These controls are intended to be integrated into a system or a machine or electrically assembled with other components to form a system or a machine. They can be commissioned only if the integration or assembly is done. The digital axis controls are used in machine tools, plastics processing machines, translator lines, presses and rail-bound vehicles.

VT-HNC digital axis controls can be programmed by users with a PC or an NC language with conditional jumps and subprogram techniques. The Rexroth controls can also be parameterized using a local CAN bus.  They help in controlling the position, velocity and pressure as well as assist in the synchronous operation of up to four electro-hydraulic axes. These digital axis controls are programmed, set up and diagnosed using a WIN-PED 5 or higher version PC program. The controls should be used only in safety-relevant applications to avoid uncontrolled operating conditions that can trigger unfavorable consequences. We can fix your broken digital axis controllers fast with a one-year warranty.

• VT-HNC digital axis controls must not be used in explosive areas, although some of them can be used in harsh industrial environments. They should be deployed only for professional use and not personal use.
• The hydraulic axes of the Rexroth digital axis controls produce a voltage or current control variable output and can be measured using an incremental or absolute measuring system.
• The controls are intended to be used only with accessories and spare parts that are authorized by the manufacturer.
• The complete range of VT-HNC digital axis controls must comply with the ambient conditions and technical data specified in their documentation.
• The digital axis controls can be connected to superior controls using a PROFIBUS DP, an Ethernet-capable PROFINET RT or a CANopen bus system.

The PC program of the VT-HNC digital axis controls must be downloaded from the manufacturer’s website. The controls must always be kept protected from dust and humidity. They must be operated at a temperature between 0°C and 50°C and stored between -20°C and 70°C. The digital axis controls are likely to get damaged if their plugs are connected or disconnected under voltage.

The digital controls are designed for top-hat rail assembly in the control cabinet. They must not be installed next to power electronics sources such as frequency converters. The voltage supply connection of the VT-HNC digital axis controls should be as short as possible.
