Product Description:

The DDC01.1-K050A-DL28-00 is a compact digital intelligent servo drive manufactured by Bosch Rexroth Indramat. It is part of the DDC Digital Intelligent Servo Drives series and is identified as Series 1, Version 1. Designed to control synchronous servo motors in automated machinery, the unit combines motion control, power conversion, and I/O supervision in one enclosure. By embedding application logic inside the drive, the unit reduces the load on an external controller and simplifies cabinet wiring. This arrangement allows the drive to handle axis-level control tasks directly at the machine.

The drive uses a three-phase input of 3 x AC 230 V and can deliver up to 50 A of motor current, supporting high-torque acceleration on medium-power axes. An enclosure rating of IP65 permits direct mounting outside control cabinets while helping keep dust and water jets away from the electronics. Its analog monitor channel operates over ±10 V and supports loads up to 4 mA for process feedback signals. Internally, the controller stores up to 3000 program blocks, allowing multipart motion sequences to run without an external PLC. Control circuitry is powered by a 24 V DC service line that draws 150 mA, and the logic exchanges position data with the motor through digital servo feedback for closed-loop accuracy.

Heat is removed through natural convection air cooling, so the unit does not require a fan. Position generation is handled by the built-in single-axis positioning command module, and the drive-to-motor connection can extend to 75 m when the specified power cable size is used. The service rail is rated at 24 V DC and also supplies the ready contact, which can switch 1 A. The power-on relay carries 6 A at 230 V AC for mains interfacing, and noise emission remains within the standard 100 A to 200 A class. These operating details support use on automated axes that need compact drive-side control.
