Product Description:

The DDS03.1-W050-DL01-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. It forms the closed-loop power stage between an Indramat supply unit and a single servo motor, issuing regulated phase current according to numerical motion commands. By managing torque, speed, and position, the device supports precise indexing in automated machine tools, handling lines, and packaging stations. This closed-loop arrangement lets the drive respond to changing load conditions while maintaining commanded axis motion in production equipment. In system nomenclature, it belongs to Line 03, carries Function ID 01 with Function ID Version 01, and is delivered as hardware Version 1.

During operation, the drive can supply a continuous output of 50 A, which is the maximum motor phase current the power electronics can deliver without derating. Internal heat is removed by air from inside the control cabinet, so the unit must be installed where enclosure ventilation is sufficient. Electrical safety relies on the IP20 housing, which helps prevent accidental contact with energized parts but does not seal against dust or moisture. Motion instructions are handled through single-axis position control, allowing the position loop to be closed internally. Accurate rotor angle information is supplied through digital servo feedback, enabling stable regulation during rapid acceleration and deceleration cycles. The controller processes command and feedback data in the same unit, which helps maintain position accuracy during speed changes and load transitions.

The controller supports continuous operation between 0 – 45 °C in a normally conditioned cabinet. Rated output remains valid up to 1000 m elevation, and derating is required above that height. During shipping or storage, the electronics withstand temperatures from -30 to +85 °C. These temperature limits apply when the unit is powered down during transport or warehouse storage. The drive is supplied with firmware ordered as a separate subitem, so the required motion functions can be matched to the application.
