Product Description:

The Bosch Rexroth Indramat VT-HNC100-4-3X-N-I-00-G04 is a digital axis controller in the VT-HNC Digital Axis Controllers series. It governs hydraulic servo valves and cylinders in multi-axis machinery, converting numerical setpoints from a higher-level PLC into synchronized motion commands. By integrating closed-loop control, the unit maintains position, speed, or pressure on each hydraulic axis. The controller processes incoming feedback continuously so the machine can correct deviations as load conditions change during a cycle. That operating role makes it suitable for presses, transfer systems, test stands, and other equipment that depends on coordinated hydraulic movement across more than one controlled axis.

Dedicated hardware on this version supports 4 hydraulic axes, letting a single controller supervise multiple actuators without additional cards. The encoder inputs provide a regulated supply of 5.25 V ±1%, which matches typical TTL and RS-422 feedback transducers while helping maintain stable signal quality. Each channel can capture incremental pulse trains up to 250 kHz, so high-resolution encoders can be read during rapid strokes. Command outputs reference a stable +10 V ±25 mV, giving symmetric analog drive signals for proportional valves. The housing has an IP20 rating, so the controller is finger-safe at the terminals and is intended for installation inside a cabinet.

Within the manufacturer's internal numbering, the controller belongs to component series 3, placing it among later HNC versions with the same general diagnostics structure. SSI position feedback can be accepted up to 28-bit resolution, allowing absolute encoders to report fine angular or linear increments without losing detail in the controller. It belongs to the broader Digital NC control HNC100 platform, which keeps the operating concept consistent across related units. Because the device is supplied without a bus connection, integration relies on analog references and discrete I/O for communication with the surrounding machine controls.
