process is further improved.
In this embodiment, the automatic operation degree respectively instructs the frequency converter to perform static identification and dynamic optimization on the motor by calling the frequency converter configuration program twice. For example, the degree of automatic operation may invoke a converter configuration program to send a motor initialization command to the converter instructing the converter to statically identify the motor. After the static identification is completed, the degree of automatic operation may again invoke the inverter configuration program to send a motor initialization command to the inverter instructing the inverter to dynamically optimize the motor. Therefore, static identification and dynamic optimization of the motor can be realized by using an automatic operation program to control calling of a frequency converter configuration program and the like, and efficient online debugging of the frequency converter is realized.
It should be understood that step S240 is performed in a case where the control device is in communication connection with the inverter, i.e., the inverter is on-line.
Optionally, in an embodiment of the present application, after step S240, the automatic operation program may further send a device batch configuration instruction to the frequency converter configuration program, where the device batch configuration instruction instructs the frequency converter configuration program to transmit the configuration parameters to another frequency converter having the same type as the frequency converter, so as to configure the another frequency converter.
Wherein, the same type means that the types of the frequency converters are the same.
Specifically, the automatic operation program may control to display a second prompt message on a display interface of the electronic device, where the second prompt message indicates whether to configure the frequency converters in batch. In response to a second user operation indicating a batch copy of the frequency converter, the automation program sends a batch configuration instruction to the frequency converter configuration program to cause the frequency converter configuration program to transmit the configuration parameters to a further frequency converter of the same type as the frequency converter to configure the further frequency converter. Therefore, full-automatic batch configuration of the plurality of frequency converters can be realized, time is saved, and efficiency is improved.
It should be understood that the sending of the device batch configuration instruction from the automatic operation program to the frequency converter configuration program may be performed after step S240, for example, after the automatic operation program sends the device configuration instruction to the frequency converter configuration program to instruct the frequency converter configuration program to configure the parameters, and for example, after the automatic operation program calls the frequency converter configuration program to send the motor initialization instruction to the frequency converter to instruct the frequency converter to perform static identification and dynamic optimization on the motor, which is not limited in this embodiment.
Optionally, in an embodiment of the present application, after step S240, the automatic operation program calls the frequency converter configuration program to send a configuration saving instruction to the frequency converter, where the configuration saving instruction instructs the frequency converter to save the configuration parameters.
In the configuration process, the configuration parameters are stored in the RAM of the frequency converter, so that the control unit of the frequency converter can be accessed at any time. In order to ensure that the configuration parameters are saved in the event of a power failure of the frequency converter, the configuration parameters temporarily stored in the RAM of the frequency converter need to be stored in a non-volatile memory of the frequency converter, for example in an EEPROM of the frequency converter. In the embodiment, the automatic storage of the configuration parameters by the frequency converter can be realized by calling the frequency converter configuration program through the automatic operation program, so that the human operation errors possibly caused by the fact that an operator does not know the storage mechanism of the frequency converter are avoided.

s310: the automatic operation program starts the frequency converter configuration program.
S320: and the automatic operation program calls the frequency converter configuration program to create a configuration item corresponding to the frequency converter.
In a particular implementation, the automation program displays a third prompt on the display interface of the control device, the third prompt indicating whether to create the configuration item. In response to a third user action for instructing the creation of the configuration item, the automation program calls the converter configuration program to create the configuration item. For example, in a case where a corresponding frequency converter has not been configured before, i.e., the frequency converter is configured for the first time, a configuration item corresponding to the frequency converter needs to be created. At which point the user may perform a third user action indicating the creation of a configuration item. After that, the configuration item is entered, and items to be configured related to the frequency converter configuration are added in the configuration item, such as the order number and the firmware version of the control unit of the frequency converter, the order number of the power unit of the frequency converter, the network address of the frequency converter, and the motor nameplate data of the motor controlled by the frequency converter to wait for the configuration item. If the frequency converter is configured before, the automatic operation program calls the frequency converter configuration program to open the saved configuration item, and the automatic operation program obtains the configuration parameters of the frequency converter from the saved configuration item.
S330: and the automatic operation program acquires the configuration parameters of the frequency converter.
S340: the automatic operation program inputs the configuration parameters of the frequency converter in the configuration items.
Specifically, the automatic operation program inputs corresponding configuration parameters in each item to be configured in the configuration items to complete inputting the configuration parameters in the frequency converter configuration program.
S350: the automatic operation program sends a device configuration instruction to the frequency converter configuration program, the device configuration instruction instructing transmission of configuration parameters to the frequency converter for configuring the frequency converter.
S360: and the automatic operation program calls a frequency converter configuration program to send a configuration storage instruction to the frequency converter, and the configuration storage instruction instructs the frequency converter to store the configuration parameters.
S370: and the automatic operation program calls the frequency converter configuration program to save the configuration items.
Specifically, the configuration parameters are input in the configuration items during the configuration process, but the configuration parameters are not stored in the non-volatile memory EEPROM of the control device. In this embodiment, the automatic operation program calls the frequency converter configuration program to save the configuration items, so that the automatic saving of the configuration parameters in the EEPROM of the control device can be ensured, and human operation errors possibly caused by the fact that an operator does not know the storage mechanism of the control device can be avoided.
In this embodiment, the specific processes of steps S310 to S360 can refer to the embodiment shown in fig. 2, and are described herein for avoiding repetition.
Optionally, in an embodiment of the present application, after step S350, the automatic operation program calls the inverter configuration program to send a motor initialization command to the inverter, the motor initialization command instructing the inverter to perform static identification and dynamic optimization on the motor.
Optionally, in an embodiment of the present application, after step S340, the automatic operation program may further send a device batch configuration instruction to the frequency converter configuration program, where the device batch configuration instruction instructs the frequency converter configuration program to transmit the configuration parameters to another frequency converter having the same type as the frequency converter, so as to configure the another frequency converter. Therefore, full-automatic batch configuration of the plurality of frequency converters can be realized, time is saved, and efficiency is improved.
In the embodiment of the application, the configuration parameters of the frequency converter can be automatically acquired through the automatic operation program, and the automatic operation program can be used for controlling the starting, calling and the like of the frequency converter configuration program to automatically complete the configuration of the frequency converter, so that the configuration efficiency and the reliability of the frequency converter are improved, and meanwhile, the configuration personnel does not need to master the configuration steps and the operation sequence, and the requirement on the configuration experience of the configuration personnel is reduced.
