PROFIsafe module for drive-based safe motion control
Nord Drivesystems says its new SK TU4-PNS PROFIsafe interface module provides customers with an option to integrate functional safety with Profinet communications on its decentralised motor-mounted inverter drives and centralised drives installed in cabinets.
PROFIsafe is claimed to be the world's leading and most widely used technology for safety applications for production and process automation. With SIL3, PLe (Performance Level e) and Category 4, the fail-safe communication protocol fulfils the stringent safety requirements. In combination with a safety PLC, the drive electronics reliably communicate via PROFIsafe in Profinet.
Safe inputs and outputs - for emergency stop switches and light barriers, for example - can be connected to the application with plug connectors. A rotary encoder can be connected to supervise the safe drive function. The new Nord module is equipped with two redundantly operating microprocessors and is self-monitoring.
Various safe motion functions can be easily integrated and therefore extend the safety stop functions of the drive units:
- SLS (Safety Limited Speed)
- SSR (Safe Speed Range)
- SDI (Safe Direction)
- SOS (Safe Operation Stop)
- SSM (Safe Speed Monitor)
With this, the PROFIsafe module provides comprehensive safety for the reliable operation of plant and machinery.
The module is suitable both for control cabinet installation as well as decentralised installation, and is available for the Nordac Link, Nordac Flex and Nordac Pro inverter series.
