Product Description:

The VT-HNC100-2-2X-M-16-P-0 is a digital axis controller produced by Bosch Rexroth Indramat for the VT-HNC Digital Axis Controllers series. It serves as the command center for hydraulic motion loops by calculating setpoints and closing position or force feedback for servovalves and cylinders. By combining fieldbus communication with onboard I/O, the unit helps presses, plastic machines, and test rigs coordinate two hydraulic axes with a predictable response.

This version supports up to 2 hydraulic axes and exchanges real-time data over a DP Profibus interface. The network can run at speeds up to 12 MBaud, allowing fast transfer of target values and diagnostic data to a supervisory PLC. Core calculations are handled by a MC68376 (16/32-bit) processor with 256 KB of battery-backed RAM, while long-term parameters are stored in a 1 MB Flash EPROM. Four differential voltage inputs accept feedback devices, matching current inputs handle transmitters with 4–20 mA signals, and two current outputs drive proportional valves. A serial RS-232 port operates at 9.6 kBaud for setup and diagnostics, and power consumption remains limited to 8 W for cabinets with restricted thermal capacity.

The controller provides 16 input/output channels for fast sequencing tasks and mounts in a standard 19-inch rack with its dedicated carrier. Its physical dimensions are 106.5 x 155 x 204 mm, and the installation weight is only 1.2 kg. The unit also includes 4 voltage outputs for actuator command. An inductive position sensor is not integrated, so external LVDT or magnetostrictive transducers must be connected to the available channels. This layout gives the controller separate signal paths for feedback, valve control, and discrete machine functions without adding external interface modules for basic loop operation.
