Product Description:

The DDS02.1-W100-DA03-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It mounts beside the supply module in a control cabinet and channels DC-bus energy to a compatible servo motor according to commands from the motion processor. By regulating current and voltage in real time, the unit supports closed-loop position, speed, and torque control on packaging stations, pick-and-place gantries, and material-handling axes. Its modular housing also allows multiple drives to share a common mounting arrangement and bus connection within the same cabinet assembly. This layout helps keep multi-axis cabinets organized when several servo axes are installed side by side.

In operation, the controller can supply up to 100 A of phase current, which sets the available current capacity for the connected motor. Command data enter through an analog interface, allowing velocity or torque setpoints from a PLC analog output card without protocol conversion. Thermal management relies on internal air cooling, so cabinet air moves across the heat sink instead of requiring external ducts. This arrangement removes heat from the power stage during normal operation. Rotor position is returned as digital servo feedback, allowing the drive to process encoder signals directly for closed-loop control. The assigned identifiers Function ID 01 and Line 02 place the unit in the corresponding DDS function group and product line.

The control code is supplied as a separate subitem, so the operating software is ordered independently of the hardware. After installation, the controller identifies itself as Version 1. The unit uses the software revision assigned to this drive type. Because the software is separate from the main hardware assembly, updates can be made without changing the cabinet wiring or the physical position of the drive. This arrangement keeps the electrical installation unchanged when only the software portion of the unit needs to be replaced or updated.
