Product Description:

The DDC01.1-K150A-DS03-02-FW is a digital intelligent servo drive manufactured by Bosch Rexroth Indramat within the DDC Digital Intelligent Servo Drives series. It is intended for closed-loop control of synchronous motors in automated machinery, where the drive converts incoming power into regulated motor current for accurate motion. In machine tools, transfer systems, and handling axes, the unit supervises power conversion, axis regulation, and motion monitoring in one enclosure. This arrangement supports stable speed control, repeatable positioning, and coordinated response to changing load conditions.

The command module uses the SERCOS interface, allowing deterministic fiber-optic communication with higher-level motion control. A continuous output of 150 A supports demanding servo duty and gives the power stage the current needed for sustained operation. Heat is removed by natural convection, so the drive can operate without added forced-air hardware. Operating states and fault codes appear on an alphanumeric display, making status information easy to read at the unit. During rapid deceleration, an integral DC bus dynamic brake dissipates regenerated energy inside the drive instead of relying on a separate external resistor.

An enclosure rated at IP65 protects the electronics from dust and low-pressure water jets while preserving the thermal path of the housing. The compact housing mounts directly on the machine by means of a direct feeder mount, which helps reduce cabinet depth and shortens cable routes between the drive and motor. Position data is returned through digital servo feedback, allowing high-resolution closed-loop control during speed and position changes. Integrated inrush current limiting and an onboard mains contactor reduce the need for external switching components, and the noise emission category matches the 100–200 A class. The unit uses function code 03 and is built as series 1, version 1.
