nord0412Traditional distributed servo solutions are time-consuming and expensive, but have often been the only way to implement positioning applications in remote locations. Here Nord Drivesystems offers the SK series 200E an alternative based on a frequency converter.

The devices with a power range from 0,25 to 22 kW and in sizes from 1 to 4 are the only ones in their class to have integrated positioning control and connection options for incremental and absolute rotary encoders. Thus, the SK 200E series, designed for cost-sensitive applications and suitable for mounting on the motor terminal box, allows the use of standard asynchronous motors even for applications requiring relative or absolute position control. The integrated positioning control "Posicon" provides programming of up to 63 absolute positions. The desired positions can also be transmitted via a fieldbus interface. In addition, up to six step sizes (so-called position increments) can be stored in the frequency inverter.

For all tasks, the distance calculation of the positioning control ensures a time-optimized and safe journey to the destination. Despite the cost-effective device design, all inverters in the basic version offer extensive features: in addition to encoder evaluation and positioning control, an integrated brake chopper, an electromagnetic brake control unit and high-quality sensorless current vector control ensure that the specified position is maintained even under heavy load fluctuations.

In addition, customers can choose from a wide range of options for adapting the devices to their own wishes using internal and external expansion options. At www.sk200e.de an own website informs about features and areas of application of the frequency inverters.
