SK 200E : Geared motors with a smart head for positioning tasks
Combined with encoders, distributed
drives from NORD enable flexible and
convenient positioning solutions
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.
Company background
NORD DRIVESYSTEMS develops, produces and sells drive technologies with around 2,800 employees, and is one of the international leaders in the industry. In addition to standard drives, NORD supplies application-specific concepts and solutions, even for special applications, for example with energy-saving drives or explosion-protected systems. The annual sales in the 2011 fiscal year amounted to about 412 million Euro. The company founded in 1965 now has over 35 subsidiaries worldwide. The closely meshed sales and service network ensures optimum availability for short delivery times and customer-oriented services.
NORD produces a wide variety of drive units for torques from 10 to 200,000 Nm, electric motors with powers from 0.12 kW to 200 kW as well as the necessary power electronics in the form of frequency inverters and servo controllers. Inverter solutions are available for classical installations in the switch cabinet and for decentralised and fully integrated drive units.
