Digital operator used in frequency converter and picture display method used in operator

Abstract

The invention discloses a digital operator used in a frequency converter and a picture display method used in the operator. The digital operator is connected with an external computer, and one editing software in the external computer can be used for editing a picture of the digital operator and downloading the edited picture to a liquid crystal display module of the digital operator for display.The digital operator is provided with a plurality of functional keys, and the corresponding functions of all the functional keys can be defined at discretion by means of the editing software. In sucha way, the digital operator is endowed with better flexibility, and the digital operator can be programmed into conditions most accordant with the requirements and closest to user habits by a user atdiscretion.

Description

technical field [0001] The present invention relates to a frequency converter, in particular to a controller for controlling the frequency converter. Background technique [0002] In the field of industrial control products, the medium of communication and interaction between various electromechanical systems and operators is very important. For frequency converters, the above-mentioned medium is used to control the frequency converter and display the frequency converter. The digital manipulator of information. [0003] At present, the most common inverters on the market are equipped with digital operators that display information with LEDs, such as figure 1 As shown in , it is a schematic diagram of the interface in the prior art. A first manipulator 1 of the prior art mainly uses a plurality of control keys 11 to set the frequency converter and switch display information, so that after the first manipulator 1 obtains various values ​​of the frequency converter, It is di...

[0006] However, although the second manipulator 2 can completely display the information of the frequency converter through the LCM 22, the screens it can display are already set when the original factory produces them, and the user can only watch the existing screens to obtain Inverter Information

Moreover, although these function keys 23 can be used by the user to perform specific functions more quickly, their corresponding functions are all defined when the original factory produces them, and the user cannot change them.

For example, if one of the function keys 23 is defined as displaying the running time of the frequency converter, but the user does not need to know the running time of the frequency converter, the corresponding functions of the function keys 23 cannot be displayed. is redefined, leaving the user with one less button to use
