Product Description:

The DDC01.2-N050C-DS46-00-FW servo drive is produced by Bosch Rexroth Indramat and belongs to the DDC Digital Intelligent Servo Drives series. It integrates a SERCOS command module with digital servo feedback so that motion tasks can be synchronized over a fiber-optic network while the drive supplies regulated three-phase power to the attached motor. In automated assembly lines, pick-and-place stations, and material-handling axes, it closes the velocity and torque loops locally, reducing PLC load and supporting repeatable positioning. Because the feedback processing is handled inside the drive, setpoint updates and motor response remain closely coordinated during dynamic moves.

This model delivers a continuous motor current of 25 A and can supply a momentary surge up to 50 A to accelerate inertial loads. A mains demand of 6 kVA indicates the required cabinet supply rating, while a continuous bleeder capacity of 0.25 kW dissipates regenerated energy during routine deceleration. The drive has an IP65 enclosure, allowing installation outside a sealed cabinet when the mating connections are protected correctly. Standard cooling draws ambient air across internal heat sinks, and with that airflow the unit supports a sustained mechanical output of 4 kW without derating. Ambient airflow removes heat directly from the power section so the housing can maintain stable operating temperature during continuous duty. SERCOS telegrams carry motion setpoints, while the internal controller supervises thermal behavior during extended operation.

For rapid stops or heavy braking events, the peak bleeder channel absorbs up to 10 kW, and the power section can deliver a peak mechanical load of 8.5 kW for brief production surges. Up to 5 kWs of regenerative energy can return to the DC bus before the bleeder engages, which helps in cyclic applications with frequent deceleration. This arrangement allows returned energy to be managed internally during short braking intervals instead of being released immediately as heat. Operation is permitted up to 1000 m above sea level, and the 21 kg chassis provides a stable mounting base for industrial installations. Noise emission is reduced at the 50 A rating, and the drive is suited to applications that alternate between acceleration, steady running, and controlled braking throughout the duty cycle.
