VLT® Decentral Servo Drive DSD 510

Flexible modularity for decentral servo applications

The VLT® Decentral Servo Drive DSD 510 extends the VLT® FlexMotion™ decentral servo drive concept. Supporting a wide range of feedback encoders and sensorless control, its architecture is completely open and allows you to choose your preferred PM or ACM motor.

Use the integrated motion controller to run the motion sequence independently and therefore free up the central PLC.

Fast and fail-safe installation

The Plug and Twist hybrid cabling concept, including supply and control voltage as well as functional safety and fieldbus wires, makes the installation fast, easy, fail-safe end cost-efficient. Since multiple decentral drive units can be powered by the combination of just one VLT® Power Supply Module PSM 510 and VLT® Decentral Access Module DAM 510 through simple daisy chain wiring, no distribution boxes are required, and you can reduce cabling to a minimum.

Choose your preferred protocol

Open connectivity to common real-time Ethernet systems, such as EtherCAT, POWERLINK and PROFINET, IEC 61131-3 based programming and PLCopen certified Motion libraries makes the system even more flexible and easy to integrate into various engineering environments.

High performance in harsh environments

A completely smooth and easy-to-clean surface together with high-protection IP67 enclosure and vibration resistance class 3M7 ensures the perfect fit for all kind of rotating applications in demanding environments.
