Getting to Know the Indramat DDS Drive


Indramat’s DDS (Digital Drive System) drives include 2.1 and 2.2 drives, which were made in 14 power ranges,and the 3.1 and 3.2 drives, which came in two power ranges.

The difference between the 2.1 and the 2.2, and the difference between the 3.1 and the 3.2, are not differences you can see on the outside. They differ only in the version of the firmware they use.

None of these drives are still being made, but there are plenty of legacy units out there.

The DDS drives were designed to provide precise and reliable control of electric motors in various industrial applications. These drives played a crucial role in automating and optimizing processes in industries such as manufacturing, packaging, and automation.

Key features of Indramat DDS drives include:

  • Digital Control: The DDS drives used digital control technology to ensure accurate and responsive control of servo motors. This allowed for precise positioning and speed control in industrial machinery.
  • Modular Design: DDS series drives are modular, which gives flexibility for configuration. You can stack multiple drives with a single power source. This modularity allows for easier maintenance and troubleshooting. Users could replace or upgrade specific modules without having to replace the entire drive unit.
  • Communication Protocols: DDS drives supported various communication protocols, enabling integration with different control systems and networks. This flexibility in communication is crucial in the context of industrial automation.
  • Feedback Systems: To ensure accurate control and positioning, DDS drives incorporated feedback systems such as encoders. These systems provide real-time information about the motor’s position and speed, allowing the drive to make adjustments as needed.
  • User-Friendly Interfaces: Indramat drives feature user-friendly interfaces for configuration and monitoring. This makes it easier for operators and maintenance personnel to interact with the drive system. The H1 display on the front of the drives gives you essential information about the operating status of the drive and alerts you to any faults or issues, including problems with cables.

These drives can use Sercos modules; if they do, there will also be H2 displays on the Sercos modules.

What if you have a DDS drive?

You probably aren’t in the market for a DDS drive if you don’t already have one. Most likely, you have one or more in your facility and maybe you worry about keeping them in running order, since they are legacy units.
