Product Description:

The DDS02.1-W100-DS50-00-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat and part of the DDS Drive Controllers series. The unit coordinates torque, velocity, and position loops for Indramat synchronous and asynchronous servomotors, providing closed-loop regulation through integrated power electronics. In machine tools, assembly cells, and printing machinery, it links each motion axis to a higher-level PLC and converts field commands into phase-controlled motor currents. It also monitors operating conditions continuously so the drive can respond to changing load demands while protecting the motor and internal power section from excessive stress.

It exchanges real-time command and diagnostic data over the SERCOS interface, so communication can run on a single fiber-optic ring shared with other motion devices. During operation, the power stage supplies a continuous output of 100 A, which suits medium-power axes that need rapid acceleration and steady torque delivery. Heat is removed by air drawn from inside the control cabinet, so the drive uses cabinet airflow rather than external ducts or filters. The housing has an IP20 rating, and it operates in ambient temperatures from 0 – 45 °C without derating.

Installation is permitted at elevations up to 1000 m above sea level, where reduced air density can begin to affect cooling performance. The electronics can be stored between -30 – 85 °C when the unit is not in use, which supports transport and warehousing across a wide temperature span. Position verification relies on digital servo feedback, so the controller is intended for motors equipped with compatible single-turn or multi-turn encoders. The drive belongs to Line 02 and is revision 1, which keeps connector layouts, pin assignments, and diagnostic behavior consistent within this product generation.
