Product Description:

The DDS02.1-W050-RL20-01-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat and supplied within the DDS Drive Controllers series. It regulates torque, speed, and position for synchronous or induction servomotors used in automated machinery. Installed in a control cabinet, the unit serves as the link between the motion control system and the motor by converting command signals into regulated three-phase output and monitoring feedback for closed-loop accuracy. This arrangement helps the axis maintain stable motion during changing load conditions in packaging, handling, and other automated equipment.

Command processing relies on single-axis position control, allowing one mechanical axis to run with internal profiling and reduced control overhead. During continuous operation, the drive can deliver up to 50 A of phase current, supporting applications that need sustained motor output without immediate derating. Heat from the power semiconductors is removed by internal air cooling, so the cabinet must provide a clear airflow path around the unit. The housing is rated IP20, which provides finger-safe protection but still requires enclosure-level protection against dust and moisture. For motor feedback, the controller uses resolver feedback to read coarse and fine angle signals for commutation and speed control, including applications that involve vibration.

The drive operates in ambient temperatures from 0 to 45 °C, allowing it to work alongside other heat-producing modules in a standard control cabinet. For transport or storage, it tolerates temperatures from -30 to 85 °C without damage to the electronics when the unit is not operating. Installation is supported up to 1000 m above sea level, where normal air density is still available for the cooling path. The parameter structure and diagnostics correspond to Function ID version 01, which identifies the control-function revision used by this model.
