F.3 Fiber Dust Problem
Serious fiber dust problems generally occur in the textile industry. Please be aware of the
possible damages that fiber may cause to your drives:
1. Fiber that accumulates or adheres to the fans will lead to poor ventilation and cause
overheating problems.
2. Plant environments in the textile industry have higher degrees of humidity that may
cause the drive to burn out, become damaged or explode due to wet fiber dust
adhering to the devices.
Solution:
Install the AC motor drive in a standard cabinet to keep it away from fiber dust. Clean and
remove fiber dust regularly to prevent damage to the drive.
