Product Description:

The DDS03.1-W030-DS41-01-FW is a drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. As a digital AC servo drive controller, it regulates current and velocity loops for synchronous and induction servomotors used in automated machine tools and material-handling axes. Installed in a multi-axis rack, the unit links the machine control system to the motor power stage. It converts high-level motion commands into precise phase-controlled output that supports coordinated positioning tasks on factory floors and other automated equipment.

The controller communicates with higher-level PLCs over the SERCOS interface, so parameter sets and real-time setpoints travel on a fiber-optic ring with deterministic timing. For motor position data, it relies on digital servo feedback, allowing fine-resolution commutation and closed-loop operation without external feedback converters. A continuous output of 30 A is available for acceleration bursts before the drive enters current limiting. Heat is removed by internal cabinet airflow, which avoids external ducting and keeps enclosure layout simple. Component ingress protection is rated IP20, indicating finger-safe terminals but no sealing against moisture. Within an ambient range of 0 to 45 °C, the power semiconductors can reach rated temperature without derating, supporting line-speed operation in packaging or printing lines.

The drive tolerates storage and transport conditions from -30 to 85 °C, so electronic components remain within allowable stress during non-operating periods. Installation heights up to 1000 m are permitted before output derating applies, which suits typical industrial elevations. The product is part of Line 03 and carries Function ID 01. These identifiers distinguish the unit within the DDS platform and indicate the control version used by this model. This information helps separate the drive from other units in the same product line.
