Rexroth VT-HNC100-1-22a/W-08-P-0 Electro-hydraulic Axis Controller

Product Description

VT-HNC100-1-22a/W-08-P-0 is Bosch Rexroth VT-HNC100 series single-axis digital hydraulic motion controller, used for closed-loop control of electro-hydraulic servo valves and proportional valves. It receives setpoint commands from upper PLC or CNC, collects feedback signals from magnetostrictive displacement sensors, LVDT or pressure sensors, and outputs drive signals to hydraulic valves to realize high-precision position, speed and force/pressure closed-loop control. Powered by 24VDC, equipped with CAN fieldbus and RS232 service interface, 08 represents 8mm housing width series, P stands for PROFIBUS DP communication option. DIN rail mounting, IP20 protection, operating temperature 0~+50°C. This is a discontinued legacy hydraulic axis controller, spare parts on market are new surplus or fully tested refurbished units.

Key Functions

• Single-axis cascaded closed loop: position loop, velocity loop and force/pressure control mode switchable
• Support LVDT, magnetostrictive sensor and analog feedback input ±10V
• Configurable servo valve / proportional valve output: ±10V voltage or ±20mA current signal
• Built-in motion profile generator, electronic cam, position synchronization and soft limit function
• Onboard CAN and RS232 service port, optional PROFIBUS DP for host system communication
• Full monitoring: sensor wire break, overtravel, controller hardware fault, overcurrent alarm
• Parameter configuration and diagnostic via WIN-PED software, online oscilloscope function
• Adjustable PID gain, ramp time, dead band and friction compensation for hydraulic non-linearity

Application Scenarios

• Metal forming machinery: hydraulic press, injection molding machine, die casting equipment
• Material test machines, fatigue test benches and hydraulic simulation test rigs
• Timber, paper and textile hydraulic automation production lines
• Hydraulic gantry, lifting and positioning equipment
• Retrofit replacement of old Rexroth HNC100 hydraulic control axes
