Industrial automation systems have revolutionized manufacturing and processing industries, improving efficiency and productivity. However, with the increasing complexity of machinery, ensuring worker safety has become a significant challenge. Safe Torque Off (STO) is an essential safety feature in industrial automation system. Its key design is to mitigate risks and protect personnel and machinery.
What is Safe Torque Off
Safe Torque Off (STO) is a critical part of the overall functional safety framework compliant with international standards such as IEC 61508 and ISO 13849. The primary purpose of STO is to ensure the controlled and safe deactivation of the torque produced by electric motors. This stops the motion of machinery in a controlled and secure manner. It allows for the decoupling of the motor from the load, ensuring that it cannot generate any motion or torque.
