Product Description:

The DDS02.1-W050-DS03-02-FW/S100 is a digital AC servo drive controller built by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. In an automation cell, this drive forms the intermediary between the motion controller and the motor, converting command words into precise current pulses that govern shaft position and velocity. By processing command data and motor feedback in one housing, the unit supports closed-loop motion with stable speed regulation and accurate axis response during repeated machine cycles. This control method suits servo applications that require repeatable positioning and coordinated movement.

Communication with the host is carried over the SERCOS interface, a fiber-optic link that synchronizes multiple axes on a 62.5 µs cycle. The drive can deliver up to 50 A of continuous output current, allowing it to run medium-power servomotors without derating. Heat generated by the power electronics is expelled through internal air cooling, so cabinet air moves through the heat sink instead of relying on an external blower. The front wiring zone has an IP20 rating that helps guard against accidental contact with live parts in panel-mounted installations. Reliable closed-loop operation is supported by digital servo feedback, which allows the controller to track motor position accurately over the full travel range. All functions remain available within an ambient temperature range of 0–45 °C, which fits typical industrial enclosures.

For installation planning, the drive can operate at elevations up to 1000 m above sea level before cooling conditions begin to change. During transport or offline storage, the electronics can withstand temperatures from -30 to 85 °C, which helps protect the unit when it is moved between different environments. The controller is part of Line 02 and is built to version 1, providing clear revision information. Application software is ordered separately so the unit can be matched to the requirements of the machine where it will be installed.
