Product Description:
The DDS03.1-W050-RS01-01 is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. In an automation cell, it forms the power stage between a supply module and a synchronous or asynchronous servo motor, modulating current and speed commands from the machine control. Its configuration targets multi-axis systems that require coordinated motion between several driven axes. When mounted in a shared backplane, it links to adjacent modules to create a scalable drive package for packaging equipment, printing lines, or material-handling gantries. This layout helps centralize drive functions inside the control cabinet while keeping axis response tightly coordinated across the machine.
The drive delivers a continuous output of 50 A, giving it headroom to propel medium-frame motors through acceleration phases without clipping. Command and diagnostic data pass over the optical SERCOS interface, so the controller can exchange cyclic information with the higher-level motion system. Thermal management relies on internal cabinet air, and fans circulate that airflow through the controller's heat-sink fins without external ducts. The housing meets IP20, so fingers and small tools are shielded while ventilation slots remain open for cooling. For position loops, the unit interprets resolver feedback, converting analog sine-cosine signals into rotor angle information that remains stable at high shaft speeds and in electrically noisy environments.
This controller is assigned Function ID 01 and belongs to Line 03 with version 1. It operates in ambient temperatures between 0–45 °C and maintains full current capacity up to an installation height of 1000 m above sea level. During plant shutdowns or transport, the electronics can be stored safely in a range of –30 to 85 °C. The unit is intended for standard indoor cabinet use where those operating and storage temperatures can be maintained. Stable cabinet conditions help preserve cooling performance during continuous duty.
