Abstract

The invention discloses a frequency converter system based on data sharing. The frequency converter system comprises a first frequency converter and a second frequency converter, wherein the first frequency converter comprises: a first memory module used for storing configuration data and operation data of the first frequency converter; and a first communication module which is used for enabling the first frequency converter to communicate with the outside. The second frequency converter comprises: a second memory module used for storing configuration data and operation data of the second frequency converter; and a second communication module which is used for enabling the second frequency converter to communicate with the outside, wherein the first frequency converter and the second frequency converter form data interaction through the first communication module and the second communication module so as to enable data of the first memory module to be transferred into the second memorymodule. The frequency converter system based on data sharing has the advantages that data can be transplanted, and therefore data availability and deployment efficiency are improved.

Description

technical field [0001] The present application relates to a frequency converter system, in particular to a frequency converter system based on data sharing. Background technique [0002] Inverter (Variable-frequency Drive, VFD) is a power control device that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's operating power supply. [0003] The frequency converter is mainly composed of rectification (AC to DC), filter, inverter (DC to AC), braking unit, drive unit, detection unit, micro-processing unit, etc. The frequency converter adjusts the voltage and frequency of the output power supply by switching off the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the frequency converter has many protection functions , such as overcurrent, overvoltage, overload p...
