Product Description:

The DDS02.1-W050-DA01 is a digital drive module produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. Installed between the motion controller and an AC servo motor, it modulates power and feedback so the axis runs at the commanded velocity and torque. Its primary role in an automation cell is to convert reference values from the PLC into precise motor currents, allowing coordinated positioning, speed regulation, and dynamic braking across multi-axis assemblies. Because the drive regulates current directly at the motor interface, it can respond quickly to changing load conditions during starts, stops, and direction changes.

The drive exchanges setpoints through an analog interface, which suits legacy motion cards that output ±10 V signals. A continuous output capability of 50 A gives margin for mid-frame motors that draw high transient currents during acceleration. The enclosure has an IP20 rating, which limits direct finger contact with live parts and requires installation inside a protected cabinet. Thermal energy is removed by air from inside the control cabinet, so cabinet ventilation must keep recirculated air within the permitted ambient range of 0 to 45 °C. This cooling method is intended for enclosed electrical panels rather than exposed machine mounting, and stable airflow helps maintain consistent operation during continuous duty.

Motor position is returned to the controller through digital servo feedback, enabling fine current loops and automatic commutation without manual phasing. This feedback method supports accurate speed and position control across the motor operating range. Reliable operation is permitted up to 1000 m above sea level, which suits standard indoor industrial installations. When powered down, the hardware tolerates storage and transport temperatures from -30 to 85 °C. The drive is Version 1, and the unit is part of line 02 with function code 01.
