Product Description:

The DDC01.1-K100A-DS47-00-FW is a digital intelligent servo drive manufactured by Bosch Rexroth Indramat for the DDC Digital Intelligent Servo Drives series. As a closed-loop amplifier, it supplies regulated three-phase power to an attached AC servo motor and exchanges command data with higher-level motion controllers. Natural convection removes heat from the housing, allowing the unit to mount inside control cabinets without forced airflow aids. Within automated assembly lines or handling systems, the drive converts low-level position or velocity setpoints into precisely timed current patterns that keep the motor synchronized with the programmed motion profile.

The power section is designed for a continuous output of 100 A while accepting mains at 3 x AC 220/230 V and grid frequencies of 50/60 Hz. Protection routines disengage the inverter when the DC bus rises above 475 VDC or when the phase current reaches 1.5 x rated current, limiting component stress during line surges or stall events. Noise emission is classified as standard for the 100 A to 200 A range, indicating compliance with typical plant acoustic requirements for drives in this current class. A minimum 100 ms power-on pulse must be present so the logic supply can initialize before drive enable. Heat generated at this rating is dissipated by air flowing naturally over the finned enclosure, and the overvoltage threshold coordinates with the rectifier to help avoid capacitor damage.

Motion and diagnostic data travel through the integrated SERCOS Interface, while service tasks such as parameter backup can be performed over the RS-232 port. The analog monitor channel sources up to 4 mA across a span of ±10 V, giving controllers a real-time representation of speed, torque, or other internal variables. Digital servo feedback from the motor encoder closes the loop for position accuracy. The drive is version 1.
