Product Description:
Bosch Rexroth Indramat produced the VT-HNC100-1-1X-131, a member of the VT-HNC Digital Axis Controllers series and the Digital NC Control HNC100 product line. Supplied as component series 1, the unit supervises a single hydraulic axis and provides closed-loop position or pressure control in presses, molding machines, and test rigs. Installed in a control cabinet, it converts motion commands from a PLC into precisely metered valve currents while reading analog transducer signals for real-time correction. This type of controller is used where hydraulic response must be adjusted continuously to follow changing load conditions.
The controller is supplied in a version for 1 hydraulic axis, which enables all internal control loops for one cylinder. A 16/32-bit MC68376 microcontroller handles interpolation and internal checks. Application code and parameter blocks are stored in 1 MB of Flash, fast variables use 256 KB of RAM, and calibration constants are kept in 8 KB of EEPROM. This memory arrangement separates the control program, temporary process data, and stored calibration values. Four differential voltage inputs, four current inputs, and four impedance inputs collect feedback signals, while four voltage outputs and two current outputs drive valves or auxiliary devices.
Power consumption stays below 8 W, which helps limit heat inside the cabinet and reduces the load on the control power supply. The analog section maintains accuracy with a current input resistance of 100 Ω ±0.2 % and a voltage input resistance of 200 kΩ ±2 %; current outputs can drive coil loads up to 500 Ω, and the voltage outputs remain linear with loads above 1 kΩ. These electrical values suit common sensor circuits and proportional valve interfaces used in hydraulic systems. Setup and service are handled through an RS-232 link operating at 9.6 KBaud, so parameter sets can be uploaded or archived without disconnecting the wiring.
