Product Description:
The VT-HACD-1-15-V0-1-0-0 is a plug-in card axis controller from Bosch Rexroth Indramat's VT-HACD Digital Axis Controllers series. It coordinates hydraulic or electric actuators by processing multiple feedback channels and generating proportional valve commands in distributed automation cells. Installed on a 100 × 160 mm Eurocard, the module occupies little cabinet space while adding closed-loop position, velocity, and pressure control to motion sequences driven by a supervisory PLC.
This controller operates from a nominal bus of 24 VDC, and it monitors up to 6 analog input channels with a leakage error of only 0.15 %, supporting stable sensor scaling. Current-mode inputs have 100 Ω of resistance and resolve down to 5 µA, so low-level transducer signals can be interpreted without external conditioning. Each program cycle completes within 2 ms, allowing tight loop gains even on fast hydraulic axes. Command information is sent through the first analog output, which can source up to 10 mA; this current margin is adequate for direct drive of most proportional valve coils without auxiliary amplifiers.
The digital section supplies field devices through outputs rated at 30 mA per channel, and onboard protection is provided by a time-delay fuse of 4 A to withstand inrush events without nuisance trips. Distributed installations are supported by a local bus that may run as far as 280 m from the master, maintaining deterministic telegram timing across large machinery. When the axis is inactive, the electronics draw only 250 mA, limiting heat rise inside sealed enclosures. Three analog outputs share a 14-bit resolution of 1.25 mV, giving fine command granularity for pressure or speed reference voltages. With a mass of 0.2 kg, the card is easy to handle, and its compact profile simplifies dense rack layouts where multiple motion channels are required.
