Distributed inverter range has increased options

The comprehensive and performance graded SK2xxE product series is directly mounted to a wide choice of NORD standard or high efficiency IE2 and IE3 rated motors and gearmotors (or supplied as near-motor panel mounted drives). With power ratings from 0.25 to 7.5 kW, from single and three phase supplies, the inverter features an advanced sensorless current vector drive with a broad selection of standard and optional control and fieldbus communications features. The complete product series suits energy optimised applications from pump and fan controls to sophisticated position based and safety based systems. The modular and scalable inverter allows users to select only those options that are relevant and necessary for their application, keeping costs to a minimum but with flexibility to upgrade systems in the field if required.

Entry level built-in features include Class A line filtering, EEPROM parameter storage, brake management, encoder feedback and basic positioning control. A status and diagnostics console provides I/O status LEDs and RS232/485 communications interfacing. Version options include an AS-I interface with a 'Safe-Stop' protocol providing EN954-1 compliant safety which is particular suited to large scale factory automation. More advanced features are available through direct programming or with externally mounted control box options. Known as SimpleBox and ParameterBox, these options cover a potentiometer adapter for manual speed controls and a tactile keypad for parameter set-up and status displays.

The SK2xxE product series also includes a selection of expansion card options called Technology Boxes that extend the capability to include Profibus, CANopen and DeviceNet for direct parameter adjustment as well as expanded machine I/O. NORD Drivesystems has also recently introduced an EtherCAT network version. A dedicated website at www.sk200e.de presents the full range of models, features, and application areas in detail.
