Product Description:

The DDS03.1-W030-RL01-01-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. It links higher-level PLC commands to the power stage that energizes a servomotor, allowing precise electronic gearing, speed regulation, and coordinated motion in automated material-handling or machine-tool equipment. By converting logic-level setpoints into controlled three-phase output, the unit provides closed-loop regulation for a single mechanical axis in industrial automation. This arrangement helps the controller correct load changes quickly while maintaining commanded motion on one axis.

The control architecture supports single-axis position control, so one drive governs one mechanical load without shared current paths. A continuous output of 30 A is the maximum RMS current the power section can deliver to the motor windings during normal duty cycles. The drive housing is rated IP20, so live parts are finger-safe but the device must be installed in a protected electrical enclosure. Cooling relies on internal air cooling. Cabinet airflow passes directly across the heat sink, so the panel must provide enough air movement to dissipate switching losses. Ambient operation is permitted between 0–45 °C, which keeps the unit within its intended thermal range.

Motor feedback is processed through resolver feedback, allowing the controller to track rotor angle and speed during operation. Altitude capability reaches 1000 m above sea level, after which current derating or additional cooling may be required. When powered down, the unit tolerates storage temperatures of −30–85 °C, which supports transport and storage in non-climate-controlled spaces. The unit uses Function ID 01 with hardware Version 1, and it belongs to Line 03 in the DDS platform.
