Product Description:

The DDS02.1-W100-DA14-00 is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. Installed in multi-axis automation racks, it receives speed and torque commands from higher-level motion processors and modulates three-phase power to a connected servo motor. It acts as the electrical link between the control section and the motor, converting low-level command signals into regulated armature current. By closing the drive loop inside the cabinet, it helps mechanical axes follow programmed motion profiles with repeatable accuracy during positioning and speed-controlled operation. It can be used wherever a centralized rack controls several axes that must accelerate, decelerate, and hold position under varying process loads.

The unit exchanges setpoint and status data through an analog interface, so command values are transmitted as voltage or current levels instead of a digital network link. A continuous output capacity of 100 A allows the drive to supply medium-frame servo motors that need substantial torque during acceleration and load changes. Thermal energy is dissipated by internal air cooling, which draws cabinet air across the heat sink, so the enclosure must provide a clear airflow path. Position information is processed through digital servo feedback, allowing high-resolution velocity and position control without an additional encoder converter. Because the reference path is analog, the drive can work with controllers that provide conventional speed or torque signals through standard electrical interfaces.

The housing is identified as Line 02, indicating the second design line used for this DDS platform. This unit uses the DA14 configuration and is listed as Version 1. It is intended for use with compatible servo motors that employ digital feedback devices, including absolute or incremental transducers. During operation, the controller synchronizes output current with rotor position so low-speed motion remains smooth and responsive. In cabinet-mounted systems, this arrangement supports coordinated axis control where stable current regulation and closed-loop feedback are required. It also supports applications that require precise response to small speed corrections during continuous motion.
