🚀 Ky Thuat Viet – DC Drive Upgrade Solution for Large-Scale Water Pipe Production Line
In a recent major project, Ky Thuat Viet successfully completed the installation and upgrade of a DC motor control system for the extrusion unit in a production line manufacturing large water pipes up to 1.2 meters in diameter. This project was carried out at a large-scale factory that required high precision and long-lasting drive systems.
The system used a high-power DC motor controller. After a thorough inspection by the KTV technical team, the power stack was found to still be in good condition, while the control board was damaged. To reduce downtime and costs, we proposed replacing only the controller with the Parker DC598 External Stack Controller.

🔧 Technical Solution
- Reused the existing power stack and replaced only the controller with DC598 – saving investment costs.
- DC598 is a specialized external stack controller, designed to work stably with high-power 3-phase thyristor rectifiers.
- Fully compatible with the factory’s existing current and voltage feedback systems.
- Integrated with thermal protection and intelligent control logic.
✅ Achieved Results
- The system operated stably immediately after the upgrade.
- Effectively met torque and speed control requirements in the extrusion unit.
- Allowed the factory to maintain continuous production without replacing the entire system.
- Significantly reduced machine downtime and investment costs.
- DC598 provides superior monitoring and protection features compared to the previous controller, including thermal protection, overcurrent, phase loss, and enhanced safety control modes.
- Flexible programming capabilities allow customized logic for different applications – improving accuracy, safety, and motor lifespan.
