Rexroth VT-HNC100-1-23/W-08-P-0 Single Hydraulic Axis Digital NC Motion Controller with PROFIBUS DP

Product Description

VT-HNC100-1-23/W-08-P-0 belongs to Rexroth Indramat VT-HNC100 series, a dedicated digital NC axis controller optimized for electro-hydraulic proportional and servo valve closed-loop control, 

manufactured in Germany.

Model code breakdown:

VT-HNC100-1：Single hydraulic axis control

23：Hardware version 23 series

W：Wall-mounted metal housing

08：8-channel digital input/output terminal block

P：PROFIBUS DP fieldbus interface

0：Standard firmware without extra sensor options

Equipped with 32-bit MC68376 industrial processor and professional hydraulic control algorithms, it realizes high-precision position, speed, pressure and force composite closed-loop 

control for hydraulic cylinders, built-in friction compensation, valve dead zone correction and vibration suppression to eliminate hydraulic hysteresis.

It supports incremental encoder and SSI absolute transducer position feedback, outputs ±10V / 4–20mA signals to drive hydraulic servo valves. The front PROFIBUS DP DB9 port connects 

upper PLC for real-time data exchange, while RS232 debug port works with WIN-PED software for programming, parameter calibration and fault diagnosis.

All field signals adopt galvanic isolation to resist EMI and ground loop interference. The unit features passive convection cooling and conformal coated PCB, widely used as maintenance spare 

for hydraulic presses, injection molding machines, material test benches and heavy-duty fluid power automation lines.
