Product Description:

The DDC01.1-K050A-DG05-00 is a digital intelligent servo drive produced by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. It is designed to control synchronous motors through closed-loop regulation in automated machinery, using integrated signal processing to interpret digital servo feedback from the attached encoder and generate precise phase currents. This allows the drive to support accurate speed control and repeatable axis motion in automated systems. The controller uses encoder information to keep commanded motor position and speed aligned with the required motion profile.

This unit delivers a continuous mechanical output of 8.5 kW while drawing a rated current of 50 A. The power section can accept a maximum connected load of 12.8 kVA, and internal circuitry dissipates brake heat with a bleeder rated at 0.25 kW continuously and capable of 10 kW for short peaks. The bleeder absorbs braking energy inside the drive during deceleration events. Regenerative events are limited to 4 kWs of returned energy before the drive must re-accelerate the motor or use external dumping. Total power loss at full rating is 300 W, so natural convection is sufficient for cooling. A PWM carrier fixed at 4 kHz shapes the output waveform, and the noise emission category is Standard (100 A to 200 A) during nominal operation. Function code 05 is assigned to the application parameter set loaded at the factory, and the product is group Digital Intelligent Servo Drive, series 1, version 1.

The housing carries a maximum ambient operating limit of +55 °C when derating is applied, with reliable performance up to 95% relative humidity. Its IP65 enclosure blocks dust ingress and low-pressure water jets, allowing cabinet-free mounting close to the motor. Cooling relies on air moving over finned surfaces, so no fans or liquid circuits are required. At 21 kg, the enclosure provides substantial thermal mass while remaining practical for machine mounting. A switching frequency of 4 kHz helps minimize current ripple and preserve torque smoothness when the system handles high-inertia loads.
