Product Description:

The DDC01.1-K150A-DL02-00 is a digital intelligent servo drive manufactured by Bosch Rexroth Indramat as part of the DDC Digital Intelligent Servo Drives series. It integrates power conversion, regenerative handling, and a single-axis positioning command module to control brushless servo motors in synchronized production lines, packaging equipment, and material-handling cells. By combining these functions in one sealed housing, the drive simplifies cabinet wiring and maintains consistent motion profiles.

During normal duty, the drive delivers a continuous output current of 90 A, allowing it to sustain the motor’s rated torque without overheating. For rapid acceleration or impact loads, it can momentarily supply a peak of 150 A, supported by its power section and thermal design. To feed this output stage, the mains must provide up to 22.5 kVA at maximum load, while internal losses stay at 540 W to help maintain overall efficiency. Mechanical shaft power available to the axis reaches 15 kW, coordinated by the internal Single Axis Positioning module that executes Function Code 02 sequences. A carrier frequency of 4 kHz modulates the PWM bridge, which improves current ripple and reduces audible noise in the standard 100 A to 200 A range. Digital servo feedback closes the velocity loop for sub-millisecond corrections.

Heat is removed by natural convection air cooling, so no external fans are required and the drive retains its sealed IP65 enclosure rating against dust and water jets. The integral bleeder resistor absorbs up to 40 kW of instantaneous regenerative power, storing 10 kWs between cycles while averaging 1.0 kW continuously. Operation is permitted up to 1000 m altitude and a maximum ambient temperature of +55 °C without derating. The housing weighs 22 kg, providing sufficient mass for passive cooling while still allowing installation in compact machines.
