Product Description:

The DDS02.2-W050-BE25-01-FW is a digital AC servo drive built by Bosch Rexroth Indramat for the DDS Drive Controllers series. It supplies regulated three-phase power to synchronous or asynchronous motors in automated machinery. In multi-axis equipment, it acts as the power stage between the control system and the motor, converting control commands into usable output current. The unit also exchanges real-time motion data with a master control over the fieldbus so positioning, speed, and torque remain coordinated during operation. This supports positioning axes, feed systems, and general motion tasks that rely on closed-loop control.

It communicates through the SERCOS interface, allowing deterministic two-way data transfer between the drive and the PLC while keeping wiring to a single fiber loop. Thermal management relies on internal air cooling, meaning cabinet air is drawn through the heat sink rather than through external ducting. The current loop can deliver up to 50 A continuously, so the drive can support motors with moderate power demand without torque derating. An enclosure rated IP20 helps prevent accidental contact with live parts, but it is intended for dry, panel-mounted locations. Electrical and mechanical components remain functional within an ambient range of 0 – 45 °C, and the unit accepts digital servo or resolver feedback so it can work with different encoder types. This allows the same drive platform to be used with motors that have different feedback devices.

The controller maintains its performance figures up to 1000 m of installation height, so standard factory elevations do not require power derating. When taken out of service, it tolerates storage temperatures from -30 – 85 °C without internal damage to its electrical or mechanical assemblies. The unit uses release 01 and platform revision 2, which identify its control version and hardware platform. These identifiers distinguish the drive configuration used for this model.
