The functional safety of electrical drives is generally implemented using certified components and modules; the electrical safety functions, on the other hand, usually take place in the motor controllers or with external safety relay units. For example, all the motor controllers from Festo have an integrated STO (safe torque off).
Product selection in terms of safety is important, but not everything. To help you meet your complex requirements, we not only offer the right products, but our project engineers are also happy to provide you with expert advice – for example, in order to work with you on the possible Failure Mode and Effects Analysis (FMEA). In this way, you can safeguard your planned systems much faster and more cost-effectively.
In practice and because the harmonized standard EN ISO 13849 applies to mechanical as well as pneumatic, hydraulic and electrical controllers, you will often need information on other or general safety functions when working.
A force-generating energy supply to the electric drive is prevented. This function also prevents an unexpected start-up in electric drives.
