15-3 Fiber Dust Problems
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 leads to poor ventilation and causes 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.
