Product Description:

The DDS2.1-W050-DS03-00 is a servo drive controller manufactured by Bosch Rexroth Indramat within the DDS Drive Controllers series. Designed for integration into multi-axis automation systems, the unit regulates three-phase AC servo motors by modulating the current and voltage supplied through its DC bus. In industrial cells, it functions as the intermediary between the host motion controller and the connected motor, executing torque and speed commands in real time while supporting coordinated axis movement across the machine.

Motion commands arrive over the SERCOS fiber-optic interface and are reconciled with incremental data from its digital servo feedback channel. The internal power section operates from a DC link at 300 VDC. Continuous output current is limited to 40 A, while its rated and short-term peak current both reach 50 A for acceleration bursts. Protection against accidental contact is provided by the IP20 housing, which is suited for installation inside an electrical enclosure. Mechanical retention of supply wiring is set at 3 Nm on the DC bus terminals and 5 Nm on the mains power studs, helping the connections remain secure under vibration.

Thermal management relies on internal air cooling, allowing full output within an ambient range of 0 – 45 °C. A service port using the RS-232C protocol is present for setup changes and diagnostic queries, giving direct access to drive data without using the main motion network. Installation is permitted up to 1000 m above sea level without derating, and operation can resume after storage between −30 °C and 85 °C. The module stands 390 mm high, 355 mm wide, and 325 mm deep, with a mass of 7.5 kg, so the cabinet must allow adequate mounting space and structural support. Its 24 VDC brake supply output powers holding brakes on connected motors during standby.
