Product Description:

The DDS02.1-W100-DS56-00-FW is a Digital AC Servo Drive Controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. Designed for closed-loop automation, the unit receives motion commands, modulates inverter output, and protects connected AC servomotors during acceleration, braking, and positioning tasks. In industrial machinery, it translates numerical control instructions into repeatable mechanical movement for synchronized multi-axis systems such as machine tools, printing stations, and assembly equipment. Because it serves as the interface between the control system and the motor, it supports accurate torque, speed, and position response during changing machine cycles. Centralized installation in a controller rack also keeps the drive layout compact and organized.

The drive exchanges real-time process data over the SERCOS interface, a fiber-optic ring used for low-latency communication between the drive, the machine PLC, and neighboring axes. A continuous output capability of 100 A allows the module to power medium- to large-frame Indramat servomotors without external current boosters. Heat is removed by internal air cooling, so the unit relies on airflow from inside the control cabinet rather than an attached fan or heat sink plate. This cooling method makes cabinet airflow important for stable thermal performance during sustained load. The electronics and power sections are part of line 02, which indicates compatibility with other second-generation components that use the same mounting rails and DC bus arrangement.

Motor encoder signals return through digital servo feedback, allowing the controller to regulate current and speed loops without a separate resolver card. This feedback method supports accurate response when axis load or commanded speed changes during operation. The unit is Version 1, identifying this product revision. Its layout suits multi-axis cabinets where several drive modules are mounted side by side and connected through a common control structure. The controller is intended for installations that require repeatable motion behavior across coordinated axes and centralized drive placement inside the enclosure.
