Product Description:

The DDS03.2-W050-BE09-01-FW is a digital AC servo drive controller from Bosch Rexroth Indramat in the DDS Drive Controllers series. It is intended for cabinet-mounted machinery and supplies regulated three-phase power to synchronous motors used in material handling, printing, and packaging equipment. By processing motor feedback and generating pulse-width-modulated output voltage, the controller regulates position, speed, and torque during axis movement. This type of control supports coordinated motion between multiple axes where precise timing and repeatable response are required. Because current regulation is handled inside the drive, the connected motor can respond quickly to changing load conditions and commanded motion profiles.

Communication with upper-level control systems is handled through the SERCOS interface, which supports deterministic real-time exchange of commands and status data over a fiber-optic ring. Thermal management uses internal air cooling, so the surrounding enclosure must provide airflow to carry away switching losses from the power section. The power stage is rated for 50 A, making the controller suitable for medium-frame servo motors that need steady continuous current. The drive supports digital servo feedback and resolver feedback, so it can operate with either encoder-based or resolver-based motor signal formats. This feedback flexibility allows the same controller platform to work with different compatible motor types without changing its basic operating role.

The hardware version is 2, which indicates the second design iteration of this controller. The unit carries Function ID 01 and belongs to Line 03. These codes identify the control variant used by the drive and keep the parameter structure consistent within the same device type. They distinguish this controller from other DDS units that use different feedback, interface, or control arrangements.
