Product Description:

The DDC01.1-K100A-DL30-01-FW is a drive unit from the DDC Digital Intelligent Servo Drives series manufactured by Bosch Rexroth Indramat. This servo drive regulates torque, speed, and position of synchronous motors in automated machinery. It incorporates the Single Axis Positioning command module, allowing stand-alone axis control and program execution directly in the drive. Because the positioning module is integrated, basic motion routines can be executed inside the drive rather than in a separate external control stage. This makes the unit suitable for applications that need local axis management together with standard servo regulation.

Electrically, the drive delivers a continuous output of 100 A, and its protection circuit trips at 1.5 × rated current to prevent thermal overload. The DC link overvoltage limit is 475 V, and the controller begins status signaling once the intermediate circuit reaches 200 V. Motor position is processed through digital servo feedback with a resolution of 2,097,152 incr/rev and an accuracy of ±0.5 angular minutes, supporting precise contouring and stable position control. This feedback arrangement gives the drive fine rotor-angle data during speed changes and accurately controlled moves. Natural convection cooling removes heat without auxiliary fans, the noise emission is standard, and the drive is a series 1 unit with function code version 01 and hardware version 1.

Control electronics are energized by a 24 V DC supply, and the enable circuit draws only 150 mA, simplifying low-power supervisory wiring. That supply rail is also routed to the motor brake relay, so no separate low-voltage source is needed for brake release, and the brake has a wear limit of 20,000 revolutions. Overvoltage events up to 745 V are tolerated momentarily, after which the overvoltage trip disconnects the unit. The stored DC bus energy then supports an orderly shutdown sequence instead of an abrupt loss of control.
