Product Description:

The DDS02.1-W050-DS12-01 is a digital AC servo drive controller from Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. Within an automated production cell, this module links a motion control system to a servo motor and regulates torque and speed according to program commands. The drive forms the electrical interface between higher-level motion commands and the motor response at the machine axis. By converting three-phase supply power into a controlled output waveform, it allows precise axis positioning and repeatable cycle times in packaging machines, printing presses, and material-handling gantries.

Communication occurs over the SERCOS interface, a fiber-optic bus that carries cyclic setpoints and status data in deterministic time slots. At its continuous rating, the drive can supply 50 A of output current, which is the steady sine-wave current available to the connected motor windings during normal operation. Thermal energy is removed by internal cabinet air cooling, so the unit relies on the cabinet forced-air path instead of its own fan. Motor position and velocity are returned through digital servo feedback, enabling a closed control loop with high resolution. This arrangement helps the control loop maintain stable speed and position response during dynamic motion. The unit is a Digital AC Servo Drive Controller, so it produces three-phase output with selectable PWM frequency for synchronous or induction motors.

The unit is part of Line 02, which places it in the second mechanical generation with updated power-stage components. A dedicated parameter set is assigned to Function ID Version 01, so key operating ranges stay matched to this control layout. The base release is Version 1. The control architecture uses fixed firmware for consistent operation across identical axes.
