Product Description:

The DDS02.1-A100-DS24-03-FW is a drive controller manufactured by Bosch Rexroth Indramat and supplied in the DDS Drive Controllers series. It is intended for multi-axis automation where one module per axis regulates motor torque and velocity in real time. The unit mounts on a modular backplane beside other DDS devices, forming scalable drive packages for packaging, printing, and material-handling machinery that require precise closed-loop motion control. This arrangement lets the machine builder scale the number of axes without changing the basic cabinet architecture.

The controller delivers a continuous output of 100 A, which is the maximum steady-state motor current it can supply without derating. Communication with higher-level PLCs occurs through a SERCOS interface, and this fiber-optic bus exchanges cyclic position, velocity, and diagnostic data with deterministic timing. Rotor position returns over digital servo feedback, so the drive can process encoder information directly for closed-loop control. Thermal management depends on external air cooling; ambient air drawn from outside the drive panel removes heat from transistors and transformers and helps keep internal temperatures within limits. The unit is a digital AC servo drive controller with embedded processors that execute current, velocity, and position loops, allowing parameter changes through the bus instead of manual potentiometers.

The drive is part of Line 02 and is built in version 1, matching this design generation. It requires a separate firmware subitem matched to the motor type and SERCOS baud rate rather than having the operating code fixed on the board. Because cooling air is pulled from the control cabinet, the enclosure needs unobstructed inlet filters and clear airflow channels to prevent overtemperature shutdown during continuous operation. The cooling path must also remain clear around neighboring modules when the axis runs for long periods at high load.
