Nord Drivesystems has added an external 24V control-input option to its entry-level SK2x0E motor-mounted decentralised inverter for energy-optimised applications from pump and fan controls to position- and safety-based systems.

The external control option enables inverter parameter set-up without mains power and offers control availability (including position interrogation) under power-failure conditions where a back-up supply can be used.

The performance-graded SK2xxE product series is directly mounted to a choice of Nord standard or high-efficiency IE2 and IE3-rated motors and gear motors, or supplied as near-motor panel-mounted drives. 

Version options include an AS-I interface with a ’safe-stop’ protocol providing EN954-1-compliant safety, which is particularly suited to large-scale factory automation.
