Geared motors with a built-in frequency converter have been available for years - but many devices have only a limited range of functions. Nord Drive Systems trusts the decentralized drives more and equips them Inverter series SK 200E For close-to-motor and motor-integrated use with the same extensive range of functions as the in-house control cabinet series SK 500E.
Thus, the decentralized converters not only offer a full overload capacity of 200% but also the possibility of positioning the drive with high accuracy. The relative positions (endless axes) or absolute values (rotary tables / fixed, repeatable positions) can be stored in the drive and controlled binary. Alternatively, they can also be specified via a fieldbus system. Position detection can either be performed by incremental encoders - an onboard homing function is part of the basic configuration - or the values of a CANopen absolute encoder are read in directly. The configuration is clear, easy and fast - only very few parameters have to be set for commissioning and optimization.
In addition, it is possible to use the incremental encoder signals for speed control: Thus, an asynchronous motor can achieve unprecedented dynamic performance. Among other things, this concept has proved its worth as a complete alternative to servo drives when used in palletizing machines.
