Product Description:

The DDC01.1-K050B-DS47-00-FW is a digital intelligent servo drive produced by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. It converts three-phase mains power into controlled current for synchronous or induction motors while exchanging real-time commands with higher-level motion controllers. In automated machines, the drive forms the power and regulation core of axes that demand accurate velocity and position control in packaging, material-handling, and machining stations.

The power stage accepts a three-phase AC input at 230 V and supplies up to 50 A of continuous phase current. An internal monitor trips above 475 V to protect the DC link. The control electronics use 24 V DC at 150 mA, and the same rail energizes the brake release circuit. Two analog outputs cover ±10 V and support loads of 4 mA for speed or torque readback. The ready relay handles 24 V DC at 1 A, and motion is enabled after a 100 ms ON pulse. These electrical limits help determine appropriate fuse sizes and cabinet wiring for machine installations.

Axis supervision and communication are handled through a SERCOS interface command module that exchanges cyclic data over fiber-optic rings. The drive processes digital servo feedback transmitted over cables up to 75 m long and uses a high-resolution sine position interface for fine interpolation. Its enclosure has an IP65 rating and relies on natural air convection to remove heat while keeping the electronics sealed against dust and spray. The enclosure prevents dust ingress and withstands low-pressure water jets, allowing the drive to be mounted directly on moving axes without an extra enclosure. Noise emissions are reduced during rated motor operation, improving acoustic conditions on the factory floor. Within the Digital Intelligent Servo Drive product group, the unit is Series 1 and Version 1.
