Project Background
Our client is an established food packaging equipment OEM headquartered in Colombia, South America. The company manufactures complete packaging machinery lines — including vertical form-fill-seal (VFFS) machines, conveyor systems and food filling equipment — and supplies local food processing plants with turnkey production solutions. As demands on throughput and reliability grew, the OEM faced a recurring challenge: their previous variable frequency drive (VFD) supplier delivered long lead times, and the drives frequently tripped fault codes under Colombia's unstable grid conditions.
The Challenge
Food packaging lines operate in demanding environments where motor synchronization, timing and torque control directly determine output quality. The OEM's legacy drives presented several critical problems:
- Heavy start/stop shock: abrupt acceleration caused film tearing and misaligned sealing, raising material waste.
- Grid instability faults: voltage fluctuations repeatedly triggered over-current trips, halting production.
- Long procurement cycles: overseas suppliers of European and American brands could not meet the OEM's fast delivery commitments.
- Multi-motor synchronization: each line combined conveyors, unwinding and sealing stations that required precise, coordinated speed control.
The Solution: LD350 Series Vector Inverter
After an on-site electrical review, we recommended the LD350 series vector frequency inverter, a robust drive engineered for high-torque, stable operation. Our support covered every stage of the project:
- Pre-sales drive selection: matching inverter models to each motor load and torque requirement.
- Parameter commissioning: guided setup of PID, torque and V/F parameters for smooth multi-motor synchronization.
- Remote technical support: live troubleshooting and tuning assistance throughout commissioning.
- Fast spare-parts delivery: rapid shipment of units and spares to keep the OEM's inventory lean.
Results & Performance Data
The retrofit delivered measurable, immediate improvements across the packaging line:
| Metric | Result |
|---|
| Film pulling loss / waste | Reduced by approx. 12% |
| Downtime / fault frequency | Reduced by 70% |
| Machine commissioning time | Shortened by 30% |
| Spare parts inventory cost | Lowered; lead time far better than EU/US rivals |
| Grid fluctuation resilience | Continuous, stable operation |
Start and stop transitions are now smooth, eliminating the sealing misalignment and film tearing caused by the old drives. The LD350's strong tolerance to grid voltage swings keeps the line running without the over-current trips that previously stopped production. Faster commissioning also allows the OEM to ship finished machines more quickly, improving its delivery competitiveness.
Compliance & Applications
The LD350 units satisfy local voltage specifications and carry CE certification, meeting the requirements for packaging equipment exported across South America. The solution suits vertical form-fill-seal machines, conveyor lines and food filling machinery — any application demanding reliable multi-motor speed control.
Why It Matters
For food packaging OEMs, drive reliability is not a minor detail — it is a direct driver of product quality, uptime and profit. By replacing a slow, fault-prone supply chain with the LD350 vector inverter and responsive support, our Colombian customer secured a stable, cost-effective and fast-delivery motion control platform for its entire packaging range.
