Embodiment Construction

[0020] The present invention is applied to an AC servo system. The parameters in the AC servo system are generally divided into three categories: current parameters, default parameters and optimal parameters. The current parameters are those directly involved in the operation and control of the motor. They run on the on-chip RAM of the digital signal processor (DSP) and can be modified online. After the digital signal processor is powered off, it will not be saved. The optimal control parameters need to be adjusted slowly according to different types of AC servo motors or in different environments, until a set of parameters that enable the motor to work in a good state is finally found. The default parameters are a set of default parameters provided to prevent the motor parameters from being modified or mis-operated so that the AC servo motor cannot operate normally. This set of parameters can make the motor run normally, but may not make the motor work in the best condition. . Th...

Abstract

The invention discloses a device for automatically recognizing the model and parameter of an AC servo motor and a method thereof. The device comprises an AC servo motor which is provided with an absolute type encoder and a servo driver which drives the AC servo motor; wherein, the absolute type encoder comprises a first memory which stores the model of the AC servo motor; the servo driver comprises a data signal processor which is provided with a second memory, the second memory stores a plurality of groups of models of AC servo motors and the default parameters corresponding to the models. The data signal processor reads out the default parameter which corresponds to the model of the AC servo motor from the second memory according to the model of the AC servo motor in the first memory. The device and method of the invention automatically recognizes the model and parameter of the AC servo motor without memorizes the models of different motors by human, thus has the advantages of conveniently operation and safety in use for the operators.

Description

Technical field [0001] The invention relates to a device and method for automatically identifying the model and parameters of an AC servo motor. Background technique [0002] At present, parameter intelligent management has been widely used in AC servo devices. However, the adjustment of AC servo motor parameters is a very laborious task. It needs to be adjusted slowly according to different types of AC servo motors or in different environments. Until you are satisfied, you can finally find a group that makes the motor work in good condition. The following parameters, we call them the optimal control parameters. Usually, the optimal parameters are solidified in the external memory on the control board. AC servo motor parameters are also divided into current parameters and default parameters. The current parameters are the parameters directly involved in the control of the motor operation. Generally, they run on the on-chip RAM of the DSP and can be modified online. After the DSP ...
