Distributed inverter series covers universal application range

Paul Boughton
SK 200E series frequency inverters from NORD DRIVESYSTEMS provide solutions with adaptable functions for any application within a distributed automation concept where cost-efficient drives with a performance between 0.25 and 22 kW are required.
Available for installation near the motor or as motor-integrated models, various types cover all typical distributed applications.

Frequency inverters from the SK 2x0E line, for instance, are equipped with a process and PI controller, and qualify for use with fans and pumps through their internal 24 V power supply and two analogue inputs.

By contrast, the SK 2X5E line is tailored for the needs of conveyor technology. Inverters from this series are equipped with a brake controller and two integrated potentiometers which allow for easy adaptation to the requirements of any drive task.

Thanks to standard features such as speed feedback (servo mode) and a positioning function (POSICON), these inverters can also independently and precisely control positioning and lifting tasks.

The units are performance-graded and can be fitted with various optional add-on functions, allowing users to choose suitable compact devices with the exact feature range for any given task, thereby optimising resource use. The feature list of all basic models includes sensorless current vector control, a brake chopper, incremental encoder evaluation, POSICON positioning control, and energy saving functions.

A plug-in memory module (EEPROM) enables users to quickly and easily exchange parameter sets with other units of the same type. In addition to standard fieldbus options, the inverters are also available with an integrated AS interface as well as the STO Safe Torque Off and SS1 Safe Stop 1 safety functions certified by German testing authority TÜV. The inverters are primarily designed for direct installation on the terminal box of geared motors. NORD provides additional services, pre-configuring these fully integrated drive units for operation in the field with the required protection class (optional: ATEX zone 22 / 3D). The robust, reliable and economic drive units are available in sizes 1 to 4 with a maximum output of 22 kW.
