Parker AC20 15kW Replaces AC690 – Drive Solution for Wire Rewinding Machine

Wire Rewinding and Label Printing Machine

The wire rewinding machine is designed to unwind wire from an input reel, guide it through the production process, print product information labels, and rewind it onto a finished reel.

The drive system consists of two independent Parker drive units: an AC20 controlling the pay-off section and a DC590 controlling the take-up section. Both drives operate in coordination to ensure continuous wire feeding and stable tension throughout the rewinding process.

Parker AC20 15kW Replaces AC690 in the Pay-off Section

In this project, Kỹ Thuật Việt carried out the replacement of the existing Parker AC690 with a Parker AC20 15kW AC Drive to control the pay-off motor.

The drive configuration after the upgrade consists of:

Reel Diameter Calculation and Dancer PID Control

In addition to motor speed control, the system incorporates a reel diameter calculation function and PID control based on dancer position feedback.

The calculated reel diameter is used in the speed calculation and adjustment process to compensate for changes in reel diameter during unwinding and rewinding.

The PID controller uses the dancer position feedback signal to adjust drive speed, helping maintain a stable dancer position and coordinate the operation of the pay-off and take-up sections.

These functions are important for minimizing wire tension fluctuations and ensuring a continuous and stable rewinding and label printing process.

Parker AC Drive and DC Drive Integration Solutions

This project demonstrates the integration of Parker AC Drive and DC Drive technologies within a single machine, while upgrading the discontinued existing AC 690 to AC20 and maintaining the required process control functions.

Kỹ Thuật Việt provides Parker drive products, industrial drive system upgrades, control programming, and automation integration solutions for industrial machinery.
