This article familiarise its readers with possibilities of motor control, measuring frequency and transient characteristics on Yaskawa Motor in laboratory conditions using Matlab – Simulink software and its Real Time Target toolbox. Using the Real Time Target toolbox along with MF624 I/O card, we are able to capture, store and submit information on state variables of the motor in real time. The manufacturer of Yaskawa motors does not provide with information about frequency and transient characteristics of current, speed or position loops. In order to verify the mathematical model, it is necessary to measure these characteristics on a specific motor type and use the obtained results to recalculate amplification of individual controllers by means of the mathematical model. Adjusting the current controller is not possible, since the values are fixed by the manufacturer. The manufacturer allows the user of the current controller to choose from 10 pre-set values (from the „softest“ to the „most stiff“). By making the model more accurate, we may perform simulations of various load states that are approaching real ones
