Product Description:

The VT-HNC100-1-1X-130-1 digital axis controller is produced by Bosch Rexroth Indramat in the VT-HNC Digital Axis Controllers series. Belonging to the Digital NC control HNC100 platform, it serves as the closed-loop controller for a single hydraulic axis in industrial automation. By processing sensor inputs and issuing analog command signals, the unit lets a proportional valve or drive keep one cylinder or hydraulic motor precisely on its programmed path during machining, pressing, or testing cycles. This arrangement supports stable motion control in equipment that must coordinate hydraulic force, position, and response time within the same control loop.

Hardware on this version is tailored for 1 hydraulic axis, and the component series is identified as 1. Four voltage inputs accept transducer feedback over a ±10 V span, while four current inputs cover the industry-standard 4 to 20 mA loop; both sets use 12-bit conversion. Command signals are delivered through two current outputs and four voltage outputs for valve and actuator control. The controller draws its supply from a 18 to 36 VDC field rail, and real-time calculations are executed by a 16/32-bit MC68376 microcontroller whose timers and communication blocks support deterministic motion. This mix of analog channels and local processing allows the unit to respond quickly to changing feedback conditions during axis movement.

Nonvolatile data storage totals 8 KB of EEPROM for parameters, working memory reaches 256 KB of RAM, and program storage resides in a 1 MB flash EPROM. Total power consumption stays below 8 W, which helps limit cabinet heat even when all outputs are active during continuous use. Diagnostic access is provided through a front-mounted RS232 interface fixed at 9.6 kbaud. For absolute encoders, the SSI port handles data frames up to 28 bits. The memory layout supports parameter retention, temporary operating data, and internal program storage within the main controller housing without requiring additional plug-in cards.
