The Bosch Rexroth VT-SR7-1X/0/A4VS.180HS SO43A-1608 (R978918867) is a sophisticated amplifier designed for precise control of variable displacement axial piston pumps in hydraulic systems. This component features a push-pull output stage with bipolar transistors, capable of being connected or disconnected via an enable circuit relay, with the enable status indicated by an illuminated LED on the front plate. The amplifier includes an I controller with an integrated dither signal generator, where the amplitude of the dither signal is adjustable. For precise actuation, it utilizes a PD controller to manage the prestage current command value, while also providing real-time current value feedback through an instrument display on the front panel. The unit's oscillatordemodulator is essential for accurate position sensing and comes as a pluggable printed circuit board tailored to match the specific size of the axial piston unit. The PD controller receives both position command value and actual position value inputs, with its D share impacting only velocity feedback from the actual value. Users can adjust the zero point from the front plate for calibration purposes. The device requires a symmetric operating voltage which is safeguarded against reverse polarity; if voltage regulators are not present on the board, an additional stabilized auxiliary voltage is necessary. Optionally available is a PID controller modification that allows for additional control loop integration such as drive control; this feature necessitates customer-specific configuration during ordering. These amplifiers are uniquely identified upon delivery due to this customization. The VT-SR7-1X/0/A4VS.180HS SO43A-1608 operates within component series X in Eurocard format and excels in adjusting flow for AVS...HS series variable displacement axial piston pumps, ensuring optimal performance and reliability in hydraulic applications.
