Product Description:

The DDS03.1-W030-DS04-01 is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It converts DC-bus energy into regulated three-phase output for a compatible servo motor. The drive also performs closed-loop current and velocity control so connected servomotors can follow motion commands accurately in automated assembly lines, packaging machines, and material-handling axes. This operating role lets the controller serve as the power and regulation stage for coordinated motion systems.

This controller exchanges real-time setpoint and diagnostic data over the SERCOS interface, allowing deterministic fiber-optic communication with the master PLC and synchronized command updates during operation. A continuous output capability of 30 A supports medium-power motor windings without derating under the stated operating conditions. Thermal management uses internal cabinet air, so the unit relies on airflow from the enclosure rather than an onboard fan. The housing carries an IP20 protection category, so it must be installed inside a control cabinet that prevents direct contact with live parts. Position and speed loops are closed with digital servo feedback, ensuring high-resolution incremental data exchange between the motor encoder and the drive for precise axis regulation.

The unit operates reliably between 0–45 °C, and full current is available within this ambient range without separate forced cooling at the drive itself. For storage or transport, it withstands temperatures from -30 to 85 °C, helping protect electronic components during warehouse handling or inactive periods. Installation is approved up to 1000 m above sea level, which suits standard cabinet rooms or mezzanines without altitude compensation. The unit is part of Line 03. Nonvolatile memory retains parameter data when control power is removed.
