Product Description:
The DDS02.1-W015-DS51-01-FW is manufactured by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. Designed for cabinet installation, the device forms the interface between a higher-level CNC or PLC and a synchronous or induction servo motor. By modulating drive current in real time, it maintains commanded velocity and position in automated machining centers, packaging lines, and material-handling stations where deterministic digital communication and feedback are required. It supports AC servo motors that rely on high-resolution position loops, making it suitable for multiaxis gantries and robotic cells. This arrangement lets the drive handle the motion loop directly while the machine control sends the required speed or position commands. The unit is intended for multiaxis systems where coordinated response between the controller, motor, and feedback device is important.
The controller exchanges motion data over the SERCOS interface, allowing cyclic setpoint and diagnostic traffic to pass on a fiber-optic ring with microsecond timing. Internally, it is rated to supply 15 A of continuous output current, a level that matches medium-frame motors used for feed or spindle functions. Heat generated by the power stage is removed by air from inside the control cabinet, so no external blower or liquid circuit is required, but cabinet airflow must be maintained. Protection against accidental contact is provided by the IP20 housing classification, which still requires mounting behind a door. For rotor position and speed information, the unit relies on digital servo feedback, enabling fine interpolation of incremental counts and automatic parameter identification during startup.
Reliable operation is permitted at ambient temperatures between 0 to 45 °C, so the controller can run in standard enclosed electrical cabinets without thermal derating. The electronics can be stored or shipped between -30 and 85 °C without damage when the unit is not powered. Installation heights may reach 1000 m above sea level before convection cooling or voltage correction becomes necessary. The controller is part of Line 02 and carries Function ID version 01.
