Product Description:

The DDC01.2-N050C-DA01-01-FW is a drive unit from the DDC Digital Intelligent Servo Drives series produced by Bosch Rexroth Indramat. It combines a digital servo feedback loop with an analog interface command module, allowing precise control of motor speed and position in handling and packaging equipment. This arrangement lets the drive respond to changing load conditions while following reference values from an external controller. It is intended for servo applications that require stable closed-loop motion with an analog command structure. The unit is series 1, function code 01, and version 2. Noise emission is reduced at the standard operating point.

Its power channel is rated for 50 A of continuous output current, delivered through a pulse-width-modulated bridge that switches at 8 kHz. This switching method produces controlled motor current with fast response during acceleration and deceleration. The converter draws 6 kVA from the line supply and has 500 W of internal power loss that is removed by built-in cooling fans. For motor output, the drive supports a continuous load of 4 kW, while the bleeder circuit dissipates 0.25 kW during steady regeneration and can absorb up to 5 kWs of energy during transient events. Regenerated energy above that level is directed to a braking resistor so the DC link voltage remains within a safe range.

The overvoltage protection stage can momentarily absorb 10 kW of braking power, giving the axis time to coast to a controlled stop during rapid deceleration. Operation is permitted in ambient temperatures up to 55 °C, at installation heights up to 1000 m, and in relative humidity up to 95% without condensation. An IP65 ingress rating allows the housing to resist dust and water jets, which supports use in exposed machine areas. The enclosure weighs 21 kg, which helps keep the unit more compact than larger drives of similar capacity and limits added load on the mounting surface.
