Product Description:

The DDC01.1-K050A-DG01-00 is a servo drive manufactured by Bosch Rexroth Indramat for closed-loop motion control within the DDC Digital Intelligent Servo Drives series. It regulates torque, speed, and position of AC servo motors in automated machinery. The unit acts as the link between the supply network and the motor phases while handling feedback and protective logic. This arrangement lets the drive respond to command changes while maintaining controlled motor operation during acceleration, steady running, and changing load conditions.

This drive draws power from a three-phase mains of 3 × 230 VAC (+10 %/-15 %) at a line frequency of 50–60 Hz. Under continuous operation, it supplies a rated output current of 50 A, and short-term surges are limited by an overcurrent threshold of 1.5 × rated current. Startup circuits require a minimum power-on pulse of 100 ms to recognize a run command, and thermal monitoring issues an over-temperature warning after a 30 s delay to allow a controlled shutdown before damage occurs. It relies on digital servo feedback from the connected motor to close the velocity and position loops while keeping noise emission within the standard 100 A to 200 A acoustic class.

Control electronics are supplied with a separate 24 VDC so that logic remains active during mains interruptions. Because the logic supply stays available, the drive can retain control functions long enough to process status conditions and react in an orderly way during a supply dip. DC link protection trips at 475 V to safeguard the bus capacitors. The enclosure is rated IP65, and heat is removed by natural convection air cooling. Installation requires an air outlet clearance of 300 mm above the heatsink and 65 mm of side clearance for lateral airflow. Adequate clearance around the housing helps air move freely across the heatsink and along the sides of the unit.
