NORD extends functional safety of its drive electronics

In automated production, drive electronics with integrated safety functions enable safe control and monitoring of all motion sequences. Functional safety is therefore also becoming increasingly important in drive systems from NORD and is being continuously extended. The decentralised NORDAC ON frequency inverter now receives an extensive safety upgrade.

Safe control of speeds

In addition to STO and SS1, the safe motion functions SLS, SMS and SSM are now also integrated for fail-safe control of the rotary movement. The NORDAC ON thus not only features safe standstill functions (Safe Torque Off and Safe Stop 1) but also enables safe control of a drive solution's speeds (Safety Limited Speed, Safe Maximum Speed and Safe Speed Monitor).

The future variant of the decentralised frequency inverter can be integrated into a fail-safe application within an existing Industrial Ethernet network via PROFIsafe or FSoE. The desired Industrial Ethernet dialect is simply parameterised during commissioning. Stand-alone use is possible as well.

The safe digital inputs and outputs of the NORDAC ON can be used to incorporate fail-safe peripheral components or functions. This enables the connection of, for example, emergency stop buttons, safety door switches or photoelectric sensors. Two safe one-channel digital inputs can be combined into one safe two-channel digital input and two safe outputs can be combined into one safe two-channel output.

Made for modern production environments

The decentralised NORDAC ON frequency inverter is characterised by its compact design and full plug-in capability. Thanks to its plug-and-play functionality, it significantly reduces the wiring effort and provides a maintenance-friendly, economical solution for modern production environments. It also features PLC on board for PLC and drive-related functions. It can process data from connected sensors and actuators, initiate control sequences and communicate drive and application data to the control centre, networked components or to cloud storage. NORDAC ON is available for a power range from 0.37 kW to 3.7 kW.
