Product Description:

The DDC01.1-K050A-DA07-00/S001 belongs to the DDC Digital Intelligent Servo Drives series produced by Bosch Rexroth Indramat. It serves as the power stage of a closed-loop axis, taking velocity or torque references from an analog motion controller and driving a matched synchronous motor through three-phase outputs. In automated assembly cells, pick-and-place units, and machining centers, the drive regulates motor current and position to support accurate, repeatable motion under varying mechanical loads. Because the control loop continuously compares commanded and actual motion, it can correct for changing load conditions during acceleration, deceleration, and steady-speed operation.

The unit is designed for a three-phase mains supply and accepts an input of 3 x AC 220/230 V at 50/60 Hz. Its continuous output capability reaches 50 A, so drive sizing can match medium-power axes without oversizing upstream protection. A command module with an analog interface receives ±10 V setpoints, while digital servo feedback from the motor sends precise rotor position data to the internal regulator. This arrangement supports analog control systems that use external motion controllers instead of a networked fieldbus. DC-bus monitoring trips the inverter at 475 V and blocks enabling below 200 V, which helps protect components during supply surges or brownouts. Cooling uses natural convection air cooling, eliminating fans and the maintenance they introduce, but it requires unobstructed cabinet airflow. The noise emission is rated as standard. The unit uses function code 07, Series 1, and Version 1.

A sealed housing rated IP65 allows installation on the machine frame, even in areas exposed to dust or low-pressure water jets. The enclosure has a height of 775 mm and a width of 275 mm, while the depth is 298 mm, so it fits common cabinet and machine layouts without taking excessive front space. The analog interface occupies a dedicated front slot, and the DC-bus terminals remain accessible from the top edge, allowing straightforward routing to adjacent regenerative modules or braking resistors without crossing signal conductors. The front-facing interface area also keeps signal connections reachable after installation, which helps preserve orderly cable routing in compact assemblies.
