Product Description:

The DDS02.1-W150-DS68-00-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat within the DDS Drive Controllers series. It regulates servo motor torque and velocity in multi-axis industrial machinery, using closed-loop feedback to align commanded motion with actual shaft position. This allows coordinated axes to respond accurately to commands from a PLC or motion controller during production. In a multi-axis system, the unit helps keep acceleration, speed, and stopping behavior consistent across linked machine sections.

The unit exchanges real-time setpoints and status over a SERCOS interface, allowing deterministic fiber-optic communication with other drives and a central controller. Thermal management relies on internal air cooling, so cabinet airflow must remove heat from the power electronics without external ducting. Its power stage is rated for 150 A of continuous output current, which suits large servo motors with high current demand. The enclosure has a protection rating of IP20, so the drive must be installed inside a cabinet that protects it from conductive debris and accidental contact. Reliable operation is permitted at ambient temperatures from 0 to 45 °C, which matches typical industrial control cabinet conditions.

Installation elevation is limited to 1000 m, because thinner air above that height reduces cooling effectiveness. Rotor position is monitored through digital servo feedback, allowing the current and velocity loops to maintain accurate control during changing loads. This feedback lets the controller compare commanded and actual motor values in real time for stable axis response. Long-term storage is permitted from -30 to 85 °C, which helps protect the electronics during transport or inactive periods. The unit is part of line 02 and is built as Version 1, identifying the product revision used for this drive.
