Common faults and handling 

 

Caution

：

 

 

The drive and motor must be powered off for at least 5 minutes before 

touching the drive and motor to prevent electric shock and burns. 

 

After the drive fault alarm, it must be eliminated according to the alarm code 

before it can be put into use again.
