The NORDAC FLEX SK 205E has a large power range of 0.33 – 30 HP, a compact design, and allows high precision in synchronous and positioning applications via integrated POSICON control. Another advantage is the precise and rapid current vector control that ensures constant speeds with fluctuating loads. The SK 205E also offers maximum flexibility and energy efficiency, especially during partial load operation.

<h2>Flexible and Efficient: Features of NORDAC FLEX Variable Frequency Drives</h2>

NORDAC FLEX variable frequency drives can be installed close to drives in the field or integrated onto their motors. Plug-and-play power and data cable connections are available to make set up extremely easy, and the decentralized system enables short motor/encoder cables as well as short supply cables to sensors. FLEX VFDs come in 4 sizes and can be used to control standard asynchronous motors, high-efficiency synchronous motors, and brake motors.

With the FLEX VFD series, encoder feedback can be realized for applications such as position-controlled transport systems. These VFDs feature 4 digital inputs and 1 digital output, and their high overload capacity makes dynamic movements with short start and stop times or cyclic operation possible. The gear unit can also be monitored via an optional NORDAC ACCESS BT Bluetooth interface paired with the NORDCON APP software. With this system, errors can be quickly diagnosed and remedied to prevent unscheduled maintenance and downtime. Drive parameterization is also possible via the integrated diagnostic interface that comes with the free NORDCON software tool.

The SK 205E features a total of six digital and two analog interfaces, two encoder interfaces, and one integrated PLC for programming functions close to the drive. A wide range of extensions through optional modules are possible as accessories. For example, a communication interface that supports commercially available Ethernet dialects as well as extensions for functional safety such as PROFIsafe and STO.

The NORDAC FLEX SK 205E is a feature-rich, versatile part of the NORDAC family of variable frequency drives.
