Product Description:

The DDS02.1-W150-DS56-00-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. Mounted inside an automation cabinet, it converts the DC bus energy from the supply module into precise three-phase outputs that command matched servomotors used on packaging lines, handling robots, and machining centers. Through real-time exchange with higher-level motion processors, the unit regulates torque and position, acting as the active link between the power stage and the machine mechanics.

The power section can deliver up to 150 A of continuous phase current, giving ample headroom for axes that see large acceleration demands. Its housing meets IP20, so finger protection is provided, but the cabinet must provide the required sealing. Command and diagnostic data move over the fiber-optic SERCOS interface, supporting deterministic communication across multiple drives on a single loop. Thermal losses are removed by air from inside the control cabinet; therefore, enclosure airflow must be managed to keep internal electronics within the permitted range. Reliable operation is maintained when the ambient remains between 0 to 45 °C, matching typical plant-floor conditions without additional cooling hardware.

The controller can be installed at elevations up to 1000 m without derating, allowing placement in most factory mezzanines and multistory conveyor towers. When powered down, components tolerate a storage range of -30 to 85 °C, which simplifies storage in unheated facilities. Motor transducers connect through the integrated digital servo feedback channel, enabling high-resolution position loops without external converters. Application-specific functions are supplied as a separate subitem, allowing the drive configuration to be matched to the intended use.
