The article shows how the drive modelling depending on the required output information, focusing on the machine tool area. In this way, the simulation process can be optimally set up and the output information from the model environment can be used efficiently. From the selection of input parameters to the detail and accuracy of the output values of the model itself. Many authors are dealing with digital twins of production machines. However, they treat the actual drive part of the machine tool as a black box. However, its function occupies a significant part in the creation of such a model. On the other hand, the second part of the authors focus specifically on the actuator modeling, but they do not consider the methodological approach according to the need of output information. This is related to the negative impact on the impracticality of deploying such models in real applications.
