Product Description:

Bosch Rexroth Indramat’s DDS03.1-W050-DS40-02-FW belongs to the DDS Drive Controllers series and is supplied as a digital AC servo drive controller for cabinet installation. Within an automation cell, it receives motion commands from a higher-level PLC. It converts them into three-phase output for a connected motor and supervises current and position loops to maintain accurate velocity and torque.

The drive delivers a continuous motor supply of 50 A, which is the maximum RMS phase current the power stage can provide without derating. Communication with the master control system is handled through a SERCOS interface, enabling deterministic cyclic data exchange. Thermal management uses air from inside the control cabinet, so the surrounding enclosure must provide sufficient airflow to remove switching losses. Component ingress protection is rated at IP20, so the unit requires mounting in a closed electrical cabinet. The electronics operate reliably between 0 to 45 °C, and staying within this ambient range helps prevent overtemperature shutdown. The product is part of Line 03, and the separate FW suffix shows that the software is supplied separately.

Position verification for closed-loop control relies on digital servo feedback from the attached motor, allowing high-resolution monitoring without analog conversion stages. At installation altitudes up to 1000 m above sea level, output ratings remain unchanged, but higher sites require current reduction to offset lower air density. When the machine is idle, the assembly can be stored safely between -30 to 85 °C without affecting component lifespan. Hardware build Version 1 confirms mechanical dimensions, connector layout, and compatibility with DDS auxiliary modules, making it easier to select matching power supplies and bleeder resistors.
