Product Description:
The DDC01.2-K050A-D is a digital intelligent servo drive produced by Bosch Rexroth Indramat within the DDC Digital Intelligent Servo Drives series. As a closed-loop controller, it converts line power into regulated three-phase output and interprets motor feedback, allowing synchronous and induction motors to maintain commanded torque and speed profiles in automated machinery. This arrangement lets the unit correct for load changes quickly, which helps the motor hold the requested motion profile during acceleration and steady running. Digital servo feedback from the connected motor is processed in the internal control card, enabling precise position loops during operation.
This drive draws a three-phase supply of 3x220 V (+15%/-10%) or 3x230 V (+10%/-15%) at an input frequency of 50 to 60 Hz. Its power section is rated for a continuous output of 50 A, giving headroom for rapid accelerations without current foldback. Operation is intended in ambient temperatures from +5 to +45 °C, and within that band the unit cools through natural convection, so no forced-air fan is required. The drive has an enclosure rating of IP65, which prevents dust ingress and resists high-pressure water jets from reaching live circuitry. Absolute humidity should not exceed 25 g/m³ to help prevent condensation on the laminated bus bars and gate drivers.
The housing tolerates peak ambient exposure up to +55 °C for short durations and can be installed at elevations up to 1000 m without derating. For service access, a minimum air-outlet clearance of 300 mm above the heat sink fins is required so convective airflow is not obstructed. The required clearance above the cooling surfaces helps preserve the natural airflow path through the enclosure. Long-term storage is permitted from -30 to +85 °C, allowing the unit to be kept in unconditioned warehouses. The drive is a digital intelligent servo drive in Series 1 and Version 2.
