NORD Drivesystems' new model of its SK 500E line of control cabinet inverters supports the convenient and free programming of drive-related functions according to IEC 61131. It has all the established features of the series but supports a wider range of drives than any of its sister models; in particular, it can control synchronous motors. It integrates a new universal encoder interface for energy recovery. SK 540E performs even sophisticated tasks without an external PLC, thus saving considerable costs. Pump drives, for instance, can be upgraded with monitoring functions and characteristic curve functions, enabling them to directly react to fluctuating flow rates. The inverter model is also suitable for high-speed cutting processes in turning and milling. It provides the safety function Safe Torque Off as well as sensorless current vector control and an integrated brake chopper for regenerative operation. It also identifies the parameters of the connected motor automatically.
