Product Description:

The DDC01.1-K050B-DL29-01-FW is a digital intelligent servo drive produced by Bosch Rexroth Indramat within the DDC Digital Intelligent Servo Drives series. As a closed-loop power stage, it translates motion commands from higher-level controls into regulated current and voltage for servo motors in automated machinery. By monitoring motor feedback, the drive supports precise position and velocity control during synchronized industrial motion. This layout makes it suitable for single-axis motion tasks where stable response and accurate tracking are required. It can be used in packaging, handling, and other machines that require repeatable servo regulation under changing load conditions.

At the heart of this model is a bleeder circuit that can dissipate 0.25 kW continuously and reach 10 kW in short bursts, so kinetic energy returned during deceleration is converted to heat. The continuous output current is 25 A, which is the long-term load the power electronics can sustain without overheating. For transient operation, the PWM stage switches at 16 kHz, a carrier frequency that helps reduce motor acoustic noise and ripple. Even with this switching rate, overall controller power loss is limited to 300 W, which helps simplify cabinet thermal design. The single-axis positioning command module works with digital servo feedback to maintain closed-loop control during motion.

For installation, the housing carries an IP65 protection rating, allowing direct mounting on machinery where dust and water spray are present. Natural convection air cooling removes internal heat, and the unit can operate in ambient temperatures up to 55 °C at altitudes not exceeding 1000 m. When rapid motion cycles occur, the intermediate circuit can store as much as 4 kWs of regenerated energy before it is routed to the bleeder. The peak output current reaches 50 A, and noise emission is classified as reduced at that load. The unit weighs 21 kg. The product is function code 01, series 1, and version 1.
