Product Description:

The DDS03.1-W030-DA11-01-FW is a drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It links motion commands from higher-level control systems to an attached servomotor. The controller supplies regulated current and voltage so automated axes can reach commanded positions and speeds in industrial machinery. The unit is used where a machine must translate low-level reference commands into controlled electrical output for the motor. By regulating the motor in real time, it supports smooth acceleration, steady running speed, and repeatable stopping points.

This controller delivers a continuous output of 30 A, which is the maximum RMS phase current the power stage can supply without derating. Command signals reach the device through an analog interface, allowing external control circuits to send reference values to the internal electronics. Heat from the power section is removed by internal air cooling, so the cabinet must provide adequate airflow for stable operation. This cooling method uses air already present inside the enclosure, so spacing and ventilation around the module remain important during installation. Motor position is returned through digital servo feedback, allowing closed-loop commutation, fast correction of deviation, and reliable speed regulation. The unit is part of Line 03, which shares mechanical dimensions and connector layouts with other modules from the same generation.

The controller incorporates Function ID Version 01, which is used as a fixed product identifier within the design. The hardware is issued in Version 1, indicating the revision level of the unit. These identifiers distinguish this controller from other variants in the DDS product line. They also separate this version from other control and power combinations in the same platform.
