#acs800

In the world of industrial drives, ABB ACS800 drives are the backbone of heavy-duty motors in cement plants — controlling crushers, conveyors, and fans. These drives work under extreme dust, heat, and continuous operation. Without proper care, unexpected trips or downtime can halt production and cost a lot.

At Najran Cement, our team carried out a comprehensive preventive maintenance program for ABB ACS800 drives to ensure reliability, reduce downtime, and extend their lifetime.

What We Did

Internal Cleaning: Removing cement dust affecting airflow and cooling

Cooling System Check: Fans, filters, and heat sinks inspected

Power Connections: Terminals tightened, DC bus checked

Module Inspection: IGBT modules and capacitors verified

Fault Review: Alarm history analyzed to prevent future trips

Functional Testing: Drives tested for smooth operation

Results

Reduced drive temperature and nuisance trips

Improved reliability for continuous operation

Extended drive lifetime

Lowered risk of unplanned downtime

Why Preventive Maintenance Matters

In cement plants, dust + heat + heavy loads = potential failures. Preventive maintenance is not just a cost — it’s a production protection strategy. Small interventions today prevent major shutdowns tomorrow.

To improve pump control and eliminate downtime, our team delivered the complete supply, installation, and commissioning of the ABB ACS800-04M-0320-5 AC Drive for a major water treatment plant in Makkah.

Why this project was critical

Water plants rely on continuous motor operation. Without proper VFD commissioning, issues like overcurrent, unstable speed, and high energy consumption can appear quickly.

What we did

Installed and wired the ACS800 drive inside the control panel

Configured parameters for pump application

Integrated with PLC and protection system

Performed full testing & commissioning under load

Results

Stable and reliable pump performance

Zero faults after commissioning

Better energy efficiency

Client satisfaction and long-term reliability

Correct VFD commissioning is the key to performance and reliability in water treatment plants.

At Attieh Steel, the team from Riyadh Al Etqan successfully troubleshooted an ABB ACS800 260KVA Low Voltage Drive.

What We Did:

✅ Replaced faulty IGBTs ✅ Recovered AINT & RDCU modules ✅ Restored the drive into normal operation

Why It Matters:

Unplanned downtime in heavy industries like steel production can cause major production and financial losses. Our expertise in LV drive troubleshooting ensures:

Minimal downtime

Extended equipment life

Improved reliability

This case study highlights how Riyadh Al Etqan supports industrial plants with professional troubleshooting and maintenance.

We successfully supplied, commissioned, and started up an ABB ACS800 160kW low voltage VFD on a heavy-duty crane operating in Ras Tanura.

This drive delivers: – Safe and stable hoisting under load – High-efficiency performance – Seamless integration with existing crane control systems
