Bosch Rexroth VT-HNC100-1-23W-08-0-0
Technical Specifications: Part number: VT-HNC100-1-23W-08-0-0 Power supply: 24VDC Control: Single hydraulic axis Feedback input: LVDT, potentiometer, ±10V analog, 4-20mA Output: Analog command for proportional valve Communication: Serial service interface, field bus interface Operating temperature: 0℃ to +55℃ Protection class: IP20 Mounting: Eurocard rack plug-in card
Functional Features: Digital closed-loop control for single hydraulic axis. Selectable control modes: position, velocity, force and pressure regulation. Support multiple types of position and pressure feedback sensors. Adjustable control gain, ramp and limit parameters via service software. Built-in signal monitoring for sensor wire break and signal anomaly. Fault memory to store error events for maintenance diagnosis. Analog output for proportional valve drive. LED status indication for operation and fault.
Application Scenarios: Single axis hydraulic press, hydraulic bending machine, hydraulic test bench, injection molding machine hydraulic axis, material tensile test equipment, small hydraulic forming machine.
Performance Parameters: Fast closed-loop calculation cycle for hydraulic actuator dynamic response. High positioning repeatability under static and dynamic load. Configurable filter to suppress sensor signal noise. High stability for continuous machine operation.
Material Composition: FR4 industrial printed circuit board. Microprocessor, ADC and DAC chips. Analog signal conditioning circuits. Signal isolation components. Flame retardant plastic front panel. Gold-plated edge connector for rack backplane. Screw terminal block for field wiring.
Structural Features: Eurocard standard plug-in board design. Front panel with LED indicators and service communication port. Edge connector connects to rack backplane for power supply. Front screw terminals for sensor and proportional valve wiring. Hardware jumpers for basic signal configuration. Isolation layout between low level feedback and valve drive circuit.
Working Principle: After 24VDC power on, the controller initializes stored axis parameters. Setpoint command is received from upper automation controller. Feedback signals from LVDT or pressure transducer enter the card, converted to digital value. The processor calculates control deviation and outputs analog command signal to proportional valve. The proportional valve adjusts hydraulic flow to move hydraulic cylinder. Onboard diagnostic circuit checks feedback signal continuously and records fault information when abnormality occurs.
Installation Requirements: Install controller card in matching Rexroth rack slot. Use shielded twisted pair cable for sensor and valve wiring. Separate analog signal cables and high voltage power cables. Tighten terminal screws to specified torque. Install in IP20 control cabinet. Complete protective earth bonding for rack.
Usage Notes: Save parameter backup before card replacement. Check feedback sensor wiring polarity during commissioning. Tune control gain carefully to avoid hydraulic oscillation. Cut rack power before plugging or unplugging the controller card. Verify emergency stop interlock function before machine trial run.
