Functional Safety entails the detection of a potentially dangerous condition resulting in the activation of a protective or corrective device or mechanism to prevent hazardous events arising or providing mitigation to reduce the consequence of the hazardous event.
In the design of a machine, a risk assessment must be performed and then updated regularly. As far as possible, the machine should be designed to be inherently safe, so that hazards are eliminated from the basic design. However, in most cases some risks remain at an unacceptable level and must be actively reduced using suitable control measures.
The integration of motion safety functions in the drive supports a decentralised approach to the machine's functional safety that brings many benefits
