Product Description:

The DDS02.1-W050-RA01-02-FW belongs to the DDS Drive Controllers series produced by Bosch Rexroth Indramat. It is a digital AC servo drive controller that delivers commanded current to a compatible motor, coordinating speed and torque in automated stations. Within an automation rack, the unit exchanges signals with higher-level motion hardware and evaluates motor feedback so closed-loop control remains stable during changing load conditions. It is intended for servo applications that require repeatable motion rather than simple open-loop speed control. The controller is part of line 02 and version 1 in the product range. That combination suits modular multi-axis cabinets used in factory automation cells.

An analog interface on the front card accepts ±10 V velocity commands or 4–20 mA torque references, providing compatibility with legacy machine controls. Thermal management relies on internal air cooling, so unobstructed airflow through the rack is required. The power stage can deliver a continuous 50 A output, which suits medium-frame Indramat motors in dynamic duty cycles. A housing rated to IP20 protects against accidental finger contact and blocks solid objects larger than 12 mm. Reliable operation is specified from 0 to 45 °C, which matches common temperatures inside industrial control cabinets.

Position feedback is processed through resolver feedback, allowing the controller to track rotor angle without batteries or serial encoder electronics. This feedback method supports stable motor control across a broad operating range. Installation sites can be located up to 1000 m above sea level before output derating is required. When the machine is powered down, the unit tolerates storage temperatures from -30 to +85 °C, which helps protect the electronics during transport and warehouse storage. The assigned control function is identified as Function ID 01.
