Product Description:

The DDC01.1-K050A-DL26-00 is a digital intelligent servo drive built by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. It incorporates a command module for single-axis positioning, allowing the unit to execute motion profiles without an external motion card. In automated assembly stations, the drive converts three-phase mains power into controlled armature current and processes digital servo feedback from the motor to maintain accurate velocity and position during repeated moves. This arrangement suits indexing tables, transfer axes, and other point-to-point applications that benefit from onboard control.

Inside its IP65 enclosure, the drive connects to a three-phase supply with a connected load of 12.8 kVA. The rated output current is 50 A, which is the continuous line current the internal IGBT stage can supply while natural convection cooling keeps semiconductor junctions within limits. A mechanical continuous power rating of 8.5 kW matches the needs of medium-inertia axes used on tooling or packaging machines. Up to 3000 blocks of program memory allow the resident controller to store positioning sequences locally, which reduces dependence on external control for repeated tasks. Pulse-width modulation at 4 kHz lowers motor torque ripple, although it also contributes to 300 W of power loss that must be removed by airflow. Additional energy handling is provided by a continuous bleeder resistor rated at 0.25 kW.

During aggressive deceleration, the internal shunt can absorb a peak of 10 kW and capture regenerated energy up to 4 kWs before it is dissipated. The module is series 1 and version 1, uses standard noise emission in the 100–200 A class, and weighs 21 kg for cabinet mounting. Its sealed enclosure allows the drive to be placed closer to the machine than open-frame units, while the integrated control and braking functions keep the overall installation compact. This layout also helps keep wiring runs short in machine-mounted installations.
