Product Description:

The DDS02.1-W025-DS belongs to the DDS Drive Controllers series produced by Bosch Rexroth Indramat. It is a servo drive controller intended to supply regulated three-phase power to synchronous or induction motors used on coordinated machine axes. By modulating current and voltage in response to encoder signals and fieldbus commands, the unit links motion commands from the PLC to the mechanical load. This makes it a core component in industrial automation cells that require synchronized speed, torque, and positioning. It can be used in packaging systems, transfer lines, and other automated equipment where the motor must respond quickly to changing load conditions.

The drive exchanges cyclic setpoints and status words through its SERCOS interface, a fiber-optic bus that provides deterministic timing for multi-axis coordination. Thermal management relies on internal air cooling, meaning cabinet air is drawn across the heat sink so no external ducts are needed. For rotor position and velocity loops, the controller processes feedback from a motor-mounted encoder using digital servo feedback, which maintains resolution even at low speed. This feedback path helps the drive maintain stable control during slow rotation and rapid direction changes. The unit is part of Line 02, indicating the second platform generation with updated logic and gate drives.

The power stage delivers up to 25 A of phase current without derating, allowing dynamic acceleration on moderate-inertia loads. The unit is a Digital AC Servo Drive Controller and uses Version 1 hardware. Hardware sizing is matched to a single axis whose continuous demand stays within the inverter's semiconductor limits. During operation, the controller exchanges cyclic motion data over SERCOS while regulating motor current to support accurate torque, speed, and position control. A properly matched motor and control loop allow the axis to accelerate, decelerate, and hold speed with predictable response during repetitive machine cycles.
