Abstract

The invention discloses a frequency converter monitoring method. The frequency converter monitoring method comprises the steps that a CSV parameter file is called from a CSV parameter file database according to a calling instruction and is analyzed, data information obtained after analysis is stored to an internal storage chain table and displayed in a catalog mode, communication with a frequency converter is carried out through a modbus protocol according to the data information in the internal storage chain table, the working condition information of the frequency converter is obtained, and the data information in the internal storage chain table is updated. Due to the fact that the CSV parameter file is an editable file, when the functions of the frequency converter are modified according to needs of a user, a developer only needs to edit the original CSV parameter file again and modify or add or cancel data content in the original CSV parameter file according to the modification of the frequency converter and does not need to develop or compile the whole CSV parameter file, and therefore field debugging and the integrated development progress are improved.
