Product Description:

The DDS02.1-A150-DA02-01 is a digital AC servo unit manufactured by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. Installed in a multi-axis rack, it receives motion references from a master control and converts them into synchronized voltage and current for servo motors. Its role in industrial automation is to regulate acceleration, speed, and holding torque so packaging stations, conveyor modules, or machining axes maintain repeatable positioning accuracy. It is commonly used where coordinated motion depends on accurate response to reference changes and repeatable axis behavior over long production runs.

Communication with the machine PLC is handled through an analog interface, so speed or torque commands can be transmitted as ±10 V signals or 4–20 mA loops. Thermal management relies on external air cooling, with ambient air from outside the control cabinet passing over the internal heat sink to remove switching losses. The power section is rated for a continuous output of 150 A, enabling the drive to supply larger Indramat motors without immediate current limiting. Closed-loop operation uses digital servo feedback, which returns position data over a high-speed serial channel to reduce following error during changing load conditions. The controller is part of Line 02, which sets the backplane dimensions, bus rail alignment, and connector placement within a DDS rack. This arrangement helps the unit fit properly beside other modules in the same drive assembly.

The unit carries function ID 01 and is built as Version 1. It is classified as a Digital AC Servo Drive Controller and combines the power stack, gate drivers, feedback reader, and integrated logic board in one housing. Keeping these sections together shortens internal signal paths and helps keep cabinet wiring compact. The housing processes command input, power conversion, and motor feedback without requiring separate external control hardware for those core tasks. This layout suits rack systems where neighboring modules share power distribution and limited panel space.
