Intuitive Touch Software for Winding Machines – Powerful & Versatile

The user interface was specially developed for intuitive and efficient touch operation on winding machines.

In addition to essential functions such as Open, Save, Copy, Delete, Edit, and Print winding programs, the software offers numerous advanced features:

  • Integrated language switch for international use
  • Extensive configuration options
  • Service-relevant diagnostic tools
  • Tools for system optimization and machine customization

Thanks to its clearly structured interface, the software supports both machine operators in daily production and technical staff during machine configuration and customization.

Home screen – central user interface Display of main winding parameters and activated setup functions Display of main winding parameters and special functions
Manual functions Programming page for entering all relevant winding parameters Programming page with example – copying the right reversal point
Programming page for entering all relevant winding parameters Programming functions & control, winding types extension Display and acknowledgment of already corrected errors
Overview of active error messages INPUTS: Configuration of programmable inputs and outputs with various options Language switching – also supports Cyrillic and Chinese

This interface allows users to open winding programs from various storage sources: internal iSATA drive, USB stick, network drive (FTP server), or USB floppy disk drive. As the number of stored programs increases over time, a built-in search function helps streamline selection. By entering the first three characters, the program list is automatically filtered to show relevant matches. Programs can also be saved to all of the above storage media, internal iSATA drive, USB stick, network (FTP), and floppy disk drive.

🔧 Dynamic Working Lines – RWC301

The adjacent diagram illustrates the relationship between the winding radius and the resulting wire tension force under various operating conditions of the RWC 301 winding machine.

As the winding radius increases – meaning the spool diameter becomes larger – the force at the winding axis decreases. The physical principle is simple:

Power = Torque × Speed

Since the machine's power remains constant, the torque decreases as speed increases – and with it, the achievable wire tension force.

📊 Timing Belt Comparison Table – RWC301-S / RWC301-V / RWC301-V2

Belt Set Speed (RPM) RWC301-S RWC301-V RWC301-V2 Description
0 750 50.4 Nm 64.0 Nm 80.0 Nm Maximum torque – for large coils and high pulling forces
1 1500 25.2 Nm 32.0 Nm 40.0 Nm Balanced setup – standard for wide range of applications
2 3000 12.6 Nm 16.0 Nm 20.0 Nm Direct drive – nominal speed of the AC servo motor
3 6000 6.3 Nm – – High speed – ideal for smaller wire diameters

📈 Diagram Interpretation

  • The colored lines represent the wire tension [N] depending on the winding radius [mm] for models RWC 301-S, RWC 301-V, and RWC 301-V2.
  • The left Y-axis is logarithmically scaled to show both low and high tension forces clearly.
  • The right Y-axis shows typical wire diameters [mm] as a reference for wire selection.
  • The larger the winding radius, the lower the resulting force – which influences the drive configuration choice.

🧩 Practical Application

This graphic makes it easier to choose the right drive configuration:

  • Adjustment to wire diameter (e.g. 0.25 mm vs. 3.0 mm)
  • Consideration of the required tension range
  • Depending on the desired winding speed
  • Optimized for the respective spool diameter

The RWC 301 can thus be optimally adapted to various applications in sensor and transformer manufacturing.

🔎 Note: For machines with two spindles, the effective torque per spindle is halved. The actual wire tension also depends on the wire brake and may vary accordingly.
