Product Description:

The VT-HACD-B1-1X-V0-1-0-0 is a plug-in digital axis controller card produced by Bosch Rexroth Indramat and included in the VT-HACD Digital Axis Controllers series. Installed in hydraulic or electromechanical motion systems, the board supervises one closed-loop axis by processing setpoint commands, sensor feedback, and amplifier signals to regulate position or velocity. This arrangement lets the controller compare command values with actual feedback in real time and correct deviations before they affect machine motion. As a compact Euro-card, it slides into modular automation racks and supports centralized axis control with minimal external wiring.

Its physical outline measures 100 x 160 mm, and that size, together with the Euro-card format, allows installation in standard card cages. Mechanical compatibility is supported by the DIN 41494 backplane standard, so the board fits industrial housings that use the same guide rails and connector layout. Signal and power paths are routed through a single 64-contact strip, which keeps the faceplate clear for diagnostics and access. The control electronics operate from a stabilized supply of 24 VDC, and the integrated output stage delivers regulated pulsed current to proportional valves or servo amplifiers for accurate axis response.

A small front display presents status codes and parameter numbers for local setup, while a bidirectional RS-232 port allows a computer to exchange parameter sets and trace data over a direct serial connection. For absolute position feedback, the controller interprets SSI signals, supporting repeatable positioning in hydraulic axes that use linear transducers or rotary encoders with serial synchronous output. This feedback method is useful when the application must recover an exact position reference after a power cycle. Off-line tuning is handled through the Windows-based BODAC program, which reads configuration files over the same serial link and stores them in nonvolatile memory.
