To avoid safety accidents caused by the unexpected movement of mechanical parts during equipment manufacturing， this paper investigates the safety integrated design method of the servo drive module according to the IEC61800-5-2 standard. First， the principle of servo drive module is clarified by analyzing the mathematical model， hardware structure， and functional architecture of the servo drive. According to the principle， the failure mechanism， failure mode， and effect of failure on the system are discussed. The safe operation interval based on parameter constraint is established， which can actively monitor the dangerous failure of the servo drive module. Then， by analyzing the characteristics of 17 safety functions suggested by IEC61800-5-2， the architecture of safety related system is designed， and a method for safety function integration based on object dictionary is proposed， which can realize the configuration of safety functions according to the specific security requirements. Finally， the experimental platform is built， and the typical safe logic is designed to verify the safety integration method. The experimental results show that the proposed functional safety integration method can effectively implement the IEC61800-5-2 recommended safety functions through configuration， and it meets the requirements of the servo drive module to generalize the safety functions.
