Product Description:

The DDC01.1-K050A-DA02-00 is a servo drive manufactured by Bosch Rexroth Indramat and part of the DDC Digital Intelligent Servo Drives series. It converts command values from higher-level controllers into regulated three-phase power for synchronous motors while reading incremental position data to keep the motor at the commanded set point. By combining control logic, the power stage, and diagnostics in one sealed assembly, the unit can be mounted close to the working axis and simplify cabinet design in automated production lines.

At the electrical interface, the drive delivers a rated current of 50 A and draws as much as 12.8 kVA when the axis reaches maximum load. Its inverter can sustain a continuous mechanical output of 8.5 kW and switches the IGBTs at a carrier frequency of 4 kHz to minimize torque ripple. Normal operation dissipates only 300 W, and that heat is removed by natural convection across the fins, eliminating the need for forced cooling. An analog interface command module receives velocity or torque references, while digital servo feedback maintains closed-loop precision. Installation is permissible up to 1000 m altitude without derating, and the unit has standard acoustic emission for the 100 A to 200 A class with a mass of 21 kg.

During regenerative braking, the internal bleeder handles peaks of 10 kW and can dissipate 0.25 kW continuously, with an energy buffer of 4 kWs for single deceleration events. The housing meets IP65, enabling direct machine mounting in dusty or damp zones. Ambient limits allow operation up to 55 °C with reduced output and up to 95% relative humidity if condensation is avoided. Function code 02 identifies the installed feature set, and the product is a Digital Intelligent Servo Drive in Series 1 and Version 1.
