Product Description:

The DDS02.2-W015-BE43-02-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat within the DDS Drive Controllers series. It bridges a machine’s central motion processor and the servomotor it energizes, modulating voltage and frequency so commanded torque and speed are met in real time. Used with Rexroth modular power supplies, the unit mounts in a cabinet rack where multiple axes can share a common DC bus, conserving panel space and simplifying wiring for automated assembly lines, packaging equipment, and pick-and-place stations.

The drive communicates with the control system through the SERCOS interface, enabling deterministic fiber-optic data exchange for sub-millisecond cycle times. Components are cooled by air from inside the control cabinet, so adequate enclosure airflow is required to avoid thermal derating. Under rated conditions, the power stage supplies 15 A of continuous current, a key parameter for selecting compatible motors and conductors. The housing carries an IP20 protection rating, blocking accidental finger contact yet providing no liquid seal, so the controller must stay in a closed electrical cabinet. Reliable operation is specified for ambient temperatures from 0 to 45 °C; operation outside this range may cause automatic current limiting or shutdown.

Feedback options include digital servo feedback and resolver feedback, allowing the same drive to run motors equipped with high-resolution encoders or rugged resolvers without extra interface cards. Installation elevation is limited to 1000 m; higher altitudes reduce air density and compromise the internal cooling path. During transport or warehousing, the electronics tolerate storage temperatures of -30 to 85 °C, which allows storage in unconditioned shipping containers. The drive uses separate firmware, so the required software revision can be selected for the application.
