Product Description:

The DDS02.1-W050-DS46-02-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It manages torque, speed, and position control between compatible Rexroth servo motors and higher-level motion controls in automated machinery. Installed in a switchgear cabinet, the unit works within a modular rack that shares a common DC bus with other inverters. Its control section helps keep multiple axes synchronized across packaging, printing, and material-handling systems.

Communication with the machine control is handled through a SERCOS interface, which transfers cyclic setpoints and diagnostic data over fiber-optic links to reduce susceptibility to electrical noise. That communication method supports deterministic data exchange for synchronized servo operation across coordinated machine sections. The power section is rated for a continuous motor phase current of 50 A, allowing the controller to operate medium-capacity servomotors under sustained load. The housing has an IP20 rating, so the unit is intended for use inside a closed electrical cabinet while protecting against accidental contact with live parts. The electronics are designed to operate between 0 to 45 °C, and the published performance data apply at installation heights up to 1000 m above sea level.

The thermal design relies on internal air cooling, which draws cabinet air across the heat sinks instead of using an external blower. Because cooling air comes from the cabinet, the panel layout should allow a clear path for heat removal during continuous duty. Motion control is supported by digital servo feedback, giving the controller precise position and speed information for stable closed-loop response. When the installation is de-energized, the unit may be stored between -30 to 85 °C without damaging internal components during transport or warehouse storage. It belongs to line 02 and is released as version 1.
