Product Description:

The DDS02.1-W050-DS45-00-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. It converts three-phase supply power into regulated output for synchronous servo motors and carries out velocity, torque, and positioning commands from higher-level motion controllers. In automated equipment, it serves as the power stage between the control system and the mechanical axis, allowing packaging lines, printing systems, and assembly stations to run with accurate response and repeatable motion under changing load conditions.

Communication with the host automation layer runs over the SERCOS interface, allowing deterministic data exchange for setpoints, status bits, and diagnostics. Heat generated by the power electronics is removed through internal air cooling, which circulates cabinet air across the drive's heat sink without external ducting. The current stage is rated for a continuous output of 50 A, giving the controller suitable capacity for mid-power servo axes that require steady torque delivery. The IP20 enclosure helps protect against accidental contact, so the unit must be installed inside a control cabinet. Reliable operation is maintained across 0 to 45 °C, and the unit belongs to line 02 of the product family.

Installation heights up to 1000 m above sea level are permitted without derating. Rotor position is resolved through digital servo feedback, helping the drive maintain closed-loop precision during speed and position control. This arrangement supports consistent tracking during normal machine cycles. The storage range of -30 to 85 °C allows the unit to withstand common transport and warehouse conditions while powered down. The delivered hardware is Version 1, indicating the revision used for this drive type.
