The Rexroth VT-HNC100-1-23/W-08-S-0 is a digital axis controller. Below is an introduction to its parameters,
application scenarios, and operating principle:

1. Parameters

• Axis Count: Supports control of up to 4 axes; this specific model is configured for 1 hydraulic axis.
• Inputs/Outputs: Equipped with 8 digital inputs/outputs.
• Processor: Adopts a 16/32-bit MC68376 processor.
• Operating Voltage: 18 to 36 VDC.
• Storage: Features 1 MB of flash EPROM, 8 KB of EEPROM, and 256 KB of RAM.
• Temperature Range: Operating temperature ranges from 0 to 50 °C.
• Bus Connection: Includes a PROFIBUS DP bus connection.

2. Application Scenarios

• Machine Tool Industry: Used to control the movement of machine tool worktables and the feed of cutting tools, enabling high-precision machining operations to improve processing quality and efficiency.
• Robotics Industry: Precisely controls the joint movement of robots, allowing robots to perform various complex actions and tasks while ensuring motion accuracy and stability.
• Automated Production Lines: Controls the movement of conveying equipment, assembly robots, and testing devices in automated production lines, realizing automation and intelligence of the production process and enhancing production efficiency and consistency of product quality.
• Injection Molding Machines: Enables closed-loop control of melt pressure, reducing energy consumption by 25% during the pressure-holding phase.
• Lithium Battery Manufacturing: Achieves pole piece winding tension control accuracy of ±0.1 N and improves thickness consistency by 18%.
• Aerospace Industry: Applied in multi-axis coordinated movement of composite fiber placement machines, with a curved surface fitting error of <0.03 mm.

3. Operating Principle

• Position Control: Via the position controller (PDT1), the zero error is compensated using the residual voltage principle. Status feedback is provided through pressure, pressure difference, and position, enabling fine positioning. Additionally, gains can be adjusted and valve characteristic curves adapted via NC programs.
• Pressure/Force Control: The pressure/force controller (PIDT1) includes proportional (P), integral (I), and derivative (D) components. The I component can be switched via a window; it analyzes pressure differences and has a customizable scanning time to ensure accurate pressure and force control.
• Speed Control: The speed controller (PI) supports I component switching, suitable for precise speed control and ensuring the dynamic response of the motion system.
• Synchronization Control: The synchronization controller enables coordinated control of up to 4 axes, adopting master-slave or averaging principles to ensure synchronous coordination of multi-axis motion—ideal for controlling complex motion paths.
• Monitoring Function: Features dynamic tracking error monitoring, electronic limit switch detection for stroke range, and cable breakage alarms. It also includes cable breakage detection for incremental encoders and SSI encoders, ensuring safe and stable operation of the system.
