Product Description:

The DDS02.1-A100-DS04-01 is a servo drive controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. It is installed in multi-axis automation cells to modulate power to synchronous or asynchronous servo motors. This allows commanded speed, torque, and position profiles to be followed with high repeatability on assembly lines, packaging stations, and material-handling gantries. It regulates motor current as motion demands change, helping the connected axis remain stable during indexing, speed changes, and positioning tasks. The controller is suited to machines where several axes operate from a shared automation platform.

For networked control, it carries a SERCOS interface, allowing fiber-optic real-time communication between the drive and the master controller. The power stage is rated for up to 100 A, giving the axis headroom for rapid acceleration without overloading the internal IGBTs. Enclosure protection is limited to IP20, so the unit must be mounted inside a closed cabinet. Thermal energy is removed by external cabinet air cooling, which draws ambient air across the heat sink to keep semiconductor junctions within limits. Reliable operation is specified for ambient temperatures from 0 to 45 °C, matching standard shop floor conditions. Real-time communication also supports coordinated command updates across multiple axes.

The control loop relies on digital servo feedback, which supplies high-resolution rotor position data for precise current vector calculation. This feedback lets the drive close the speed and position loops directly at the controller. Installations are permissible up to 1000 m elevation, beyond which derating of the power section is required because of reduced air density. During storage or transport, electronic components withstand a non-operating range of -30 to 85 °C without degradation of insulation or electrolytic capacitors. The unit carries Function ID Version 01, while the hardware is in Line 02 and Version 1.
