Product Description:
The VT-HNC100-SEK-20a/W-24-0-C/V240 is a digital axis controller manufactured by Bosch Rexroth Indramat for the VT-HNC Digital Axis Controllers series. Installed directly on a machine wall, it coordinates hydraulic or electromechanical axes by executing interpolated motion sequences and exchanging status data with an upstream PLC. Within industrial automation, the device serves as the local motion processor, closing position and velocity loops so multiple cylinders or servo drives follow programmed trajectories. It also belongs to the Digital NC control HNC100 product range used in presses, die-casting machines, and handling equipment.
Field communication is handled through the CANopen bus, allowing deterministic messaging between the controller, drives, and decentralized I/O. The front panel accepts 24 digital inputs for limit switches or sensor flags and provides 24 digital outputs for valve or relay actuation. An MC68376 32-bit microcontroller executes motion routines, supported by 256 KB of static RAM that holds real-time data structures. Four current input channels capture feedback from pressure transducers, while two current outputs modulate proportional valves. The mixed-signal section adds four voltage inputs and four voltage outputs for axis commands or diagnostic tasks. This combination allows the controller to process discrete signals and analog feedback while issuing commands to connected equipment.
Persistent parameters reside in an 8 KB EEPROM, and control software is stored in a 1 MB flash EPROM that can be updated in the field. The steel housing measures 155 mm high, 106.5 mm wide, and 204 mm deep, allowing it to fit on a machine wall or inside a suitable control enclosure. With a mass of 1.2 kg, the assembly mounts on standard backplates without additional bracing, and its wall-mounting brackets allow airflow around the housing for convection cooling.
