Parameter setting device for motor soft starter

Abstract

The invention discloses a parameter setting device for a motor soft starter. The parameter setting device mainly comprises an infrared transmitting and receiving module, a microcontroller module, a storage module and a display circuit, wherein an input end of the microcontroller module is electrically connected with an output end of the infrared receiving module; the microcontroller module is interacted with the display circuit and the storage device; when a control key on an infrared remote controller is pressed down, the infrared transmitting and receiving module communicates and stores the data into the storage module through the microcontroller module, the control key on the infrared remote controller is adjusted by observing data on a liquid crystal display, the data of the storage module is further changed, and finally, start-up parameters of a soft starter of a three-phase alternating current asynchronous motor needed to be set in the starting process are set. Therefore, the defects that the parameter setting circuit board is extremely large, the wiring is complicated and excessive input / output (I / O) ports are occupied in the traditional soft starter can be overcome, and the parameter setting device is convenient to use.

Description

technical field [0001] The invention relates to a motor parameter setting device, in particular to a parameter setting device of a motor soft starter. Background technique [0002] The starting methods of the three-phase AC asynchronous motor soft starter include ramp-up starting, current-limiting starting, etc. During the starting process, starting parameters including starting time, initial trigger angle, and limited current value need to be set. [0003] At present, the parameter setting of most soft starters is realized by means of keys, etc. The biggest disadvantage is that the parameter setting is complicated, and the circuit board of the conventional matrix keyboard is too large, the wiring is complicated, and it occupies too many I / O ports, which is very inconvenient. Contents of the invention [0004] In order to overcome the above-mentioned deficiencies in the prior art, the object of the present invention is to propose a parameter setting device of a motor soft ...
