REXROTH VT-HNC100... 3X Series Digital Axis Controller

REXROTH VT-HNC100... 3X Digital Axis Controller: Comprehensive Technical Analysis and Application Guide

Product positioning and functional overview

VT-HNC100... 3X is a programmable digital axis controller launched by Bosch Rexroth, belonging to the 3X series products. This controller is designed specifically for integration into industrial machines or systems, used for open-loop and closed-loop control of up to four electro-hydraulic shafts. Its core functions include position, pressure, force, speed, and differential pressure control, and can be optionally equipped with synchronous operation function. Its typical application areas include machine tools, plastic machinery, specialized machinery, presses, and conveyor systems, and it is the core component for achieving complex motion sequences and precise process control.

As a product designed for harsh industrial environments, VT-HNC100... 3X fully considers anti-interference, mechanical vibration and impact resistance, and climate adaptability in its design. The controller itself does not contain any safety functions for personnel safety, nor is it a safety related component. Its core task is to provide position, pressure, force, and speed control of the hydraulic shaft for machine functions. The complete security monitoring needs to be implemented by higher-level control logic and corresponding I/O components.

Safety regulations and intended use

1. Expected use and limitations

VT-HNC100... 3X is defined as an electrical component that can only be integrated into machines or systems for use. The product must be debugged within the machine/system designed for it and strictly adhere to the operating conditions and performance limits specified in the technical data.

It is strictly prohibited to use it in the following situations:

Explosive environment.

As a safety related control component that complies with DIN EN ISO 13849 standard.

Private use (limited to professional use only).

Any deviation from the intended use is considered as' unintended use ', and Bosch Rexroth assumes no responsibility for it. The related risks are entirely borne by the user.

2. Personnel qualification requirements

Personnel operating, installing, and maintaining VT-HNC100... 3X must possess professional knowledge in electrical installation, control technology, programming, and hydraulic aspects, and understand relevant technical terms. All work must be carried out by qualified technical personnel or under the supervision and guidance of qualified personnel. In addition, operators need to be proficient in PC software WIN-PED ® The use of. Bosch Rexroth strongly recommends that users participate in the product specific training it provides.

3. General safety instructions

Dangerous movement protection: Personnel are not allowed to stay within the range of machine movement. It is necessary to prevent personnel from accidentally entering hazardous areas through measures such as guardrails, protective nets, protective covers, or light curtains.

Electrical safety: All 0-50V connections must use protective extra low voltage (PELV) and be safely isolated from hazardous voltage circuits (such as through isolation transformers, safety optocouplers, or battery power supply).

Product liability: The application cases and recommendations provided by the manufacturer are for reference only. Machine manufacturers or system integrators must independently verify the applicability of the provided components based on their specific safety regulations and standards, and take all necessary measures.

Hardware architecture and technical specifications

1. Product identification and version

The product model is accurately identified through the order code, and the code structure reflects the key configuration:

Axis number: C (compact), 1, 2, 3, 4 axis versions.

Bus type: Supports PROFIBUS DP, CANopen, and PROFINET RT or EtherNet/IP with Ethernet functionality. The PROFIBUS DP version can also be optionally equipped with a TCP/IP service interface.

Firmware and software: Hardware with Ethernet interface (starting from Series 31) requires WIN-PED ®  7 and above versions and firmware 7.05.02 or higher.

2. Core hardware and interfaces

The controller provides rich interfaces to connect sensors, actuators, and higher-level control systems:

Universal interface (all versions):

X1S: Power interface (18-30 V DC).

X3C: RS232 interface, used to connect PC and software WIN-PED ® Parameterize and diagnose.

Bus interface: configured according to the model as X7P (PROFIBUS DP), X7C (CANopen), or X7E1/X7E2 (PROFINET RT/EtherNet/IP).

Axis related interfaces (multi axis versions allocated by slot):

X8M (Encoder): Encoder interface, supporting incremental and SSI absolute encoders, providing+5V,+10Vref, or+24V encoder power supply.

X2A (AIO): Analog input/output interface. Supports 2 analog inputs (Vin), 2 current inputs (Cin), 2 analog outputs (Vout), and 1 current output (Cout), and provides a+24V induction power supply (Vens) for the sensor.

X2D (DIO): Digital input/output interface. Provide up to 11 freely configurable digital I/O points.

Important reminder: The pins marked as "reserved" in the pin allocation diagram are strictly prohibited from being connected.
