Product Description:
The DDS03.1-W050-RL01-01-FW is a drive controller produced by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. As a single-axis unit, it sits between a compatible supply module and servo motor to regulate torque, speed, and position in automated equipment. It converts available drive-system power into regulated motor current so the commanded motion profile can be followed with consistent response. This arrangement supports coordinated motion in pick-and-place systems, printing lines, and material-handling axes where steady closed-loop control is required during acceleration, deceleration, and holding periods. The controller is intended for cabinet-based installations that use a modular drive layout and a dedicated motor feedback channel.
The controller can deliver a continuous output of 50 A, giving it enough current capacity for medium-frame servo applications without overstating its thermal limits. Command data is handled through single-axis position control, so the motion section can send setpoints directly to the drive for precise axis response. Motor angle is returned by resolver feedback, which closes the loop without requiring a digital encoder on the motor. Cooling is provided by internal cabinet air, meaning the unit uses air already circulating inside the enclosure rather than a separate external duct. The product is part of Line 03, which places it within a consistent design line for this controller platform.
The unit carries Function ID 01, which corresponds to the standard control function used for this drive type. Its hardware revision is Version 1, identifying the build level used for the controller. These identifiers distinguish the control function and revision level used by the unit without repeating information already stated elsewhere. In practical use, the controller depends on matched command processing, motor feedback, and cabinet airflow so that axis response remains stable during normal operation. That combination suits applications that require repeatable starts, stops, and short positioning moves across a single controlled axis.
