Product Description:

The DDS03.1-W050-RA02-01 is a servo drive controller assembled by Bosch Rexroth Indramat for integration into the DDS Drive Controllers series. Positioned on a backplane next to its power supply module, it converts motion commands from supervisory PLCs into regulated current and voltage for servo motors in modular multi-axis systems. By executing closed-loop control in real time, it maintains precise position, speed, and torque profiles required by automated assembly stations, pick-and-place gantries, and packaging equipment. This arrangement lets the unit serve as the regulation stage between the machine control and the connected motor.

An analog interface provides ±10 V command and enable lines so the unit can be driven by legacy or open-loop motion cards without additional conversion hardware. The power stage is dimensioned for a continuous motor output current of 50 A, giving adequate headroom for medium-frame actuators that experience short acceleration peaks during repetitive cycles. Heat generated in the IGBT bridge is removed by internal air cooling, which draws cabinet air across the heat sink and avoids external ducting. Rotor position is resolved through resolver feedback, allowing the control loop to maintain full torque at zero speed even in electrically noisy environments. The unit carries Function ID 01, which identifies the control profile used by this drive type.

The hardware belongs to line 03, so it accepts option cards and bus modules standardized for this subset of the series. The unit is a Digital AC Servo Drive Controller and is suitable for synchronous or induction motors supplied from a common DC bus in coordinated motion systems. It is released as Version 1. By occupying only a single slot in the control cabinet and sharing a backplane airflow path with adjacent drives, the device supports densely packed multi-axis racks without additional thermal hardware.
