Product Description:

The DDS02.1-A100-DS06-02-FW/S002 is a digital AC servo drive controller from Bosch Rexroth Indramat in the DDS Drive Controllers series. It regulates AC servo axes through closed-loop current and velocity control, which helps the motor follow commanded motion with stable response during coordinated machine cycles. The unit is part of Line 02, placing it within an early DDS platform used for modular, cabinet-mounted automation systems. Its layout suits machines where multiple axes must operate from a common control structure while maintaining consistent drive behavior.

The drive exchanges command and feedback data over the SERCOS interface, allowing fiber-optic communication with the system PLC and synchronized data transfer between the controller and the motion network. Cooling is provided by external air from outside the control cabinet, so the installation must supply clean airflow to carry heat away from the power components. The power section can deliver a continuous output of 100 A, which means the supply path and protective devices must be matched to that current level. An enclosure rating of IP20 limits the unit to protected indoor cabinet installation rather than open exposure on the machine. Reliable operation is intended for ambient temperatures from 0 to 45 °C, and operation outside that range requires reduced loading or additional cooling.

The servo loop relies on digital servo feedback from the connected motor, so position and speed information returns directly to the drive for closed-loop regulation. Installation is permitted up to 1000 m above sea level without changing the stated thermal capability. During storage or shipment, the electronics can tolerate temperatures from -30 to 85 °C, which supports transport and warehousing before the controller is placed into service. After installation, the unit should be operated only under its rated conditions so the feedback channel, power stage, and protective functions remain within their intended operating range.
