Product Description:

The DDS02.1-W150-RS03-03-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat and delivered within the DDS Drive Controllers series. In an automation cell, it supplies regulated three-phase power to matched synchronous or induction servo motors. It also exchanges position data with a higher-level controller and executes closed-loop speed and torque commands that keep motion axes synchronized with machine cycles. This makes it suitable for coordinated motion tasks such as material handling, indexing, and other applications where axis response must remain consistent during repeated production sequences. Its role is to convert incoming power into controlled motor current while responding quickly to changing motion commands.

The drive communicates through a SERCOS interface, permitting deterministic fiber-optic data exchange for synchronized axis control. During normal operation, it can deliver a continuous output of 150 A, which is the maximum current the attached power electronics can sustain without thermal derating. Protection against accidental contact is provided by an IP20 housing, so the unit must be mounted inside a control enclosure. Heat is removed by forced convection using air from inside the control cabinet, which simplifies ducting but requires adequate cabinet airflow around the heat-producing components. Reliable operation is permitted between 0 to 45 °C, provided the enclosure stays within that temperature range.

Feedback from the attached motor is processed with resolver feedback, which supports stable position detection in electrically noisy environments and helps the drive maintain accurate control during speed changes. When the machine is idle, the unit can withstand ambient storage temperatures of -30 to 85 °C without damage to its power modules or control logic. Installation sites can be located up to 1000 m above sea level before extra cooling or output reduction becomes necessary. The unit is Version 1, matching the designated revision for this drive type.
