Product Description:

The DDS03.1-W030-RA02-01 is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. Installed inside electrical cabinets, the unit links a power supply module with a motor to execute closed-loop motion commands from a higher-level PLC for coordinated motion tasks in automated machinery. Within an automation cell, it converts reference values into phase-modulated currents so that a servomotor maintains commanded torque, speed, or position during changing load conditions. Its rack-mount format preserves consistent wiring geometry across machine frames and fits cleanly into multi-axis cabinet layouts where consistent spacing is needed between neighboring modules.

This controller exchanges setpoints through an analog interface, allowing ±10 V velocity or torque commands to be processed without fieldbus hardware. Feedback arrives from the motor via integrated resolver feedback, so shaft position is detected at standstill and under high shock conditions. A continuous output capacity of 30 A lets the drive energize medium-frame motors while keeping current headroom for acceleration and short-term load changes. Heat is removed by internal air cooling, so cabinet airflow passes directly over the heat sink and no external blower or liquid loop is required. The unit belongs to Line 03, which groups devices with the same physical dimensions and connector layout.

The function ID is fixed at 01, so the controller uses the parameter structure assigned to that function set. The unit is Version 1, which identifies this product revision. It is part of the DDS Drive Controllers series, and it connects to matching supply modules through daisy-chain DC bus bars to reduce cabinet wiring. This arrangement keeps interconnections short inside the cabinet and supports orderly routing between adjacent power and control modules.
