Product Description:

The DDS02.1-W150-DS50-01-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. Designed for multi-axis automation, it converts command signals from higher-level motion platforms into regulated current and voltage for matched servo motors. The compact module slides into a standard 4-slot rack and shares a common DC bus with adjacent DDS supplies, enabling coordinated axis control across packaging lines, printing machines, and material-handling stations. This rack-based layout supports dense axis grouping and keeps the drive section integrated with the rest of the motion system.

It communicates with the supervising CNC or PLC over the SERCOS interface, allowing deterministic cyclic data exchange. The power stage can supply up to 150 A of continuous output current, enabling it to drive large synchronous or induction servos without derating. Thermal management relies on air drawn from inside the control cabinet, so cabinet airflow must remove switching losses from the heat sink and surrounding electronics. Rotor position and velocity are closed-loop through digital servo feedback, which the controller reads in real time for high-bandwidth compensation. The controller uses Function ID Version 01, which fixes the parameter structure used by this drive type.

The product is part of Line 02, and the hardware is listed as Version 1. Those identifiers correspond to the mechanical layout and connector arrangement used by this unit. Application-specific code is not bundled, so a separate firmware subitem is required before the controller can be matched to the selected motor type. When the appropriate software is loaded, the unit operates as a Digital AC Servo Drive Controller and converts network motion commands into controlled phase current for the motor. This allows the drive to support closed-loop speed and position control in demanding automated machinery.
