Product Description:

The VT-HNC100-1-2X-M-24-0-C-INK2 is a digital axis controller manufactured by Bosch Rexroth Indramat within the VT-HNC Digital Axis Controllers series. Classified in the HNC100 product line, it is intended to control a single hydraulic axis by processing closed-loop motion commands and valve actuation in presses, forming machines, and similar equipment. Because it is a digital NC controller, it can compare commanded motion with axis feedback and correct deviations during operation. The module combines processing functions, memory, and sensor interfaces on one card, which reduces the amount of additional hardware needed in the control cabinet.

The controller occupies 204 mm of depth, 106.5 mm of front width, and 155 mm of height inside the rack. It is designed for rack installation and is supplied without a bus connection, so separate fieldbus wiring is not required for this version. A set of 24 digital inputs and outputs provides connections for limit switches, start contacts, and status lamps. Parameter sets are stored in 8 KB of EEPROM, which allows saved settings to remain available after power is removed. Program code resides in 1 MB of Flash EPROM. Real-time interpolation and axis calculations are handled by a 16/32-bit MC68376 microcontroller, which supports deterministic execution of motion loops.

The controller uses 256 KB of RAM for trajectory buffers and diagnostic data during operation. Power consumption is limited to 8 W, which helps reduce heat inside the cabinet, and the unit has a mass of 1.2 kg for easier handling during installation. It belongs to component series 2 within the HNC100 platform. Position feedback is taken from two IW9 inductive sensors, which are supplied by a dedicated 2 V channel on the controller. A counter interface serves as the second special function and allows high-resolution stroke or rotation tracking when auxiliary encoders are connected.
