Problems solved by technology

[0004] However, the above two inverter parameter setting methods have certain shortcomings. First, manual setting of each device parameter is a waste of time, and it is easy to make mistakes in setting, which requires high professionalism of the parameter setting personnel; The method requires the help of computers and 485 communication module tools. Inverter manufacturers must also specially develop and provide PC host computer software to customers. Both are indispensable. Every device needs to be wired, and the operation efficiency is low. In many cases, there is no such operation on site. For example, the place where the equipment is placed is narrow, or the tool line we bring is not long enough to connect to the computer, etc., the dependence on external equipment is high, and the operation is complicated

Embodiment 1

[0048] see figure 1 , figure 1 It is an implementation flowchart of the inverter parameter setting method in the embodiment of the present invention, which is applied to the keyboard of the inverter, and the method may include the following steps:

[0049] S101: When it is detected that the first inverter control board generates a parameter upload status flag, receive each parameter to be set sent by the first inverter control board.

[0050]The hardware structure of the inverter is mainly divided into the following three parts: the inverter drive circuit, the inverter control board, and the inverter keyboard. Among them, the inverter control board and the inverter keyboard each have a programmable control CPU chip, and the two CPU chips can exchange data with each other through 485 communication. When it is necessary to copy the parameters in inverter A to inverter B, first install the inverter keypad in inverter A, and the inverter control board of inverter A is the first ...

Embodiment 2

[0060] see figure 2 , figure 2 It is another implementation flowchart of the inverter parameter setting method in the embodiment of the present invention, which is applied to the keyboard of the inverter, and the method may include the following steps:

[0061] S201: When it is detected that the first inverter control board generates a parameter upload status flag, receive each parameter to be set sent by the first inverter control board according to the keyboard initialization data.

[0062] Wherein, the keyboard initialization data includes the total number of parameters to be set, the number of parameter groups, and the number of parameters in each group.

[0063] When it is necessary to copy the parameters in inverter A to inverter B, you can first initialize the keyboard of the inverter used for parameter copying according to the current parameter setting task to obtain the keyboard initialization data. The keyboard initialization data may include the total number of ...

Abstract

The invention discloses a frequency converter parameter setting method. The method comprises the following steps: receiving to-be-set parameters transmitted by a first frequency converter control panel when it is detected that the first frequency converter control panel generates a parameter uploading state mark; judging whether all the to-be-set parameters are received or not; and if yes, when itis detected that the second frequency converter control panel generates a parameter downloading state mark, sending all the to-be-set parameters to a second frequency converter control panel, whereinthe first frequency converter control panel and the second frequency converter control panel are control panels of two different frequency converters. By applying the technical scheme provided by theembodiment of the invention, automatic setting of the parameters of the frequency converter is realized without depending on external equipment, the parameter setting process is greatly simplified, and the parameter setting efficiency is improved. The invention further discloses a frequency converter parameter setting device, frequency converter parameter setting equipment and a storage medium, which have corresponding technical effects.

Description

technical field [0001] The present invention relates to the technical field of frequency conversion, in particular to a frequency converter parameter setting method, device, equipment and computer-readable storage medium. Background technique [0002] When using the inverter, the user can set the parameters of the inverter according to the actual needs of the equipment. For example, some applications have very high requirements for control performance, and it is necessary to optimize the debugging parameters to realize the software function. [0003] There are mainly two ways to set inverter parameters: one is that after the technical service personnel of the manufacturer or the senior application engineer of the customer debug a device according to the instructions provided by us, record the debugged function codes and parameter values ​​in the notebook, For devices with the same sequence, manually set each function code parameter value of each device according to this func...
