DDS02.1-W100-DA-01-FW by Bosch Rexroth Indramat

The DDS02.1-W100-DA-01-FW is a drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It functions as the electrical interface between a motion-control processor and the motor, converting reference commands into regulated three-phase power so automated equipment can follow programmed speed and position trajectories. By handling the amplification and modulation of control signals, the unit allows machine builders to coordinate multiple axes without embedding power electronics at each motor location. This arrangement keeps the high-power switching stage in the cabinet while the motor remains a simpler electromechanical load at the machine axis.

The controller exchanges setpoint data over an analog interface, so velocity or torque references arrive as ±10 V signals that are translated directly into pulse-width modulation inside the drive. Motor position is returned through digital servo feedback, ensuring high-resolution commutation without manual calibration. Thermal energy is removed by internal air cooling, so cabinet airflow must be maintained even though no external fan module is required. The unit is a digital AC servo drive controller with integrated firing logic and power semiconductors, which reduces wiring to the motor. Its power section is rated for a continuous output of 100 A, allowing it to energize medium-frame servomotors during dynamic machine cycles.

Within the DDS Drive Controllers series, this unit is part of Line 02, so it matches the second-generation layout used in this platform. The drive is Version 1, which corresponds to the connector and control arrangement used on this release. Its modular format supports installation with compatible supply sections and adjacent axes in a shared drive assembly. This arrangement suits multi-axis cabinets where several controllers operate from the same power structure.
