Product Description:

The VT-HNC100-4-3X-P-I-00-000 is a digital axis controller manufactured by Bosch Rexroth Indramat for hydraulic motion control applications. It belongs to the VT-HNC Digital Axis Controllers series and to the HNC100 product line, where it processes setpoint commands and sensor feedback for accurate closed-loop positioning. The controller is intended for presses, die-casting machines, and assembly stations in which multiple cylinders or valve-controlled axes must follow programmed motion profiles with consistent response. By evaluating command values together with returned position signals, it helps hydraulic axes maintain repeatable motion during pressing, clamping, or transfer cycles.

At the hardware level, the controller supports 4 hydraulic axes, so one enclosure can regulate four independent servo-hydraulic drives without external expansion cards. Signal exchange uses configurable digital I/O, and each slot provides 11 channels that can be assigned as inputs or outputs for valve enable signals, limit switches, or alarm handling. This arrangement allows the same controller platform to adapt to different machine sequences without changing the basic control concept. Installation uses top-hat rail mounting, so the housing clips directly onto a DIN rail with a width of 35 mm. During operation, the electronics are protected by an IP20 enclosure, which is intended for installation inside cabinets with controlled ambient conditions.

The device is identified as component series 3. It provides 4 digital I/O slots, and internal multiplexing allows up to 20 switchable outputs for pilot valves or status relays. Host communication uses a standard RS232 serial interface, and the unit does not include a fieldbus connection, a TCP/IP interface, or axis-to-axis synchronization. That layout suits applications in which a higher-level controller handles overall machine coordination while the axis controller focuses on local hydraulic regulation. An inductive position sensor is not integrated, which allows external LVDTs or SSI encoders to be selected to match the cylinder layout, stroke arrangement, and required feedback method.
