Objective： To improve the 45 X-ray diagnostic table’s operation to reduce overshoot and shock to achieve the best operating efficiency. Methods： According to table’s work elements, in-depth analysis has been done on the table’s specific speed curve and problems in practical application. Through the experiment, we gave the corresponding compensation variables to determine the operating parameters. Results： It was confirmed that the diagnostic table’s velocity-time curve was directly related to the table’s operation efficiency and comfort effects. Conclusion： The stress of the paper lies on deduction of the Speed-time curve, which helps Wan Dong 45table’s inverter update the output of DA module during the interruption of timer, so the inverter can have a smooth given speed curve. Thus the motor can start and brake smoothly. In this mode, after more than 200 tests, the table keeps normal movement. It ensures the correctness and feasibility of the amendments.
