Product Description:

The DDC01.2-N050C-DL01-01-FW is a digital intelligent servo drive manufactured by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. An integrated single-axis positioning command module processes motion profiles and works with the drive's digital servo feedback channel to close the control loop on a connected motor. In automated cells, the unit translates controller instructions into regulated pulse-width modulation so that actuators reach target positions at the required speed and repeatability. Because the positioning function is built into the drive, command handling and feedback evaluation occur in one housing. This supports consistent axis response during indexing, start-stop movement, and other repetitive motion tasks.

The power stage delivers a continuous output of 50 A and modulates that current at a carrier frequency of 8 kHz, allowing fine torque resolution while limiting audible switching noise. Line supply demand is 6 kVA, and excess kinetic energy is sent to an internal bleeder circuit rated for 10 kW peak and 0.25 kW continuous dissipation, which protects the DC bus during deceleration. The controller section is energized with 24 V DC at 150 mA, separating logic electronics from main power. Up to 5 kWs of regenerated energy can be absorbed per braking event. Cooling is handled through internal air channels, and Function code 01 with Version 01 marks the installed control feature set.

Total heat rejected during steady operation is 500 W, a value used when sizing cabinet airflow. The housing meets IP65, allowing direct machine mounting where dust or low-pressure water jets are present. Reliable service is permitted at ambient temperatures up to 55 °C and elevations up to 1,000 m, provided relative humidity does not exceed 95 percent and absolute humidity stays below 25 g/m³. The drive has a mass of 21 kg. It is built as Series 1, Version 2 hardware, and those operating limits should be observed to avoid overheating or moisture-related issues.
