Product Description:

The DDS03.1-W030-D is a digital AC servo drive controller built by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. Within an automation cell, the unit supplies regulated three-phase power to matched synchronous or induction servomotors, translating command signals from a higher-level CNC or PLC into precise torque and speed commands. By integrating the controller close to the motion axis, the system can reduce panel wiring and support fast motor response in packaging, material-handling, and assembly lines. This layout helps maintain repeatable axis behavior during changing load conditions.

The drive delivers up to 30 A peak current for short acceleration bursts while maintaining 10 A continuous current during steady operation. Power is sourced from a 300 V DC bus, and the basic electronics draw 150 mA at ±15 V and 500 mA at +24 V for logic and relay circuits. Cooling relies on internal air cooling, meaning cabinet air passes through the heat sink before being expelled. Protection against accidental contact is provided by the IP20 ingress rating. The controller reads motor position through digital servo feedback, allowing closed-loop velocity and position regulation. Line code 03 and version 1 identify the product generation of this model.

For reliable service, the device is specified for rated operation between 0 °C and 45 °C, with output derated when the surrounding air rises to 55 °C. Installation is permitted up to 1000 m above sea level without additional cooling aids, and air at the site must not exceed 25 g/m³ absolute humidity or 95% relative humidity to prevent condensation. Storage limits span -30 °C to 85 °C, so the controller can be kept in storage without performance loss. The internal components tolerate temperature swings encountered during transport. When mounted in a sealed panel, the drive still depends on unobstructed airflow paths, and cabinet ventilation must maintain the specified thermal margin.
