Chapter 5 Fault Protection and Disply and Trobleshotting 

a: Description: 

The drive has well protection functions to protect drive and motor when faults 
occur. When the fault occurs, the drive trips by the protection functions and 
display fault message on keypad. After the fault is troubleshooted, reset the 

drive by pressing 

OFF

RESET

  of keypad or command the drive to reset through 

multi-function input terminals by an external reset signal
