Product Description:

The DDS02.1-W050-DL04-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. The unit governs the attached servo motor by modulating current and voltage, making it suitable for coordinated motion sequences in automated machinery, material handling stations, and packaging lines. It occupies a modular slot in an Indramat drive rack and serves as the bridge between higher-level PLC commands and the torque-producing windings of the connected servo motor. The controller is intended for rack-based drive systems where compact module spacing and coordinated axis behavior are important to the machine layout. In closed-loop operation, the controller helps the axis follow commanded motion profiles with stable speed and position response during indexing, transfer, and synchronized machine movement.

Position control is handled through an interface that supports single-axis position control, so one DDS02.1 module regulates one mechanical axis at a time. During normal operation, the power stage can deliver a continuous current of 50 A, allowing it to energize mid-range Indramat motors for sustained motion without thermal overload. Thermal management relies on air from inside the control cabinet, which avoids external ducting while supporting normal heat removal inside the rack. Rotor information is returned through digital servo feedback, giving the control loop high-resolution velocity and position data for accurate tracking under changing load conditions. This feedback arrangement supports stable correction of speed and position error as the motor accelerates, runs at constant speed, and decelerates.

The controller uses Function ID version 01, which keeps the parameter set aligned with this drive configuration. The product is part of drive line 02 and is released as version 1. Those identifiers correspond to the assigned hardware generation for this unit and match the mechanical format and connector arrangement used by this controller type. They distinguish this release from other line or version combinations in the platform.
