Product Description:

The DDS02.1-A200-DS68-00-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. It operates as a servo amplifier that links a DC supply module to synchronous or induction motors, converting command signals into regulated three-phase output. In industrial automation, this unit provides accurate velocity and torque regulation for axes used in machining centers, packaging equipment, and automated handling cells. Because it can work with synchronous or induction motors, it suits a wide range of machine axes that require controlled motion under changing load conditions. This supports repeatable motion during acceleration, deceleration, and steady running.

Command data enter the controller through the SERCOS interface, which provides deterministic timing for coordinated multi-axis motion. The power stage can deliver a continuous phase current of 200 A, so busbar sizing and overcurrent protection must match the load. Thermal energy leaves the heat sink by external air cooling, meaning filtered ambient air from outside the cabinet is directed across the fins. Rotor position is returned through digital servo feedback, allowing the control loops to calculate torque without analog drift. This feedback path supports closed-loop speed and position control while maintaining a consistent response during changing operating conditions. Using outside air for cooling also moves heat away from the cabinet interior instead of recirculating warm air around nearby modules.

Within the modular drive family, the unit is part of Line 02 and is Version 1. The product category is Digital AC Servo Drive Controller, which confirms operation with three-phase power supplied through a shared DC bus. Motion commands travel over a fiber-optic cable, which electrically isolates the control electronics while supporting high-speed data exchange. The isolated communication path also reduces the effect of electrical noise between the controller and the higher-level motion system. This arrangement suits modular drive systems where multiple axes must exchange synchronized command and status data through a common control platform.
