Product Description:

The DDS02.1-A100-DS23-03 is a drive controller manufactured by Bosch Rexroth Indramat and supplied within the DDS Drive Controllers series. Installed in multi-axis machinery, the unit regulates torque, speed, and position of compatible AC servomotors through closed-loop communication with a supervisory PLC. It converts control commands into regulated motor current for coordinated axis movement in industrial automation. This makes it a central motion component in systems that require synchronized servo operation across several machine functions. The controller is intended for applications that need precise response to changing load and motion commands.

Its communication link is the SERCOS interface, a fiber-optic real-time bus that transmits setpoints and diagnostic data between the drive and master in 2 ms cycles. The controller delivers a continuous output of 100 A, which is the maximum phase current it can supply to the motor windings without derating. Heat is removed by external air cooling, so the installation must provide a duct that channels ambient airflow directly through the heat sink fins. For position verification, the unit reads digital servo feedback, so encoder information is processed directly and faults can be detected quickly. The drive belongs to Line 02 in the product range.

As a Digital AC Servo Drive Controller, the device executes current, velocity, and position loops within microseconds, allowing multiple axes to synchronize over a single optical ring. Because the control loops run inside the unit, command updates can be applied with very little delay at the motor. The unit mounts on a common cold plate and uses shared DC bus links with compatible power supply and network modules. This arrangement keeps the electrical interface compact and supports coordinated operation with other drive components in the same system. Hardware Version 1 identifies the initial release of this model.
