Abstract

The invention discloses a simple vector inverter self-learning method with easy implementation, stable and reliable operation and accurate, simple and convenient operation. The method comprises a step of setting a self-learning module on an inverter master controller, a step of presetting an inverter self-learning parameter for system initial installation and debugging and storing the parameter in the self-learning module, a step of setting a self-learning execution element corresponding to the self-learning module at the inverter, allowing the self-learning execution element to call the corresponding inverter self-learning parameter through the inverter master controller, and a step of implementing the self learning of a motor by the inverter.

Description

Vector type frequency converter self-learning method

Technical field

The present invention relates to a kind of electrical installation; Relate in particular to a kind of vector type frequency converter self-learning method.

Background technology

Vector type frequency converter self study process is the identifying to the parameter of electric machine, and its object is to optimize the control performance of frequency converter to motor.

Along with the development of converter technique, RHVC has obtained promoting more and more widely and using in many industries and field.In modern application of frequency converter technology, also more and more higher for the control precision of frequency converter and the requirement of control motor output torque, and vector type frequency converter must carry out self study to reach optimal control performance to motor before use.But, to motor, self study is a very rigorous process to frequency converter, existing traditional method is all to be completed by frequency converter panel operation by professional technological debugging personnel, if the possibility that ordinary person's operate miss likely can cause frequency converter cannot normally work, even burn frequency converter.After the situation such as corresponding electrical machmary maintenance, replacing, change wiring occurs, motor self study again, in view of professional to motor self study operating process of frequency converter, on-the-spot electrician and ordinary person mostly cannot complete.And on-the-spot this need to often the generation the situation of motor again self study of user.All will ask professional commissioning staff to show up at every turn and carry out self study operation, this not only waste of manpower but also waste financial resources, particularly likely can delay and produce the generation that causes waste product.How Predigest vector type frequency converter self study operating process, accomplishes to allow common laborer can complete like a cork this operation and just seems particularly important.

Summary of the invention

The object of the invention is the deficiency existing for above-mentioned prior art, a kind of vector type frequency converter self-learning method is provided.This vector type frequency converter self-learning method is simple, easy to implement, stable, reliable, and operation accurately, simply, conveniently.

Vector frequency converter self-learning method of the present invention is included in frequency converter main controller one self-learning module is set, for the first Installation and Debugging of system are preset frequency converter self study parameter and are stored in self-learning module, in frequency converter, the one self study executive component corresponding to described self-learning module is set, called the corresponding frequency converter self study parameter of self-learning module by this self study executive component by the main controller of frequency converter, implement the self study of frequency converter to motor.

The self-learning method of vector type frequency converter of the present invention is after the situations such as corresponding electrical machmary maintenance, replacing, change wiring occur, frequency converter can promptly and accurately complete self study automatically fast, whole service identifying becomes simply, convenience, effectively save human and material resources and financial resources, significantly reduce production costs.

Accompanying drawing explanation

Fig. 1 is vector frequency converter self-learning method one embodiment control principle structural representation of the present invention.

Embodiment

Now by embodiment, also the invention will be further described by reference to the accompanying drawings.The vector frequency converter self-learning method of the present embodiment is on existing frequency converter electric system basis, for frequency converter itself is set up a self study executive component 5, and in the main controller 3 of frequency converter 1, a self-learning module 4 is set, pre-set frequency converter self study parameter in the time of the first Installation and Debugging of equipment (system), this predefined frequency converter self study parameter comprises the whole relevant operational factor of corresponding motor, after these predefined frequency converter self study setting parameters in the time of the first Installation and Debugging of equipment are good, be stored in the self-learning module 4 of main controller 3 of frequency converter 1, except non-artificial modification or the self-learning module 4 of needing damaged, otherwise this parameter can not change.Motor 2 is connected in frequency converter main frame, and self study executive component 5 is connected in the corresponding input port of the main controller 3 of frequency converter 1; Automatically carry out self study (completing self study operation) by study executive component 5.In reality, self study executive component 5 can be drawn and is arranged on frequency-changer operation panel.In the time that system (frequency converter motor device system) frequency converter in service needs self study, as long as operation self study executive component starts self study relative program, the main controller of frequency converter is transferred the self study parameter in self-learning module automatically, and starts to carry out self study.

It is the one-touch self study mode of frequency converter terminal that self-learning method of the present invention changes traditional self study mode.The model parameter of corresponding motor only otherwise while changing frequency converter and first self study, later frequency converter is again when self study, or else operating personnel need to carry out a series of numerous and diverse operating process by guidance panel, only need press gently a terminal system of next button connection and can realize this function.

Claims

1. a vector frequency converter self-learning method, it is characterized in that, in frequency converter main controller, one self-learning module is set, for the first Installation and Debugging of system are preset frequency converter self study parameter and are stored in self-learning module, in frequency converter, the one self study executive component corresponding to described self-learning module is set, called the corresponding frequency converter self study parameter of self-learning module by this self study executive component by the main controller of frequency converter, implement the self study of frequency converter to motor.
