Product Description:
The VT-HNC100-1-1X-120-4 is a digital axis controller produced by Bosch Rexroth Indramat and assigned to the VT-HNC Digital Axis Controllers series. This model belongs to the HNC100 product group and is supplied as component series 1. It provides closed-loop control for one hydraulic axis, enabling pressure or position regulation in presses, test rigs, or molding machines through coordinated analog and serial interfaces. It is intended for machine applications where a single hydraulic axis must respond consistently to changing process demands.
The controller is configured for 1 hydraulic axis, and its analog section offers four voltage and four current input channels plus two current and four voltage outputs for valve or sensor interfacing. A 16/32-bit MC68376 processor executes interpolation tasks, while volatile memory includes 256 KB of RAM for runtime data. Nonvolatile storage includes 8 KB of EEPROM for parameters and 1 MB of Flash EPROM for application tables and stored operating data. Total internal consumption remains below 8 W, so the unit can be powered from the control cabinet’s low-voltage supply without forced cooling. This memory arrangement lets the controller retain parameter data after power loss while keeping active calculation data available during operation.
The analog section has a current input resolution of 5 µA and a voltage input resolution of 5 mV, allowing fine adjustment of servo valves and transducers. Input impedance is 100 Ω for current loops and 200 kΩ for voltage signals, which helps limit loading on connected devices. Each voltage output can source or sink up to ±10 mA, and the two current outputs provide programmable ±10 mA ranges. Serial diagnostics use an RS-232 interface set to 9.6 kBaud, while absolute position data can be accepted through an SSI port with a width of 28 bits. That combination supports accurate scaling of command signals and sensor feedback in hydraulic loops that depend on stable analog behavior.
