Product Description:

The DDS02.1-A150-DS01-02-FW is a drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It sits between a motion control system and a three-phase servo motor. The controller shapes commanded torque and speed so that automated axes achieve repeatable positioning, steady velocity control, and synchronized motion in assembly lines, material-handling gantries, and packaging machinery. In coordinated systems, it helps each axis follow the motion profile sent by a PLC or CNC. This supports accurate movement during starts, stops, and load changes.

Fieldbus communication is carried over the SERCOS interface, which lets the controller exchange cyclic setpoints and diagnostic data with a master without proprietary cabling. Rotor position is returned through digital servo feedback, and this encoder method supports high-resolution angle detection for stable speed regulation and accurate position correction. Current delivery is rated at 150 A, enabling the unit to drive large-frame motors through acceleration peaks without saturation. Thermal management relies on external air cooling, which draws ambient air across the heat sink to limit temperature rise inside the control cabinet. This cooling arrangement supports installation in densely populated panels where internal heat buildup can affect neighboring components. Because communication and feedback are both closed-loop inputs, the controller can correct speed deviations quickly during reversals and changing load conditions.

Within the DDS nomenclature, the Function ID is 01 and the product line is 02. The device is a Digital AC Servo Drive Controller, so current vector calculations are handled electronically rather than by analog circuitry, which supports precise closed-loop motor operation. Release level 1 identifies the initial version of this hardware platform. Electronic parameter handling reduces the need for physical adjustments inside the unit. The coding separates this controller from other DDS models with different functions or line assignments.
