Product Description:

The DDS02.1-W025-DA02-01-FW belongs to the DDS Drive Controllers series produced by Bosch Rexroth Indramat. This unit is a drive controller that pairs with modular power supplies to run AC servo motors in multi-axis machinery, giving coordinated velocity and position regulation in industrial automation cells. It receives setpoint commands from higher-level motion cards and converts them into regulated three-phase output for torque, speed, or position loops. That arrangement helps neighboring axes share a common power platform while still allowing each channel to respond independently to machine commands. Compact cabinet layouts also benefit because the controller and supply modules are separated by function rather than combined into one large unit.

The controller exchanges setpoints and diagnostics through an analog interface, permitting ±10 V velocity or torque commands from PLC modules. Heat is removed by internal air cooling, a method that uses cabinet airflow and avoids the need for external ducting. The power stage provides a continuous output of 25 A, which suits axes that operate within this current range during normal load conditions. Rotor position returns via digital servo feedback, allowing high-resolution closed-loop control without separate signal converters. The unit is version 1, identifying the first release for this design. This combination of input, cooling, current capacity, and feedback support makes the controller suitable for servo systems that need stable response and direct integration with existing analog command hardware.

The internal feature set uses 01 as the function ID version, which standardizes diagnostics, limit processing, and error handling for this controller type. The line designation is 02, placing the unit within the corresponding DDS product grouping. Classified as a Digital AC Servo Drive Controller, the device is intended for use with compatible Rexroth motors and modular supplies in closed-loop servo systems. Its control structure processes command and feedback data in the same unit, which supports accurate motion response when load conditions change during operation. The result is a controller format suited to coordinated axis control in automated production equipment.
