Product Description:
The DDC01.1-K050B-DS57-00-FW is a digital intelligent servo drive manufactured by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. As a closed-loop controller, it modulates the power delivered to AC servo motors, enabling precise position, speed, and torque regulation in automated machinery and material-handling cells. The drive integrates into distributed architectures where motion tasks require deterministic coordination with other axes and sensors. Its power electronics respond to controller commands while monitoring motor feedback, allowing motion profiles to remain stable as operating loads change.
Input power is supplied through a three-phase AC mains connection, and the internal rectifier accepts line frequencies of 50/60 Hz, so the unit can connect directly to standard industrial distribution panels. The power stage delivers a continuous output of 50 A, allowing the drive to operate medium-frame motors without thermal derating under suitable installation conditions. Heat generated by the IGBTs is removed through natural convection air cooling, eliminating the need for forced airflow when ambient circulation is adequate. Command data passes through the integrated SERCOS interface, providing deterministic fiber-optic communication with motion controllers. Two analog diagnostic outputs provide real-time process variables, while digital servo feedback returns motor position data to the controller. A seven-segment status display presents operating states, and an RS-232 service port supports parameter transfer and drive diagnostics.
Overall height reaches 775 mm with the optional blower assembly and remains 635 mm without the blower assembly, allowing either enclosure profile to be accommodated. Control electronics draw logic power from a dedicated +24 V supply, while sensing circuits use a stabilized ±15 V measuring rail to isolate low-level feedback signals from power transients. Separate logic and measuring rails help prevent switching activity in the power stage from interfering with control signals. The housing dimensions must be considered together with airflow clearances, cable routing, and access to the front-mounted status and service connections. This model belongs to Series 1 and is released as Version 1.
