Product Description:

The DDS03.1-W030-DA02-01-FW is a drive controller from Bosch Rexroth Indramat in the DDS Drive Controllers series. It installs on a common DC bus rail inside the machine's electrical cabinet and connects to adjacent DDS modules through backplane connectors. Acting as the power stage for a single axis, the unit converts the shared bus voltage into three-phase output that follows the command profile generated by the machine controller. This regulation supports precise speed, torque, and positioning functions in automated production lines, packaging systems, and material-handling cells. The cabinet-mounted format suits multi-axis equipment where several motion components are grouped in one enclosure.

It supplies a rated output of 30 A, so the connected power stage can deliver full torque to medium-frame synchronous motors without current derating. Command and diagnostic signals enter the unit through an analog interface, allowing legacy PLCs to issue speed, torque, or position references without network adapters. Thermal management relies on internal cabinet air cooling, so the drive releases warm air into the cabinet exhaust path and does not require a separate fan shroud. Rotor position information is returned over digital servo feedback, providing high-resolution commutation and immediate fault indication if encoder data is lost. Control software is not included with the base unit and must be ordered as a separate subitem.

The controller belongs to Line 03 and carries Function ID version 01. The underlying electronics correspond to hardware revision 1. The unit is a digital AC servo drive controller and is used in multi-axis racks where several DDS drives share a common DC bus. Its modular form allows it to sit beside matching DDS units in the same rack structure. This arrangement keeps power conversion close to the connected axis while leaving higher-level command generation to the external machine controller.
