Product Description:
The VT-HNC100-1-1X-230-8 digital axis controller is produced by Bosch Rexroth Indramat within the VT-HNC Digital Axis Controllers series. Designed for electro-hydraulic motion loops, it interprets numerical setpoints, closes position or pressure feedback, and supplies drive commands so that a single hydraulic axis follows the desired trajectory in presses, test rigs, and material-handling machines. By concentrating the closed-loop logic inside the panel, it frees the supervisory PLC from high-speed tasks. This arrangement helps the machine respond quickly to changing hydraulic conditions while the higher-level control handles sequencing and coordination.
Its configuration targets control of 1 hydraulic axis, so all processing resources are dedicated to that motion channel. The analog front end offers 4 current input channels, each able to read ±20 mA transducer signals, while 2 current output channels generate proportional valve currents. Four high-impedance inputs help prevent connected sensors from being loaded by the controller circuitry. Encoder pulses are accepted at rates up to 250 kHz, which supports fine feedback resolution even when the axis is moving quickly. Command generation uses a ±10 V ±25 mV reference, providing predictable centering for directional valves and pump controllers.
Logic integration is expanded through 8 digital inputs for limit switches and interlocks and 8 digital outputs for status or safety chains. Four voltage input channels and four voltage output channels provide additional analog connectivity for supporting devices that do not use current-loop signaling. Non-volatile storage totals 1 MB of flash memory, assisted by 256 KB of RAM for real-time data and an 8 KB EEPROM for retained parameters. Communication with higher-level devices is handled through an RS-232 link at 9.6 kBaud, and absolute position data can arrive through a 28-bit SSI interface. The enclosure measures 71 × 155 × 204 mm and weighs 1.0 kg, and the unit belongs to component series 1 within the HNC100 product line.
