AI Technical Summary

Technical Problem

Existing inverter operation panels display limited data and are difficult to operate. In particular, segment code screens occupy a large number of I/O ports, making it difficult for the main controller to control the inverter. Non-professionals cannot obtain the inverter status at once, and users face difficulties in debugging.

Method used

The main controller and the driver are connected in communication. The driver drives the pins of the segment code screen to display the latest parameters of the frequency converter. The main controller and the frequency converter communicate through the RS-485 protocol and the RJ-45 interface, using fixed-length binary instruction transmission and multiplexing technology to control more segments of the segment code screen.

Benefits of technology

It achieves a more intuitive multi-parameter display, reduces costs while increasing the number of parameters displayed, simplifies the operation process, and facilitates debugging the inverter's operating status.

Abstract

This invention proposes a multi-parameter display inverter operation panel, including a segment code screen, a main controller, a driver, an inverter controller located within the inverter, and multiple buttons. The main controller is communicatively connected to both the inverter controller and the driver. The main controller receives input commands from the buttons and sends these commands to the inverter controller. The inverter controller controls the inverter according to the input commands and outputs feedback commands. The main controller receives the feedback commands and sends them to the driver. The driver is communicatively connected to the segment code screen via pins and drives the segment code screen according to the feedback commands, enabling the segment code screen to display the latest parameters of the inverter. This invention proposes using a driver to drive the pins of the segment code screen. The driver can control a segment code screen with more fields using fewer pins, effectively increasing the number of parameters displayed on the inverter operation panel while reducing costs. This facilitates a more intuitive display and debugging of the inverter's operating status.
