Product Description:

The VT-HNC100-1-22/W-24-0-0 is a digital axis controller produced by Bosch Rexroth Indramat within the VT-HNC Digital Axis Controllers series. It is classified as component series 2 and is configured for one hydraulic axis, so it performs closed-loop motion or pressure control for a single cylinder or hydraulic motor in industrial machinery. The housing is intended for cabinet installation by wall mounting, and this model is supplied without a bus connection, so integration is handled through conventional analog and discrete wiring. Internally, it follows the Digital NC control HNC100 architecture used across the platform.

Four differential current inputs accommodate valve feedback, and a 100 Ω ±0.2% shunt digitizes them with a resolution of 5 µA. The board also includes four voltage inputs with 200 kΩ ±2% impedance, sampled in steps of 5 mV. Two current outputs and four voltage outputs drive servo valves or provide reference signals. A 16/32-bit MC68376 microcontroller executes the control loops, while an incremental encoder rate of 250 kHz and an SSI width of up to 28 bits support high-resolution feedback devices. The controller draws only 8 W from the 24 V supply, which helps limit cabinet heat.

To coordinate machine sequences, the device provides 24 input/output lines for sensor, interlock, and drive-enable signals without requiring extra interface cards. Parameter sets, cam tables, and user routines fit into the 1 MB flash area, while 8 KB of EEPROM preserves calibration data and 256 KB of RAM supports cycle computation. The housing measures 106.5 × 155 × 204 mm and weighs 1.2 kg, so it occupies little panel space. No inductive position sensor is included, so external SSI or incremental transmitters must be supplied for feedback. This arrangement allows the controller to manage pressure, position, and velocity loops in demanding hydraulic axis applications.
