DDS03.1-W050-DS29-01

The DDS03.1-W050-DS29-01 digital AC servo drive controller is produced by Bosch Rexroth Indramat for its DDS Drive Controllers series. Within an automation cabinet it serves as the power-stage that interprets motion commands and delivers controlled current to matched servo motors, enabling precise positioning and speed regulation on packaging, printing, or material-handling lines.

This drive can supply up to 50 A of continuous output current, a value that defines the maximum motor phase current it can regulate without thermal derating. A fiber-optic SERCOS interface forms the real-time communication link to the motion controller, allowing deterministic command and feedback cycles. Temperature management is handled through internal air cooling; cabinet air passes across the heat sink, so overall enclosure airflow must be planned accordingly. Position data from the motor is returned via Digital servo feedback, which provides high-resolution encoder information for tight current and velocity loops. Hardware classification under Line 03 places the unit in the third power-range segment of the DDS platform and dictates the appropriate supply module and downstream cabling dimensions.

Firmware compatibility is locked by Function ID Version 01, ensuring that control algorithms and parameter structures remain constant across replacements. Hardware Version 1 identifies the initial mechanical design revision and keeps spare-parts selection unambiguous. Within the broader Bosch Rexroth Indramat modular system, the controller mates directly with other components of the DDS Drive Controllers series to build multi-axis racks sharing a common DC bus, which minimizes wiring and simplifies energy distribution.
