Product Description:

The DDS02.2-W050-BE98-01-FW is a drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. It serves as the electrical interface between the power bus and compatible synchronous or induction motors used in automated machinery. The unit accepts motion commands from a digital network, converts available bus power into controlled three-phase output, and adjusts current delivery as load conditions change. This allows a machine axis to maintain commanded speed and torque during indexing, transfer, and other coordinated movements.

The controller can supply a continuous phase current of 50 A, which gives medium-frame motors enough current for steady production duty and brisk acceleration. Communication with the control system occurs over a SERCOS interface, providing deterministic fiber-optic telegrams for synchronized multi-axis operation and predictable command timing. An enclosure rating of IP20 means the unit is intended for use inside a closed control cabinet where contact protection is required but direct liquid exposure is not expected. The permitted ambient range is 0 – 45 °C during operation, and the installation altitude can reach 1000 m before additional cooling or power reduction may be needed.

Heat generated by the output stage is removed through internal air drawn from within the cabinet, so unobstructed airflow around the drive helps stabilize operating temperature. The electronics tolerate storage temperatures from -30 – 85 °C when the unit is not energized, which supports transport and warehousing under wide climate conditions. Built-in support for Digital servo feedback and Resolver feedback allows the same controller platform to work with either high-resolution encoder systems or more rugged analog feedback devices. That flexibility makes the drive suitable for precision positioning axes as well as applications that favor simple, durable motor feedback.
