Product Description:

The DDS03.1-W050-DL20-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat in the DDS Drive Controllers series. The unit interfaces with a servo motor to regulate velocity and torque in automated machinery, serving as the axis-level control element between high-level motion commands and the mechanical load. In a machine-control architecture, it receives motion commands from the higher-level system and converts them into regulated motor action at the axis. It is intended for installation inside a control cabinet, where it supports closed-loop motion on production lines and similar automated equipment.

The communication interface supports single-axis position control with rapid updates. The drive delivers a continuous output of 50 A, providing capacity for medium-power motors during sustained operation. An IP20 protection rating means the unit is guarded against accidental finger contact, so enclosure mounting remains necessary. Thermal management relies on air from inside the control cabinet, which means the cabinet must provide forced ventilation and stable internal airflow. Because cooling air is drawn from the cabinet interior, the heat produced by nearby components can affect the drive's operating temperature. The permissible ambient operating range is 0 to 45 °C, allowing full-load service within that temperature band. Control loop feedback is handled through digital servo feedback, which transfers position and velocity data with good resistance to electrical noise.

The controller belongs to Line 03 and is issued as Version 1. These identifiers indicate the product generation used for this drive type. Altitude capability up to 1000 m means no output reduction is required at most plant locations. When de-energized, the electronics tolerate a storage range of -30 to +85 °C, so warehouse and transport conditions well outside the operating range do not damage internal components.
