Product Description:

The DDS03.1-W050 is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It translates motion commands from CNC or PLC systems into regulated three-phase outputs that drive synchronous and induction servomotors for coordinated positioning, speed control, and torque control on multi-axis machinery. By supervising motor feedback and fault states, the unit helps protect equipment while maintaining the response accuracy required in machine tools, printing presses, and automated handling cells. Because the control stage continuously processes feedback data, commanded motion can remain stable during acceleration, deceleration, and changing load conditions.

This controller can deliver up to 50 A of continuous output current without thermal derating under its stated operating conditions. Cooling relies on air from inside the control cabinet, so heat moves through the module’s heat sink by internal enclosure airflow rather than a separate external blower. Component ingress protection is rated IP20, which guards against accidental finger contact and requires installation inside a control cabinet for broader protection. Reliable operation is permitted from 0 to 45 °C, and installation altitude is allowed up to 1000 m. This cooling method depends on cabinet airflow being able to pass through the enclosure space around the drive.

When the machine is idle or in transit, the drive may be stored within -30 to 85 °C. The unit is part of Line 03 and is version 1. These codes identify the product variant within the DDS range and help distinguish it from other revisions in the same product family. The stated storage range applies when the equipment is not operating, allowing the module to be kept in controlled storage areas before installation or reuse.
