Product Description:

The DDC01.1-K100A-DG09-00 is a digital intelligent servo drive produced by Bosch Rexroth Indramat in the DDC Digital Intelligent Servo Drives series. Intended for industrial automation, the unit combines high-current power electronics with closed-loop motion control so it can operate brushless actuators from a single compact module. By processing motor-mounted encoders through its digital servo feedback channel, the drive controls position, velocity, and torque with the consistency required for packaging lines, transfer systems, and CNC auxiliary axes. This arrangement lets the controller respond quickly to changing loads while maintaining stable axis behavior during repeated motion cycles.

During continuous duty, the drive delivers 35 A of output current, which corresponds to a thermal load of 6 kW at the DC bus. For intermittent overloads, it permits 70 A for short intervals and supports a mechanical demand of 12 kW. The power stage tolerates higher surges up to 100 A and 17 kW at peak, and the rated current matches this value. A bleeder circuit dissipates 0.25 kW continuously or 20 kW in short bursts, while the DC link can absorb 10 kWs of regenerated energy. Switching is executed at a pulse-width modulation frequency of 4 kHz to help keep motor ripple currents low. Cooling relies on natural air convection, and acoustic output remains within the standard range for this rating class.

The installation must provide 18 kVA of input power, and the internal electronics release only 500 W as heat, which supports passive dissipation through the sealed housing. The enclosure achieves IP65 protection, allowing cabinet-free mounting on machinery frames, and the total mass is 22 kg. The drive is Version 1 and Series 1. Its sealed format also suits machine-mounted layouts that place the unit close to the driven axis.
