The Bosch Rexroth VT-HACD-1-1X/V0/1-D-0 (R901040277) is a sophisticated controller card designed to facilitate complex hydraulic control systems without the need for extensive programming knowledge. This versatile card is set up as a double-sided printed circuit board in European format, equipped with a microcontroller that oversees the entire process, including adjustments, connections, and closed control loops. All configuration data, command values, and parameters are stored non-volatilely in FLASH memory. The VT-HACD-1-1X/V0/1-D-0 is configured via software using a serial RS interface and the BODAC user interface for configuration, parameterization, and diagnostics. It offers two modes of operation: one that functions without bus capability and another that enables users to create custom motion sequences with available functional blocks. This controller card includes various signal linking options such as addition, subtraction, multiplication, division, minimum/maximum value generation, ratio calculation, and signal limiting. It supports analog I/O with inputs switchable between 0...10V and 4...20mA signals and an analog output switchable between 0...10V and 4...20mA. The digital I/O consists of several inputs and outputs with configurable functionalities. For precise motion control applications, the VT-HACD-1-1X/V0/1-D-0 can utilize digital position measurement systems like SSI or incremental encoders. It features a PIDT controller structure which can be tailored to act as P or PT controllers if needed. Additionally, it provides advanced functions for optimizing hydraulic system performance including direction-dependent amplification and characteristic curve correction. Error detection capabilities are comprehensive with monitoring for analog inputs range deviations, position sensor cable breaks, control errors when configured as a controller card among others. The front display allows for parameter adjustments and diagnostics but does not permit changes in configurations such as signal linking or trigger conditions. An optional valve output stage is available which works exclusively with PROFIBUS connection for WREX valves with two solenoids. Lastly, the BODAC PC program aids in configuring multiple control electronics connected via local bus without needing to reconnect serial interface cables constantly.
