Product Description:

The DDS02.1-W050-DS53-00-FW is a drive controller built by Bosch Rexroth Indramat. It operates as a digital AC servo drive controller in multi-axis systems used for packaging, printing, and material handling lines, where it modulates power to matched motors and helps each axis respond accurately to motion commands. By using closed-loop control with position feedback, the unit maintains commanded speed and torque so the mechanical stage follows programmed profiles with stable tracking during starts, stops, and load changes. That behavior helps reduce drift and overshoot when the axis follows repeated positioning moves or changing speed commands.

Communication with higher-level PLCs occurs through the SERCOS interface, which exchanges command and status data in 1 ms cycles for coordinated motion across connected axes. Motor position enters the loop through digital servo feedback, allowing the controller to correct error at each sampling interval and keep response consistent during acceleration, deceleration, and constant-speed operation. The power stage can supply up to 50 A of continuous output to the motor windings, and heat generated by switching losses is removed by air from inside the control cabinet. For reliable operation, cabinet airflow should remain unobstructed so the cooling path is not restricted by nearby components or wiring.

The unit is part of Line 02 and is produced as Version 1, placing it within the second DDS design line and the first release of this configuration. It supports functions such as regenerative braking and parameter storage, which allow the drive to manage returned energy during deceleration and retain operating values within the controller. This controller fits systems that use synchronized servo axes over a common fiber ring, and its control structure is suited to applications that require repeatable motion, fast status exchange, and dependable diagnostics during routine machine operation. It is commonly used where multiple axes must remain coordinated throughout a production sequence.
