Product Description:
The DDC01.1-K100A-DS50-01 is a servo drive produced by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. It forms the interface between a plant controller and a compatible synchronous or induction motor, modulating three-phase power so automated machinery can follow commanded motion profiles accurately. The unit performs drive control functions locally, which reduces the processing load on the PLC and supports decentralized motion axes on the factory floor. Digital servo feedback closes the position loop, while the SERCOS command module provides deterministic communication with the higher-level controller.
The drive has an apparent power demand of 18 kVA and produces 500 W of power loss during operation. Heat is removed through natural convection air cooling, so the installation must provide adequate clearance around the housing for unrestricted airflow. The rated and peak current are both 100 A, while the continuous current capability of 35 A supports sustained motor operation without thermal overload. For intermittent duty, the S6-100 s current allowance reaches 70 A. Carrier modulation operates at 4 kHz, providing smooth torque regulation while limiting switching losses in the power stage. The IP65 enclosure protects internal components from dust and low-pressure water jets, permitting installation outside a control cabinet when applicable installation requirements are met. The unit has Function ID Version 01 and belongs to Series 1. Its mass is 22 kg, and its acoustic emission category is Standard for drives in the 100 A to 200 A range.
A dedicated brake resistor stage manages regenerative energy returned to the drive when the connected motor decelerates. The resistor can absorb a peak braking load of 20 kW and dissipate 0.25 kW continuously. Energy returned during a stopping event must remain below 10 kWs, and the DC-link warning threshold is set at 75 percent. Rated operation is maintained at ambient temperatures up to 55 °C, provided that cooling airflow remains unobstructed. The permissible installation altitude extends to 1,000 m above sea level without requiring derating. Motor power and feedback cables can have a maximum length of 75 m without exceeding applicable voltage-drop or signal-timing limits. These cable limits allow the drive to be positioned away from the motor while maintaining stable power delivery and reliable feedback communication.
