Common Questions

What is the main advantage of this drive model?

It provides stable motor control with high overload capacity, perfect for applications requiring sudden power increases.

How should I plan the electrical connections?

Use proper cable sizing for 250A capacity and ensure three-phase power supply meets voltage specifications.

What maintenance does the cooling system need?

Keep fan vents clean and check airflow regularly. Dust buildup can reduce cooling efficiency over time.

Can I parallel multiple drives together?

No, this unit operates independently. Each motor needs its own controller for optimal performance.

What happens during voltage fluctuations?

The drive tolerates ±10% voltage variation. Beyond this range, it may shut down to protect connected equipment.
