Product Description:

The DDC01.2-N050C-DL02-01-FW is a closed-loop drive unit produced by Bosch Rexroth Indramat in the DDC Digital Intelligent Servo Drives series. As a digital intelligent servo drive, it combines power conversion, motion control, and feedback processing to run brushless servo motors in automated machinery. The unit interprets positioning commands, modulates current to the stator, and returns precise position data to the master controller, making it suitable for pick-and-place gantries, packaging stations, and similar single-axis tasks. This arrangement supports accurate starts, stops, and speed changes during repetitive machine cycles.

With a rated output current of 50 A, the drive can energize medium-frame servo motors while operating within the standard reduced-noise class. The analog interface offers a span of ±10 V, and this signal can be routed to external recorders or drives when the load remains at 4 mA. Internally, current and velocity loops switch at 8 kHz, so torque commands reach the motor quickly. The mains supply must deliver 6 kVA, and normal conversion losses of 500 W are removed by the standard cooling arrangement. The cast housing carries an IP 65 rating that protects the electronics from dust and water jets during floor-level installation.

During deceleration, the bleeder circuit absorbs returning energy from the motor. It can handle 10 kW in short bursts and dissipate 0.25 kW continuously, so braking energy remains within the unit's thermal capacity. If a stop generates more than 5 kWs, an external resistor is required. The single-axis positioning module can store up to 3000 program blocks, and digital servo feedback can be cabled as far as 75 m from the motor, which allows flexible placement within larger machines. Continuous mechanical shaft power reaches 4 kW, and the 21 kg enclosure is built as Series 1, Version 2 with function code 02-01.
