Product Description:

The DDC01.2-N050C-DL30-01-FW is a drive controller manufactured by Bosch Rexroth Indramat within the DDC Digital Intelligent Servo Drives series. The unit combines power electronics, closed-loop regulation, and a single-axis positioning command module to run an AC servo motor in automated machinery. Acting as the interface between higher-level control and the motor, it supplies regulated three-phase output, interprets digital servo feedback, and executes stored motion blocks for precise positioning tasks. This arrangement allows the controller to manage axis movement directly while maintaining accurate speed and position control during automatic operation.

Its continuous output capability reaches 25 A, so the drive can deliver steady torque without thermal derating, while short-term demand is handled by a peak current limit of 50 A. Mains supply sizing must accommodate a power requirement of 6 kVA under full load, and the output stage uses a pulse-width-modulation frequency of 8 kHz to reduce current ripple. The enclosure carries an IP65 rating, which allows mounting directly on the machine in locations where dust and low-pressure water exposure are present. Standard cooling removes heat through integrated fins, and the digital servo feedback interface works with the motor encoder for closed-loop control. The single-axis module can also store up to 3000 program blocks for stand-alone trajectory execution.

Energy returned by decelerating loads is absorbed by an internal bleeder that dissipates 0.25 kW continuously and up to 10 kW in short bursts. If regenerated energy rises beyond that continuous level, the shunt circuit stabilizes the DC bus during braking events. Mechanical output can reach 4 kW, and steady operation produces about 500 W of power loss that must be removed by the standard cooling path. Operation is permitted up to 1000 m above sea level without derating, and PWM noise shaping helps reduce audible switching noise during use. The drive is Function Code Version 01, Series 1, and Version 2.
