NORD DRIVESYSTEMS supplies all frequency inverters with integrated STO (Safe Torque Off) and SS1 (Safe Stop 1). The drive specialist provides fail-safe communication and safe movement functions according to IEC 61800-5 with the NORD SK TU4-PNS PROFIsafe module. In combination with a safety PLC, the drive electronics reliably communicate over the existing PROFINET via PROFIsafe.
The module monitors the safe compliance with the limit values and provides safe inputs and outputs. If a limit value is exceeded or undershot, the bus interface switches to a safe state. The voltage is disconnected from all outputs, input information is reset and transmitted to the higher level fail-safe controller. This is essential for the use of the PROFIsafe module.
The PROFIsafe module NORD SK TU4-PNS supports the safety functions SLS (Safety Limited Speed), SSR (Safe Speed Range) and SSM (Safe Speed Monitor).
With the PROFISAFE module with decentralised FI, customers can implement their drive solutions with integrated safety functions from the NORD modular drive systems.
