Product Description:

The DDS02.1-W050-RA01-00 controller is produced by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. It is a digital AC servo drive controller used inside automated machinery to convert motion commands into precise motor currents, enabling closed-loop positioning and velocity control across multiple axes in industrial automation. This makes it suitable for coordinated motion tasks where the drive must regulate both speed and position with consistent response on packaging, handling, and similar equipment.

The drive supplies up to 50 A of rated output current, allowing mid-range axes to accelerate without exceeding the thermal limits of its power electronics. Command and diagnostic signals are exchanged through an analog interface, so a motion controller can set speed or torque by modulating voltage levels rather than using fieldbus frames. Rotor position is returned via resolver feedback, which provides absolute angle information even at standstill and resists electrical noise better than incremental encoders. Heat is removed by air from inside the control cabinet, so the cabinet cooling system must absorb the generated losses without the need for an external fan on the drive itself. The enclosure is rated IP20, which protects against accidental contact with live parts and requires installation in a clean cabinet.

To keep the internally cooled electronics within limits, the controller is intended for ambient temperatures from 0 to 45 °C, so additional cabinet airflow may be needed in warmer plant areas. For storage and transport, it tolerates temperatures from -30 to 85 °C, which helps prevent damage during periods when it is not operating. Reliable operation is permitted up to 1000 m above sea level; above that height, reduced air density requires derating. The unit is Version 1 and belongs to line 02 with function code 01, placing it within a fixed control configuration for this drive type.
