Product Description:

The DDS02.1-W050-DS01-02-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat in the DDS Drive Controllers series. In an automation cell, the unit regulates torque and velocity for matched servo motors, allowing coordinated motion over a standardized fiber-optic network. By acting as the electrical link between a motion control system and the mechanical axis, it supports closed-loop positioning while conserving cabinet space through its stack-mount housing. It converts drive commands into regulated motor current so the connected axis can accelerate, hold speed, and position accurately during automated cycles.

The controller can continuously supply a motor with 50 A of output current during sustained load periods. Command and diagnostic data are exchanged through the SERCOS interface, so time-synchronized control words and feedback telegrams can share a common optical ring with other devices. Heat generated by the power stage is removed by internal air cooling, with air drawn from inside the cabinet instead of through additional ducting. Rotor angle and velocity are returned to the drive through digital servo feedback, which supports high-resolution commutation without analog drift. This combination of optical communication and encoder-based feedback helps the drive maintain stable speed and position control during changing load conditions.

The unit belongs to Line 02, which indicates the mechanical format and connector arrangement used for this drive type. It carries Function ID 01, and the product is marked as Version 1. These identifiers distinguish the control function and product generation used on this model. The drive fits DDS-based multi-axis systems where consistent module layout and closed-loop servo control are required. They also help separate the control function from the power section within the DDS range.
