Product Description:

The DDS02.1-W015-DS01-02-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. It functions as the central power stage between a motion controller and an AC servo motor, regulating phase voltage and current so machines can perform indexed positioning and coordinated multi-axis moves in industrial automation lines. Its modular card format allows the unit to slide into a multi-axis rack beside other DDS modules. In rack-based systems, that layout keeps several axes grouped in one enclosure and supports compact drive cabinet arrangements.

The controller exchanges cyclic position, velocity, and diagnostic data through a SERCOS interface, allowing fiber-optic networking with compatible drives and CNC motion cards. During operation, it supplies a continuous phase output of 15 A, which indicates the motor current the unit can provide during steady operation without thermal overload. Heat generated by the power electronics is removed by internal air cooling, so the enclosure must provide airflow across the heat sink. Rotor position is returned through digital servo feedback, enabling closed-loop regulation without analog tachometers. Because feedback is processed inside the controller, the drive can correct speed and position deviations directly at the power stage during changing load conditions. The unit is a Digital AC Servo Drive Controller that produces pulse-width-modulated output for synchronous and induction motors while monitoring faults in real time.

The controller is assigned Function ID 01. It belongs to Line 02 in the series, which indicates the module group used for this rack platform and keeps its mechanical form and bus connection layout aligned with related units. The hardware release is Version 1. These identifiers distinguish this controller from other DDS variants and keep the product description clear when matching it with compatible system components. They are also useful when verifying module compatibility within multi-axis installations that use the same DDS backplane and connection arrangement.
