Product Description:

The DDS03.1-W030-DA02-00 is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. It serves as the axis amplifier between a machine’s PLC and its servo or induction motor, translating velocity or torque commands into controlled three-phase power. In industrial automation cells such as pick-and-place modules, form-fill-seal equipment, and palletizing stations, the unit maintains closed-loop motor performance so that loads follow programmed motion profiles with repeatable precision during starts, stops, and speed changes. That operating role makes it suitable for machine sections where smooth acceleration and stable speed regulation are required throughout a repetitive duty cycle.

Signal exchange with the device uses an analog interface, so ±10 V references from legacy motion cards can command the axis without additional fieldbus hardware. This allows the controller to integrate with existing control hardware that still relies on analog command architecture instead of network-based motion communication. Thermal energy is removed by internal air cooling, with cabinet air moving across the heat sink instead of requiring external ducting. The power stage delivers up to 30 A of continuous current for sustained motor operation. All live parts are behind terminals rated to IP20, so the unit is intended for installation inside closed electrical enclosures. Reliable operation is permitted at ambient temperatures from 0 to 45 °C, and no output derating is required until the installation exceeds 1000 m above sea level.

Motor position and velocity feedback enter the controller through digital servo feedback, allowing the drive to process rotor data directly for stable speed regulation and accurate positional response. This arrangement supports responsive axis behavior without requiring a separate external feedback processor. The unit belongs to Line 03 of the platform and is supplied as Version 1. During transport or extended shutdown, the electronic components remain stable in environments from -30 to 85 °C, so the drive can be stored under typical indoor warehouse conditions without damage from normal temperature variation.
