Product Description:

The DDS02.1-W050-DS30-01 is a digital AC servo drive controller built by Bosch Rexroth Indramat for the DDS Drive Controllers series. The unit is part of line 02 and hardware version 1. It supplies regulated three-phase power to matched motors and manages their velocity and torque loops. In industrial automation, it functions as the intermediary between a motion-control PLC and the electromechanical axis, translating command packets into accurately timed current output while monitoring motor status for closed-loop positioning and fault detection. It is intended for cabinet installation in packaging, handling, and machine-tool equipment where coordinated multi-axis movement is required. This role also lets the controller report status information back to the higher-level control so faults and motion conditions can be detected quickly.

Continuous armature demand is accommodated by a rated throughput of 50 A, so the controller can energize medium-frame servomotors without approaching saturation. Its exposed surfaces carry an IP20 protection category, so live parts must remain behind an enclosure door that meets machine safety requirements. Thermal energy is removed by air drawn from inside the control cabinet, which uses cabinet airflow to support heat dissipation through the power section. Real-time setpoints, status words, and diagnostic codes are exchanged through a SERCOS interface, giving cycle timing synchronized to the bus telegram and removing the need for vendor-specific analog wiring.

Position feedback reaches the drive through digital servo feedback, allowing the control loops to use precise timing without additional converters. The electronics operate reliably in ambient air from 0 to 45 °C, and installation is permitted at altitudes up to 1000 m before derating applies. During transport or extended shutdown, the assembly withstands temperatures from -30 to 85 °C without damage to capacitors or circuit boards. The unit carries Function ID Version 01, which identifies the parameter set used by this controller variant.
