REXRTOH HNC100-3X Electro hydraulic Motion Control

Control axis number, analog input (U/I), analog output (U), digital I/O (configurable), SSI/incremental encoder

1 axis 4 (2U+2I) 2 11 points (up to 20 output points) 1

2 axes, 8 (4U+4I), 4 22 points (up to 20 output points), 1 per axis

3-axis 12 (6U+6I) 5 33 points (up to 20 output points) 1 per axis

4-axis 16 (8U+8I) 6 44 points (up to 20 output points) 1 per axis

This configuration ensures that each axis has sufficient sensor signal interfaces and valve drive outputs, without the need for additional expansion modules, simplifying the system structure.

3. Rich communication interfaces:

Standard configuration: RS232, used for basic services and parameter settings.

Optional: PROFIBUS DP/V0, PROFINET RT, EtherNet/IP. The multi axis version also comes standard with a TCP/IP service interface for advanced diagnostics and network communication.

Software and Function: Intelligent Core for Deep Optimization of Hydraulic Control

The power of HNC100-3X is largely due to its software feature set specifically designed for hydraulic optimization.

1. High performance control core:

The controller supports variable scanning cycles, with a single axis scanning time of up to 0.5ms, providing a solid performance foundation for high dynamic response hydraulic servo systems. Its control algorithm has been specially tuned to effectively handle the inherent nonlinearity, hysteresis, and time-varying parameters of hydraulic systems.

2. Rich hydraulic dedicated control functions:

Multi mode control: integrates extended position controller, pressure/force controller, and speed controller, and can seamlessly switch during motion. For example, a typical "position pressure" alternating control can be used in press fit processes to smoothly switch to pressure control after reaching the position.

Hydraulic valve adjustment function: The built-in tool simplifies the zero position and gain calibration of proportional valves or servo valves.

Advanced process functions: including slope function, curve function, virtual cam, multi axis synchronization (2-4 axis synchronization), complex mathematical operations, and contour sequence generation.

3. Comprehensive security and monitoring functions:

To ensure the safety and reliability of the system, the controller integrates multiple monitoring systems: control error monitoring, analog signal cable breakage monitoring, encoder breakage monitoring, travel range limit monitoring, and synchronization error monitoring. These features can prevent device damage and significantly reduce troubleshooting time.

4. Engineering software WIN-PED 7:

This is the core tool for configuring HNC100-3X. It provides an integrated project environment that includes:

Project View: Centralize management of all hardware configurations, parameters, and programs.

Editor: Supports NC language programming that complies with DIN 66025 standards (similar to machine tool G-code), making motion sequence programming particularly familiar to engineers with machine tool backgrounds. For example, switching from position to pressure control only requires a few lines of instructions.

Bus Manager: Intuitively configure network communication.

WinView diagnostic tool: real-time data tracking and recording, is a powerful tool for performance optimization and fault analysis.

Typical Applications and Value Manifestations

The flexibility of HNC100-3X makes it stand out in many industries that require hydraulic power:

Plastic machinery: injection molding machines, blow molding machines, rubber injection presses, achieving precise position and pressure control.

Metal Forming: Compressors, bending machines, stamping machines, hydraulic forming systems, complete high-speed and high-precision synchronous actions.

Rolling and steel: rolling mill, drawing system, swing crystallizer control.

Special equipment: packaging machines, lifting equipment, assembly machines, test benches, etc.

For machine manufacturers, their value lies in:

Shortening time to market: Mature function libraries and easy-to-use tools simplify engineering debugging.

Improving machine performance: Optimized control algorithms enhance motion accuracy, production pace, and energy efficiency.

Reduce total cost of ownership: Reliable hardware and powerful diagnostic capabilities reduce downtime and maintenance costs.

Protecting intellectual property: Protecting applications with passwords to prevent the leakage of core process knowledge.
