Product Description:

The DDS03.1-W030-DL20-00 drive controller is produced by Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. As a digital AC servo drive controller, it forms the axis-level interface between a supply unit and a servo motor in automated machinery. By converting command signals from higher-level controls into regulated motor current and voltage, the unit supports precise velocity, torque, and position control in packaging, printing, and material-handling systems. It is intended for cabinet installation where operating conditions remain controlled and predictable.

Within the control cabinet, the drive delivers a continuous output of 30 A, which is the maximum motor phase current it can supply without derating. The housing has an IP20 protection category, which provides finger-safe access but does not protect against liquid entry, so enclosure mounting is required. The allowable ambient temperature range is 0 to 45 °C, and operation outside that range requires derating or additional cooling. Heat is removed by internal air cooling, meaning the unit depends on airflow inside the control cabinet rather than a separate cooling assembly. Command data enters through the single-axis position control interface, allowing direct point-to-point motion commands from a master PLC or motion card.

Altitudes up to 1000 m above sea level are supported before output reduction is required, which allows full current delivery in most factory installations. Rotor feedback signals are processed through digital servo feedback, so the connected motor must use a compatible encoder for closed-loop operation. When the machine is powered down, the unit can remain in storage at temperatures from -30 to 85 °C, which helps protect internal components during transport or long-term storage. The unit is Version 1, which identifies the revision used for this model. These operating limits should be observed during installation and use to maintain proper performance.
