6-5 Industrial Dust Problem 
Serious industrial dust pollution frequently occurs in stone processing plants, flour mills, cement 
plants, and so on. Please be aware of the possible damage that industrial dust may cause to your 
drives: 
1.  Dust accumulating on electronic components may cause overheating problem and shorten the 
service life of the drive. 
2.  Conductive dust may damage the circuit board and may even cause the drive to explode.   
Solution: 
Install the hybrid servo drive in a standard cabinet and cover the drive with a dust cover. Clean the 
cabinet and ventilation hole regularly for good ventilation.
