Product Description:
Bosch Rexroth Indramat manufactures the VT-HNC100-1-1X-110-1. It is a controller in the VT-HNC Digital Axis Controllers series that supervises a single hydraulic axis in automated machinery. By converting high-level NC commands into precise valve and sensor actions, the unit coordinates pressure, position, and velocity loops so that electrically driven sequences can be reproduced with hydraulic force. This operating role makes it suitable for hydraulic presses, injection units, and positioning stages that require repeatable motion control.
The analog front end provides 4 current input channels with an input resistance of 100 Ω ±0.2%, allowing differential transducers to be wired without additional shunts. Each channel is digitized to a resolution of 5 μA, giving fine feedback for pressure or force sensors. Position data from incremental encoders can be captured at up to 250 kHz, which supports fast linear axes without losing counts. Control algorithms and parameter sets reside in 1 MB of flash memory, so application data remains intact after power cycles. Four voltage input channels with 200 kΩ ±2% input resistance and 5 mV resolution share the same converter, while two current outputs and four voltage outputs generate reference signals to servo valves. This mix of input and output channels lets the controller process sensor signals and issue valve commands within the same hardware platform.
A PROFIBUS-DP interface communicates with the PLC backbone at up to 12 MBaud, and an RS-232 port is available at 9.6 kBaud for local access. The onboard MC68376 CPU uses a mixed 16/32-bit architecture, and its task scheduler uses 256 KB of battery-buffered RAM plus 8 KB of EEPROM for nonvolatile machine variables. Battery-buffered RAM supports retained working data, while EEPROM stores machine values that need to remain available between power cycles. Two current output channels, indicated by the value 2, deliver closed-loop drive commands. Four voltage outputs can operate auxiliary axes or proportional valves in the same control system.
