Product Description:

The DDS03.1-W030-RL01-00 belongs to the DDS Drive Controllers series produced by Bosch Rexroth Indramat. As a digital AC servo drive controller, it regulates current and velocity loops for synchronous and induction motors inside modular automation cabinets. By linking the drive with higher-level motion controls, it supplies regulated power that helps machine axes follow commanded moves during repetitive manufacturing cycles. It mounts on a modular backplane beside matching power supply units and exchanges diagnostic data over the system bus, which supports coordinated operation with neighboring axis modules. This layout helps keep power distribution and control wiring organized inside compact machine cabinets.

The drive employs internal air cooling, so cabinet air passes through the heat sink to remove generated losses without external blowers. Its enclosure has an IP20 rating, which supports installation in closed electrical cabinets while providing finger-safe protection. A continuous output capacity of 30 A supports medium-power servo motors without thermal derating under normal operating conditions. Command data are exchanged through a single-axis position control interface, allowing the unit to receive incremental motion targets from a higher-level controller. Rotor position returns through resolver feedback, so the drive can maintain closed-loop torque regulation at low speed and during standstill. That feedback arrangement also supports stable motor control when the axis starts, stops, or reverses direction.

Operation is permitted at ambient temperatures from 0–45 °C, and storage is permitted from -30–85 °C when the unit is de-energized. Installations above 1000 m are not recommended because thinner air reduces convective cooling. The unit carries Function ID 01 and uses hardware version 1 for compatibility with selected drive modules, power supplies, and motor data sets. Keeping the unit within those temperature and altitude limits helps avoid condensation and reduces insulation stress during storage and use.
