Product Description:
Bosch Rexroth Indramat manufactures the DDC01.2-N050C-R as part of its DDC Digital Intelligent Servo Drives series. Classified as a Digital Intelligent Servo Drive, the unit transforms fixed-frequency mains power into a controlled three-phase output for resolver-equipped motors. This controlled output provides closed-loop torque, speed, and position regulation for automated assembly cells, packaging stations, and machining centers. The drive coordinates motor current with feedback signals to maintain accurate motion as operating loads and commanded speeds change.
The power section supplies up to 50 A of continuous output current while drawing a nominal 6 kVA from the plant supply. Its IGBT bridge uses pulse-width modulation at 8 kHz, a switching frequency that reduces motor acoustic noise and smooths current ripple. Steady internal power dissipation is limited to 500 W, helping control heat accumulation during continuous operation. An integrated bleeder resistor absorbs braking energy with a short-term rating of 10 kW, allowing up to 5 kWs of surplus kinetic energy to be released without an external resistor bank. Resolver feedback is processed by the controller for precise vector regulation of the connected motor. Cabinet airflow must remain unobstructed to maintain semiconductor temperatures within acceptable limits during operation.
The housing stands 635 mm high and has a footprint of 220 × 298 mm, while the complete assembly weighs 21 kg. The IP65 enclosure protects internal components against dust and low-pressure water jets, permitting installation outside filtered cabinets when suitable cable connections are used. Reliable operation is supported at ambient temperatures up to 55 °C, with absolute humidity up to 25 g/m³ and noncondensing relative humidity up to 95%. The drive can be mounted at elevations up to 1,000 m without derating, allowing full output under standard altitude conditions. Noise emission is rated as standard and remains within normal workshop limits. The drive is Series 1 and Version 2, identifying its product generation and design revision.
