Product Description:

The DDC01.1-K050A-DL43-01-FW is a servo drive from the DDC Digital Intelligent Servo Drives series manufactured by Bosch Rexroth Indramat. Designed for closed-loop motion tasks, the unit forms the power and control interface between the AC line supply and a servo motor. It decodes digital servo feedback and runs the built-in single-axis positioning command module to move actuators with the speed and positional accuracy demanded in automated assembly lines and machine tools. This arrangement supports precise speed regulation and repeatable positioning in single-axis motion applications.

The drive is rated for a motor current of 50 A, and its input section requires 6 kVA of apparent power during continuous operation. The power inlet accepts a three-phase supply of 3 x AC 230 V at 50 to 60 Hz, allowing connection to standard industrial distribution panels. A continuous mechanical output of 4 kW matches medium-frame Indramat motors, and short-term demands up to 8 kW are supported without derating. Internally, natural convection air cooling removes the 500 W of power loss generated by the power semiconductors and control electronics. Motion is monitored through digital servo feedback, while +/-10 V diagnostic outputs provide real-time analog status signals for external monitoring. The command module uses function code version 01, and the noise emission is standard for the 100 A to 200 A range.

For electrical protection, the power section trips above 475 V DC link voltage and disconnects below 200 V to guard against line-supply anomalies. Excess kinetic energy returned during braking is routed to an internal bleeder resistor rated for 0.25 kW continuous dissipation and up to 10 kW in short peaks, while the energy store is capped at 5 kWs to protect internal components. During rapid acceleration, the power stage can deliver 8.5 kW of peak mechanical output without exceeding its thermal limits. A dedicated brake control output supplies the motor's holding brake with 24 V DC so vertical axes can remain secure when system power is removed.
