Product Description:

The DDS02.1-W150-DS53-00-FW is a drive controller built by Bosch Rexroth Indramat and supplied in the DDS Drive Controllers series. Designed for cabinet-mounted motion systems, the unit regulates torque, speed, and position of connected servo motors in automated machinery. It acts as the power stage between motion commands from a PLC and the mechanical load, so commanded axis movement can be translated into controlled motor output. Because the controller is mounted in the cabinet rather than on the motor, it can be combined with centralized power distribution and protected from direct exposure on the machine.

The controller exchanges cyclic setpoints and feedback over the SERCOS interface, allowing deterministic fiber-optic communication with master drives. A continuous phase current of 150 A indicates the maximum sinusoidal current the power stage can supply without thermal derating, which supports high-demand servo applications during sustained acceleration. Cooling is handled by air from inside the control cabinet, with airflow pulled through the heat sink to remove losses while the enclosure remains sealed. Rotor position signals are processed through digital servo feedback, supporting high-resolution encoders and stable velocity control without separate signal converters. That feedback path allows the drive to monitor rotor angle and speed continuously during rapid changes in load.

Within the product naming structure, the controller belongs to Line 02 and is released as Version 1. It is classified as a Digital AC Servo Drive Controller, which means it is intended for digitally commanded servo operation in three-phase systems. The unit is used in modular drive racks with a common DC link, allowing several axes to draw energy from the same bus while each inverter remains individually fused. Its placement in the DDS platform also matches the mounting and bus geometry used by other modules in the same rack, which helps maintain an orderly layout in multi-axis assemblies.
