Product Description:

The 0 608 760 108 servo amplifier module is built by Bosch Rexroth Indramat within the LTU Servo Amplifiers series. Designed for cabinet-mounted drive systems, the unit converts a fixed DC link into a regulated three-phase supply for servo motors used in positioning, packaging, and assembly cells. By controlling motor current and frequency, it provides the closed-loop torque needed by digitally commanded axes in industrial automation. Its backplane connector supports integration into multi-axis racks where several amplifier channels share one installation space. This arrangement also suits dense control cabinets that use a common rack structure for power and signal distribution.

The amplifier draws an input current of 10 A from a DC bus maintained at 330 V. This operating range sets the load that the internal power stage can handle without derating. The steady current draw helps stabilize the common bus during rapid load shifts, while the DC topology removes the need for an integrated rectifier and lets several axes share one supply. Because the module uses a shared intermediate circuit, the supply section can be centralized instead of repeated on each axis. The 330 V level keeps conduction losses low in the IGBT bridge and remains compatible with standard intermediate circuits, while cabinet airflow carries heat away from the power stage.

On the motor side, the converter supplies up to 10 A of output current across a frequency span of 0–100 Hz as a symmetrical three-phase waveform at approximately 230 V. This combination supports low-speed torque regulation as well as near-rated speed operation for typical 200 V class servomotors. Its voltage and frequency range make it suitable for servo tasks that need both controlled starting torque and steady running speed. At just 2.840 kg, the compact module fits beside other channels without adding much load to the panel structure. The output stage provides a controlled AC supply from the shared DC source, which helps the motor respond smoothly during acceleration, deceleration, and position changes.
