Product Description:

The DDS03.1-W030-RS18-00 is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It governs compatible servo motors by modulating three-phase output power in response to commands from a higher-level motion system. This arrangement supports precise velocity and torque regulation in automated machinery and allows the drive to serve as the control link between the motion platform and the motor.

This controller delivers a continuous output of 30 A, so the connected inverter and cabling must be sized for that current during steady operation. Its housing carries an IP20 protection rating, which provides finger-safe access but requires installation inside an enclosure for protection from dust and moisture. Thermal energy is removed by internal air cooling, so cabinet airflow directly affects the drive’s operating duty. Command and diagnostic data travel over the SERCOS interface, providing deterministic fiber-optic communication with axis controllers and helping simplify multi-drive wiring. Position and speed loops are closed using resolver feedback, and this sensor supplies rotor position information that supports smooth low-speed motion and reliable restart behavior after a mains interruption.

The permissible ambient temperature range is 0 to 45 °C, so additional cooling is required if cabinet temperature rises above that limit during continuous high-load operation. When powered down, the unit can be stored from -30 to 85 °C, which allows shipment or warehouse storage without active conditioning. Installations are approved up to 1000 m above sea level, because higher elevation reduces air density and lowers cooling performance. The unit is Version 1 and belongs to line 03 in the DDS platform. These identifiers distinguish this build within the product range and help match it to the correct application setup.
