Product Description:

The DDS02.1-A150-DS54-00-FW is a drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It is used in multi-axis automation to modulate three-phase servo power modules and coordinate motion commands from higher-level control systems. Within a cabinet, the unit links the power stage, the communication network, and the connected servo motor, converting command data into regulated phase currents for position and speed control. By regulating motor current instead of switching line power directly to the motor, the controller supports accurate servo motion in automated production equipment.

The controller communicates through a SERCOS interface, allowing deterministic fiber-optic data exchange with CNC or PLC masters. A continuous output capacity of 150 A permits it to drive high-torque servo motors without an external booster stage. Thermal management relies on external air from outside the control cabinet, which carries heat away from the heat sink without adding that thermal load to the enclosure interior. Position information from the motor is returned through digital servo feedback, providing the electronic data needed to close the velocity and position loops inside the drive. The fiber-optic link also supports cyclic command updates and status reporting in electrically noisy cabinet environments.

The unit is Version 1 and belongs to Line 02. It is classified as a Digital AC Servo Drive Controller, so current regulation and motion-related signal processing are handled numerically inside the unit rather than by direct line switching. This approach supports smooth current synthesis during acceleration, deceleration, and steady-speed operation. The controller uses the standard slide-in DDS form factor and front connections for cabinet installation beside compatible system modules.
