The frequency converter configuration system comprises the frequency converter and a frequency converter manufacturer function module software providing side. The frequency converter configuration method and the frequency converter configuration method, disclosed by the invention, are simple in operation and low in cost, and can meet the using requirements in more occasions.

Description

technical field [0001] The invention relates to a method for configuring a frequency converter, and also relates to a frequency converter configured by the method and a frequency converter configuration system. Background technique [0002] Inverters generally refer to devices that use microelectronics technology to control power semiconductor devices to drive motors. The frequency converter has a wide range of applications. With the progress of society and the development of industrial automation, its application fields have also expanded, covering various fields from industry, commerce to civil use. Although the main function of the frequency converter is to control the motor, due to the wide variety of applications, the operating modes of the control motor are also very different. [0003] At present, the mainstream design of the inverter is to use function code configuration to adapt to different applications. The function code download function refers to the built-in m...

Problems solved by technology

Since the function code configuration is a pre-written inverter function application, there are many restrictions on adapting to unknown needs. In many cases, the inverter cannot meet the actual needs of users, so it is necessary for the inverter manufacturer to develop another Complete inverter control software to meet user needs; in addition, due to the limitation of inverter storage space, the application of pre-written inverter functions is limited, so in actual use, the function code configuration often only supports part of the inverter functions application, so that the scope of adaptation of the function code is limited

[0004] In order to solve the above-mentioned defects of the frequency converter using the function code configuration, some manufacturers use the built-in programmable logic controller (PLC) in the frequency converter to realize the function expansion requirements. To realize this function, the current specific method is to use The high-performance processor has a built-in programmable logic device function, or adds additional programmable logic device hardware, so that on the one hand, the cost of the inverter is greatly increased and the application of the inverter is limited; on the other hand, due to the programmable logic device Users are required to write software according to specific needs, which puts forward higher requirements for customers and raises the threshold for users
