Product Description:

The DDS03.1-W050-DS01-00 is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. It converts power from a regulated DC bus into controlled motor current for servo operation, allowing compatible motors to respond accurately to speed, torque, and position commands. In automated assembly cells, handling robots, and material-processing equipment, that control supports repeatable motion during indexing, transfer, and positioning cycles. Its modular format suits multi-axis cabinets where several drives share supply and communication infrastructure. The unit belongs to Line 03 in the DDS platform and carries Function ID 01 for this controller configuration.

This controller provides a continuous output of 50 A, allowing sustained motor current within its thermal operating range during normal duty. The enclosure has an IP20 rating, which protects against finger contact and solid objects larger than 12.5 mm while leaving ventilation openings available for cooling airflow. Real-time command and diagnostic data are exchanged through the SERCOS interface, allowing deterministic communication when several axes share one fiber-optic ring. Component temperature is managed by internal air cooling, so cabinet air moves across the heat sink without external ducting. Reliable operation is intended for an ambient range of 0 to 45 °C, which suits most indoor industrial installations.

The drive can operate at elevations up to 1000 m without derating. When powered down, it can be stored at temperatures from −30 to 85 °C, allowing transport and warehousing in non-climate-controlled conditions. Motor position data return through digital servo feedback, which supports closed-loop control and lets the controller correct speed and position errors during motion. This feedback arrangement lets the unit process encoder information directly from compatible motors, which helps maintain stable axis behavior during acceleration, deceleration, and low-speed holding. The unit is Version 1, matching the assigned product revision for this model and its related rack modules.
