REXROTH Digital axis control HNC100

REXROTH Digital axis control HNC100

Product Overview

Product positioning and types

VT-HNC100 is a programmable NC controller developed by Bosch Rexroth AG, specifically designed for closed-loop control shafts. It meets the specific requirements of hydraulic drive closed-loop control and can also be used for electric drive control. The products are divided into two main types:

VT-HNC100-1: Single axis version, supports 8 or 24 digital inputs/outputs

VT-HNC100-2: Dual axis version, supports 16 digital inputs/outputs

Both belong to the 2X component series (20-29 series, with unchanged installation and connection dimensions), comply with the EC directive (CE mark), and exhibit excellent anti-interference, mechanical anti vibration and shock resistance, and weather resistance, making them suitable for harsh industrial environments.
