Product Description:

The DDS03.1-W030-DS56-00-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. Designed for multi-axis machinery, it supplies regulated three-phase power to attached motors and executes torque, speed, and position loops demanded by a higher-level motion system. Integrating the drive in a common backplane helps reduce wiring while retaining modularity. This type of controller is commonly used in packaging, assembly, and transfer systems that need accurate coordination across several servo axes. Its closed-loop operation helps connected motors respond consistently during acceleration, deceleration, and holding moves.

Communication with the supervisory control layer is carried out through the SERCOS interface, which provides deterministic fiber-optic messaging for real-time parameter updates. The power stage delivers a continuous output of 30 A, allowing the drive to support compatible motor loads without thermal derating. Heat produced by the IGBTs is removed by internal air cooling, meaning cabinet air is drawn across the heat sink rather than relying on an external blower. The enclosure has an IP20 protection category, so the unit must be installed inside a closed panel to prevent exposure to dust and accidental contact. Safe operation is maintained within an ambient range of 0 to 45 °C, allowing placement alongside other control electronics without additional conditioning.

Position data from the connected motor is returned through digital servo feedback, allowing the drive to close loops without analog converters. The controller belongs to product line 03 and is released as Version 1. Continuous ratings remain valid up to 1000 m above sea level, and reduced cooling air density above that altitude requires current derating. When the machine is idle, the unit tolerates storage temperatures from -30 to 85 °C, which helps protect control panels during unconditioned storage or transport. This feedback and operating range make the controller suitable for industrial systems that need stable motion control under normal cabinet installation conditions.
