Product Description:

The DDS03.1-W050-RA01-02-FW is a servo amplifier module manufactured by Bosch Rexroth Indramat in the DDS Drive Controllers series. This module occupies a slot in multi-axis systems where a central motion controller issues command voltages and the DDS unit shapes power for individual motors. By processing setpoint signals and regulating output phases, it supports coordinated positioning, speed control, and torque regulation on automated lines, gantries, and packaging cells. The amplifier is intended for systems that divide machine motion across separate axis modules while keeping command generation at the control level.

The drive delivers a continuous current of 50 A, giving it enough capacity to run medium-frame Indramat servomotors in continuous operation. Command data enter through an analog interface, allowing ±10 V velocity or torque references to be sent directly from PLC motion cards. Thermal management relies on internal air cooling, so cabinet air moves across the heat sink without the need for rear exhaust ducting. Rotor position is returned through resolver feedback, allowing the drive to process sinusoidal signals for speed and position evaluation. The unit carries Function ID 01, which identifies the assigned operating format for this controller. It also belongs to Line 03, placing it within the third design line of the DDS platform.

The unit is Version 1. As a Digital AC Servo Drive Controller, it handles parameter processing, diagnostics, and current-loop control with onboard signal processors instead of external analog circuits. Application code is stored in removable memory, so the software can be selected for the axis type and required operating mode. This arrangement supports the expected response timing and protective behavior for analog command operation and resolver-based motor feedback. Because the memory is removable, software changes do not require changes to the power section or feedback hardware.
