Product Description:

The VT-HNC100-2-3X-E-I-00-G02 is a digital axis controller produced by Bosch Rexroth Indramat and supplied within the VT-HNC Digital Axis Controllers series. It belongs to the HNC100 digital NC control line and is configured for two hydraulic axes, allowing synchronized hydraulic motion control in machinery such as presses and handling stations. By processing incremental or SSI encoder feedback, the unit performs closed-loop position and velocity regulation between higher-level PLC commands and the proportional valves that move each hydraulic cylinder. This arrangement helps the controller correct load-related deviations while keeping both axes aligned during coordinated machine motion.

The controller is part of component series 3 and uses a 32-bit PowerPC processor that supports calculations with a minimum cycle time of 2 ms. Analog feedback channels resolve current inputs to 5 µA and voltage inputs to 5 mV, so small transducer changes can be converted into motion corrections before error increases. Data exchange with distributed controls takes place over Ethernet at 100 Mbit/s, which supports transfer of the cyclic I/O block without creating a communication bottleneck. Each axis also accepts incremental encoder signals up to 250 kHz, allowing the controller to follow fast position changes from common hydraulic feedback devices. Internal control routines keep the paired hydraulic drives synchronized during multi-axis operation.

The open-frame housing has a protection class of IP20, so the unit must be installed inside a control cabinet. Panel space requirements are limited to a height of 120 mm and a width of 88 mm, which helps the controller fit into narrow cabinet layouts alongside other automation hardware. SSI encoder data are accepted with a word length of up to 28-bit, allowing detailed position values from compatible sensors. The device does not use a plug-in bus module and instead relies on its built-in Ethernet connection for host communication. This layout keeps the interface structure straightforward for cabinet-based hydraulic control systems.
