Product Description:

The DDS02.1-W050-DL03-01-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. Mounted beside the power supply unit inside a control cabinet, it receives low-voltage DC bus energy and modulates that power to match the instantaneous motion requirements of a single axis. It serves as the power and control stage between the supply section and a compatible servo motor. By executing current and velocity loops within microseconds, the unit maintains precise positioning for conveyor sections, pick-and-place arms, or indexing tables. In a DDS cabinet, this layout keeps the axis electronics close to the shared supply while the higher-level control system sends motion commands to the drive.

This model delivers a continuous output of 50 A, so the power section can energize medium-frame servo motors without exceeding thermal limits. Heat is removed by internal air cooling; air drawn from inside the control cabinet passes through integral channels instead of requiring an external blower. Position data returns through digital servo feedback, allowing the controller to close velocity and torque loops with high resolution during acceleration, steady travel, and stopping. Command processing uses single-axis position control, so the drive regulates one mechanical axis rather than sharing control across multiple channels. This arrangement suits modular machine layouts where each axis is assigned its own dedicated controller.

The drive is assigned Function ID 01. It is part of Line 02 and carries Version 1, which identify the product variant within the DDS range. These identifiers distinguish the unit from other DDS variants with different control functions or output levels. Classified as a Digital AC Servo Drive Controller, it contains the logic and power stage needed for closed-loop motor control while depending on a separate supply unit for DC bus power. That separation lets the cabinet supply section feed the axis controller, while the controller focuses on regulating motor current, speed, and position.
