Apparatus and method for automatically recognizing AC servo motor model number and parameter

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 ...

Problems solved by technology

But this has the following disadvantages: Since one AC servo motor corresponds to one model, when it is necessary to restore the default value of its parameters, it is necessary to manually input the motor model to the device to make it the model corresponding to the current motor. Therefore, debugging Personnel need to remember the models of different AC servo motors, resulting in inconvenient use and error-prone
