Product Description:

The DDS02.1-W050-DL04-00 is produced by Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. It functions as a closed-loop power stage that converts DC bus energy into phase-accurate AC output for an attached servo motor. This supports coordinated positioning and speed control in automated assembly cells, printing lines, and robotic equipment. By combining amplifier electronics, logic, and protective circuits in one housing, the unit reduces external wiring and lets a higher-level PLC command motion directly through the drive. It is suited for servo applications that require repeatable response over frequent start, stop, and direction-change cycles.

The drive is rated for a continuous output of 50 A, allowing the connected motor to sustain demanding load conditions without immediate thermal derating. Heat is removed by internal air cooling, so cabinet air is circulated through the unit instead of relying on an external blower. As a Digital AC Servo Drive Controller, it processes reference commands and delivers sinusoidal motor current that helps keep torque production smooth. Command exchange is handled through single-axis position control, which allows the higher-level controller to send target positions or speeds rather than raw analog signals. This control method is appropriate for installations where one drive manages one motor axis with direct motion commands from the machine controller.

Actual rotor angle is returned through digital servo feedback, supporting fast current regulation and short position-update intervals during closed-loop operation. The feedback channel also lets the drive correct speed and position errors quickly when load conditions change during acceleration or deceleration. The unit is part of Line 02, which uses the corresponding mechanical size and connector arrangement for this design line. It is built as Version 1. In multi-axis cabinets, the controller can operate beside compatible modules on a shared DC bus and common cooling path, which helps keep rack installations compact.
