Product Description:

The VT-HACD-3-2X-E-I-00-001 is an axis controller produced by Bosch Rexroth Indramat within the VT-HACD Digital Axis Controllers series. It manages hydraulic or electromechanical motion by coordinating closed-loop control tasks and field network communication inside industrial automation cells. By combining signal conditioning, program execution, and network routing on one compact card, the unit replaces multiple discrete interface boards and simplifies cabinet wiring.

This controller provides 6 analog inputs that accept position, pressure, or velocity feedback, and each channel is digitized with 5 mV resolution for fine loop tuning. Command signals reach the drive layer over an EtherNet/IP bus interface that is connected through two switched RJ45 ports, allowing line or ring network topologies. Internal electronics draw only 200 mA from a 24 VDC control supply, reducing heat generation in densely populated racks. For Boolean logic, the board carries 9 digital inputs and 8 digital outputs, supporting interlocks, status lamps, and valve solenoids without external relays.

The sourcing outputs can deliver up to 20 mA per channel, and a watchdog cuts them off if the control system registers a fault. Motion algorithms run on a 32-bit PowerPC processor that also handles cyclic data exchange with the incremental encoder interface rated for 250 kHz counting frequency, so high-speed axes retain precise position capture. An SSI channel over RS-485 supports absolute transducers up to 28 bits. Electrical components are housed in an IP20 card frame that weighs 1162 g and slides into a standardized Eurocard carrier. Two Ethernet ports permit daisy-chain wiring, while three analog outputs supply ±10 V reference signals for proportional valves. A dedicated reference voltage rail of +10 V ±25 mV is available for sensor excitation.
