In legacy electrical setups, engineers typically relied on the A/D and D/A modules of a PLC, utilizing a PCB integrated with tension control techniques. The system determined the pay-off speed by reading the potential from a potentiometer paired with a tension swing bar.

However, maintaining constant tension through this traditional method presented distinct disadvantages:

• Signal Distortion: The signal lines running from the tension swing bar’s potentiometer and the analog lines from the D/A module (which controlled the VFD speed) were often excessively long, making them highly susceptible to electrical noise and signal distortion.

• Complex Tuning: Take-up wheels with varying axis diameters required different internal PID parameters within the PLC. If these PID settings were even slightly inaccurate, the pay-off line easily became unstable, making it exceptionally difficult to maintain a constant tension—ultimately compromising the final product quality.

The Hibba Traders Solution

The application of the Hibba Traders VFD in the wire and cable industry has completely resolved the complex electrical control challenges associated with power pay-off wire racks and take-up wheels.

By upgrading to the Hibba Traders drive system, you gain significant operational advantages:

• Simplified Wiring: The overall line connection is remarkably simple and clean.

• Built-in Intelligence: The VFD features its own integrated PID and closed-loop control functions, completely eliminating the need for external A/D/D/A modules or complex PLC programming.

• Ease of Maintenance: Because of its user-friendly architecture, any standard electrical maintenance worker can easily operate and manage the system.

For factories looking to modernize, the Hibba Traders VFD stands out as the premier choice for retrofitting and reforming legacy pay-off wire racks across the wire and cable industry.
