SK 200E: geared motors with a smart head for positioning tasks
NORD DRIVESYSTEMS SK 200E inverters are available for installation near the motor or as motor-integrated models, with the same wide functional range as the centralized SK 500E series of cabinet-installed inverters. The decentralized frequency inverters not only provide an ample overload capacity of 200%, but also enable users to position the drive with high precision. The relative positions (incremental or endless axes) or absolute values (rotary tables / fixed, repeatable positions) can be controlled with binary values through the SK 200E’s inputs and stored within the drive. Alternatively, they can be set via a fieldbus system. Positions can be detected via incremental encoders (an onboard referencing function is included in the inverters' basic equipment), or position values provided by a CANopen absolute encoder may be directly imported. Configuration is easy, fast, and concise – only a few parameters need to be set for commissioning and optimization.
Moreover, the encoder signals can be used for speed control, which enables an unprecedented dynamic performance from asynchronous motors. This approach has proven a viable alternative to servo drives, e.g. in palletizers (see video linked via QR code). For such and similar scenarios, NORD provides individually assembled decentralized drive solutions from a single source.
