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

The multi-parameter display frequency converter operation panel comprises a segment code screen, a main controller, a driver, a frequency conversion controller arranged in a frequency converter and a plurality of keys, and the main controller is respectively in communication connection with the frequency conversion controller and the driver; the main controller is used for receiving an input instruction of the key and sending the input instruction to the variable frequency controller; the frequency conversion controller controls the frequency converter according to the input instruction and outputs a feedback instruction; the main controller receives the feedback instruction and sends the feedback instruction to the driver; and the driver is in communication connection with a pin of the segment code screen, and drives the segment code screen according to the feedback instruction, so that the segment code screen displays the latest parameters of the frequency converter. According to the utility model, the driver is adopted to drive the pins of the segment code screen, and the driver can control the segment code screen with more fields by using fewer pins, so that the cost is reduced, the number of parameters displayed in the operation panel of the frequency converter is effectively increased, and the operation state of the frequency converter can be displayed and debugged more visually.
