Product Description:

The DDS02.1-W025-DS22-02-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat and supplied as part of the DDS Drive Controllers series. Acting as the regulated power stage between a motion controller and an Indramat synchronous motor, it converts incoming electrical energy into controlled three-phase output while monitoring rotor position. It regulates motor current in real time so commanded acceleration, speed, and torque can be maintained as load conditions change. In automated assembly lines, material-handling systems, and packaging machines, the unit supports precise axis behavior so coordinated multi-axis movements remain repeatable and electrically synchronized.

Command and diagnostic data reach the controller over the SERCOS interface, a deterministic fiber-optic link that supports real-time communication for closed-loop motion control. The power section limits continuous motor current to 25 A, so cabinet ventilation must remove the resulting heat load during sustained operation. The enclosure has an IP20 rating, which means the drive must be installed inside a protective cabinet rather than exposed directly on the machine. Heat is removed by internal air cooling that circulates cabinet air across the unit and over the heat-generating components. Reliable position handling is provided through digital servo feedback, allowing the drive to process high-resolution encoder signals without analog drift. This feedback supports accurate speed regulation and stable response during direction changes, indexing, and short positioning moves. The unit operates without derating at ambient temperatures from 0–45 °C, which suits typical industrial control cabinets.

Installation altitude is limited to 1000 m because reduced air density above that height can lower cooling effectiveness. During non-operational periods, the electronics tolerate storage temperatures from -30 to 85 °C, which supports transport and warehouse storage in unconditioned spaces. This hardware build is Version 1 and belongs to Line 02 of the platform. Those identification values indicate the controller revision used for this model and help distinguish it from other builds in the series.
