The DDS02.1-A150-DA02-01 drive controller is produced by Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. Installed on a common backplane, it receives DC power from a separate supply module and sends three-phase output to a connected servomotor. In automated machining cells, pick-and-place gantries, and conveyor axes, the unit converts motion commands into controlled motor currents so each axis can follow the commanded profile with tight positional accuracy. This arrangement keeps the power supply stage separate from the axis control stage, which suits modular cabinet systems built around shared DC distribution.Setpoint values enter through the analog interface, allowing a host controller to send velocity or torque commands. This input method suits systems that use conventional analog command signals instead of a dedicated motion network. The current loop is closed with digital servo feedback, so the drive can process position and speed information directly from the motor feedback channel. The controller can deliver up to 150 A of continuous output current for medium-to-large synchronous motors. Thermal management uses external air from outside the control cabinet, which moves cooling air through the drive compartment to limit semiconductor temperature rise. The unit is part of Line 02 and is classified as a Digital AC Servo Drive Controller.The controller carries Function ID version 01 and design version 1. These identifiers set the applicable parameter group and align the module with earlier cabinet layouts. Because it operates from a shared backplane with a separate supply unit, the controller supports compact multi-axis arrangements without requiring an individual mains supply for each axis. Three-phase motor output and closed-loop regulation make it suitable for applications that need stable torque response and repeatable motion under changing load conditions.
