Product Description:

The DDC01.1-K100A-DA01-00 is a digital intelligent servo drive produced by Bosch Rexroth Indramat within the DDC Digital Intelligent Servo Drives series. Designed as the power and control node between a PLC and an Indramat servomotor, the unit converts incoming line power into controlled three-phase pulses for position, velocity, and torque regulation in automated assembly lines, packaging equipment, and material-handling axes. It integrates power electronics, control functions, and regenerative braking in a sealed enclosure, which keeps the overall drive package compact and suitable for direct machine mounting.

It supplies a continuous output power of 12 kW and can reach 17 kW during short acceleration bursts. The power bridge is rated for 100 A, and upstream protection must accommodate a maximum input demand of 18 kVA. Pulse-width modulation is performed at 4 kHz, a switching speed selected to reduce audible noise and smooth motor current. An analog interface command module transfers setpoints and status signals to higher-level controls, while digital servo feedback from the motor keeps the velocity loop closed during changing load conditions. Under nominal load, the drive dissipates 420 W of heat, which is removed by natural convection through the finned housing.

Regeneration is handled by an internal bleeder that can absorb 0.5 kW continuously and up to 20 kW in short peaks, and the associated energy limit is 7 kWs. The enclosure has an IP65 rating and uses air cooling, so the drive does not require a separate cooling fan. Safe operation is permitted up to 55 °C ambient with output derating, and relative humidity can reach 95% without condensation. The unit has a mass of 22 kg and is Function Code 01, Series 1, and Version 1. Noise emission remains within the standard range for 100 A drives.
