Product Description:

The DDC01.2-N050C-DL43-01-FW is a digital intelligent servo drive produced by Bosch Rexroth Indramat within the DDC Digital Intelligent Servo Drives series. It controls a single rotary or linear axis and supplies regulated power to the motor in automated machinery. A built-in single-axis positioning module executes motion profiles locally, and digital servo feedback from the motor lets the drive hold precise position, speed, and torque during high-cycle operation. This arrangement supports coordinated motion in equipment that requires fast response and repeatable axis control.

For continuous duty, the drive supplies 4 kW of mechanical power and uses internal cooling to move heat away from the power stage. Short-term demands reach 8 kW, and peaks climb to 8.5 kW during rapid acceleration. The power devices switch at 8 kHz, and the inverter delivers 50 A while operating in the 50 A reduced-noise class. Surplus DC bus energy is routed to an internal bleeder that dissipates 0.25 kW continuously, while higher pulses are absorbed up to 5 kWs. Normal operation limits heat loss to 500 W, which helps reduce the thermal load inside the enclosure. The unit uses function code 01 and is Series 1, Version 2.

During hard decelerations, the bleeder stage can momentarily accept 10 kW, helping prevent overvoltage when large inertial loads return energy to the drive. The unit draws 6 kVA from the mains at full mechanical demand, and its internal cooling arrangement keeps semiconductor temperatures within acceptable limits without external fans or liquid circuits. An IP65 enclosure protects the electronics against dust ingress and water jets, allowing direct mounting on machinery. The drive weighs 21 kg, which eases handling during installation and helps limit the load placed on the mounting structure. This combination of power handling, energy dissipation, and enclosure protection fits applications such as indexing tables, feeders, and pick-and-place axes with rapid duty cycles.
