Product Description:

The DDS03.1-W050-0 is produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. It is a digital servo drive controller that regulates three-phase AC motors by linking the machine control system to the mechanical axis and matching commanded speed or torque in real time. In automated cells, it converts low-level motion commands into the precise current pulses needed for synchronous or induction motor operation. This allows the connected motor to accelerate, hold speed, and respond to load changes through closed-loop control.

Thermal management is handled with internal cabinet air, so no external ducting is required and heat is released into the cabinet airflow path. The power stage is rated for a continuous output of 50 A, allowing the drive to energize medium-frame servomotors without derating. The unit has an IP20 protection rating, which limits ingress to fingers and larger objects while remaining open to cabinet ventilation. Reliable operation is specified from 0 to 45 °C, and derating is not needed until the ambient temperature rises above that range. Installation height is limited to 1000 m above sea level, which helps maintain cooling performance and predictable semiconductor losses. Because the enclosure relies on cabinet airflow, the drive is intended for installation inside a protected electrical cabinet.

Storage is permitted from -30 to 85 °C, which helps protect solder joints and capacitors before installation. The unit is part of Line 03, and its control logic is Version 1. Classified as a digital AC servo drive controller, it can work with fieldbus or analog reference commands, supervises current loops at high frequency, and stores operating parameters in internal memory. That local parameter storage supports consistent operation after normal power cycling.
