Nord has extended its SK 5xxE line of frequency inverters by size 5 and 6 models. In addition to the 0.25 to 7.5 range, users can also choose inverters up to 22 kW. The easy-to-use units are suitable for all stand-ard bus systems. All models offer user-friendly, standardised configuration and parameterisation. The inverters up to 7.5 kW are available as SK 500E, 510E, 520E and 530E models. In 11 kW and beyond models, there are SK 515E and SK 535E types. All inverters share basic functions, such as brake management and a brake chopper, a PID and process controller and an automatic magnetization adjustment option. Specific models have extra functions: The SK 515E in the sizes 5 and 6 features the safety function “Safe Stop” and an integrated CANopen interface. The SK 535E comes with an additional encoder input and the Posicon position controller, which allows users to implement a relative or absolute position control. The SK 515E and the SK 535E are equipped with an external 24 V supply for the control card.
