The large direct drive motors and encoders form together with the control system a high performance telescope exhibiting very high tracking accuracy. This paper describes the integration and fine-tuning of the VLT Drive Systems. It discusses the different problems encountered during the integration. The servo model that was used to simulate the problems and to find new solutions is described as well as test results and advanced analysis methods.
