Product Description:

The DDC01.1-K100A-DS04-01 is a servo drive unit built by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. In an automation cell, the drive converts fixed-frequency factory power into controlled motor current and variable-frequency output for synchronous or induction motors, enabling coordinated axis positioning and velocity control on assembly lines and packaging equipment. As a stand-alone drive, it integrates logic, power electronics, and fieldbus communication inside a sealed housing suited for direct machine mounting. This arrangement lets the unit handle drive regulation locally while a higher-level controller sends motion commands over the network.

Electrical performance centers on a three-phase input of 3 x 230 V AC (+10%/-15%) that is rectified and buffered in the DC link. Under nominal conditions, the inverter can supply 100 A of continuous output to the motor. Overload protection trips when phase current rises to 1.5 x rated current, while additional circuitry monitors link voltage; shutdown occurs above 475 V or below 200 V to guard against regeneration surges and brownouts. Function code 04 and version 01 identify the installed control set for this drive. These limits help keep the power section within a stable operating range during acceleration and deceleration. The noise emission is standard for the 100 A to 200 A class, and cooling is done by natural convection so external panel fans are not required.

Application integration is managed through the embedded SERCOS Interface command module, which exchanges real-time setpoints and diagnostics over fiber-optic rings. Rotor position returns via Digital Servo Feedback, enabling rapid current loops without external encoders. The housing carries a protection rating of IP65, allowing direct mounting on moving machine axes where oil spray and dust are present. The sealed enclosure helps protect internal electronics when the drive is mounted close to the process area. With the detachable blower hood installed, the overall height is 775 mm, so the enclosure must allow enough vertical clearance. Reserve connectors accommodate future option cards for I/O expansion without altering the base dimensions.
