Product Description:

The VT-HNC100-1-1X-132-13 is a digital axis controller produced by Bosch Rexroth Indramat for the VT-HNC Digital Axis Controllers series. It also belongs to the Digital NC control HNC100 product series. It coordinates one hydraulic axis by generating precise analog commands and evaluating feedback signals so that cylinders or valves can be positioned with repeatable accuracy in automated presses, plastic-processing machines, test rigs, and similar hydraulic equipment. The controller is intended for machines that depend on monitored feedback rather than open-loop hydraulic actuation.

Control performance begins with the MC68376 16/32-bit processor that executes closed-loop routines stored in 1 MB of flash, backed up by 256 KB of RAM and an 8 KB EEPROM for parameter retention. A maximum encoder frequency of 250 kHz lets the SSI interface handle 28-bit position words without missed counts. Analog measurement is digitized at 5 mV resolution, and communication with setup software is handled through an RS-232 port set to 9.6 kbaud. The unit draws only 8 W, easing cabinet thermal design, and it supplies sensors with 200 mA from its dedicated transducer output. Command outputs can drive ±10 mA, while two transistor stages source 50 mA for binary actuators. Current-loop inputs use a tightly controlled impedance, and voltage inputs rely on a 500 Ω burden resistor. The memory arrangement keeps operating routines and retained parameters separated inside the controller.

Signal quality is reinforced by an output resolution of 1.25 mV, permitting fine control across the calibrated span of ±10 V ±25 mV. On the feedback side, the strict 100 Ω ±0.2% input impedance stabilizes current-loop measurements. These signal characteristics support smooth command behavior and accurate response in closed-loop hydraulic control. Fine electrical granularity helps the unit regulate valve or cylinder motion without coarse command steps during positioning.
