Product Description:

Bosch Rexroth Indramat produces the DDS02.2-A100-BE33-01-FW for use in the DDS Drive Controllers series. In an automation cell, this drive controller links a motion-control CPU to the power stage that energizes an AC servo motor. This arrangement supports closed-loop velocity and position regulation directly from the cabinet. The controller is intended for cabinet-mounted servo systems that require repeatable motor response and accurate motion control during automated operation.

The control side exchanges real-time telegrams over the SERCOS interface, which allows timing and status data to travel on the same optical ring. Thermal management relies on external air from outside the control cabinet, so the cabinet must provide a clean airflow path and an exit grille to remove heated air. The power section can deliver up to 100 A of continuous output current, allowing the unit to run medium-frame motors through their full torque range without derating. Feedback processing accepts digital servo feedback and resolver feedback, so the controller can pair with motors that use high-resolution encoders or resolver transducers when high shock tolerance is needed. Its internal architecture is classified as a Digital AC Servo Drive Controller, which means switching, current regulation, and diagnostic functions are handled by onboard control electronics rather than external analog loops.

The drive is part of line 02 and build 2, and it uses Function ID version 01. These identifiers place the unit within a fixed product revision and application set. Application-specific routines reside in removable memory because firmware is ordered as a separate subitem. This arrangement allows the stored control image to be changed without replacing the main power stage, and it keeps the hardware platform available for compatible application updates.
