Product Description:
The VT-HNC100-2-31/P-I-E0/000 is a digital axis controller produced by Bosch Rexroth Indramat within the VT-HNC Digital Axis Controllers series. It governs hydraulic motion by issuing analog and digital commands to proportional valves while reading sensor feedback in real time. Installed inside a machine control cabinet, the device provides centralized control for synchronized pressure, speed, and position loops. These capabilities support electrohydraulic equipment such as presses, injection-molding machines, and other automated systems that require coordinated hydraulic movement.
The controller supports two hydraulic axes, allowing it to supervise two independent servo loops. It provides four current input channels for pressure or force sensors and two current output channels for driving proportional valves. A total of 22 digital I/O channels accommodates limit switches, status signals, valve enables, alarms, and pump commands, with as many as 20 lines configurable as outputs. An encoder auxiliary rail supplies +24 VDC, while a separate logic rail supplies +5 VDC for incremental encoder connections. Two encoder channels accept direct position feedback from compatible devices. Four voltage inputs and four voltage outputs process ±10 V analog signals for command and feedback functions. The controller belongs to component series 3 and is supplied without a bus connection.
The controller uses top-hat rail mounting, allowing it to be secured inside a protected control cabinet. Its compact IP20 enclosure protects against accidental contact with internal components but requires an external cabinet for additional protection. A regulated power source must keep supply ripple below 1.5 V peak to peak, and control power enters through a three-pin connector. A nine-pin RS-232 port provides direct access for configuration and diagnostic tasks when no fieldbus is installed. External transducers can receive power from the dedicated 24 VDC sensor supply. Differential analog paths use a +10 VDC reference to maintain consistent signal measurements across connected devices. The controller does not include an inductive position sensor, so position data must come from the available encoder or analog feedback channels.
