Profisafe module for secure communication in the Profinet network

nord07191 The functional safety of machines and systems is of central importance in production. The option module "SK TU4-PNS" from NORD supports easy implementation of safe reactions. Together with a safe PLC, the drive electronics communicate reliably in the existing Profinet network via Profisafe.

functional safety is becoming more and more important as a fundamental component in contemporary machine and system design. The drive specialist is currently supplying frequency converters with integrated STO and SS1 in this area. Safety-related communication and safe movement functions in accordance with IEC 61800-5 are operated with the Profisafe SK TU4-PNS module. Functions such as SLS (Safety Limited Speed), SSR (Safe Speed Range), SDI (Safe Direction), SOS (Safe Operation Stop) and SSM (Safe Speed Monitor) can be integrated and expand the safe stop functions of the drives.

KEB converter Frequency converter innovations: decentralized, networked with app and much more.

nord07192 The Profisafe bus interface monitors the safe compliance with the limit values and provides the safe inputs and outputs. If a limit value is exceeded or fallen below, the bus interface switches to a safe state. All outputs are de-energized, input information is reset and transmitted to the higher-level safety-related controller. This is basically necessary for the use of the Profisafe module.

The integration of the safety functions in the drive offers numerous advantages over a drive solution with discrete safety technology. Less installation space is required, the number of external safety components is lower and the system is modularly scalable. Also he will wiringEffort is reduced to a minimum as only one network cable is required. Another advantage is the global availability of the safety-related machine data.
