 To determine the number of times to retry when the following faults occur:
7: Over-voltage during acceleration (ovA)
8: Over-voltage during deceleration (ovd)
9: Over-voltage during constant speed (ovn)
10: Over-voltage at stop (ovS)
11: Low voltage during acceleration (LvA)
12: Low voltage during deceleration (Lvd)
13: Low voltage during constant speed (Lvn)
14: Low voltage at stop (LvS)
15: Phase loss (PHL)
 After every retry attempt, the number of times to retry is automatically reduced by one as
displayed on the keypad.
 The principles for the number of times to reset:
1. Reset the fault manually.
2. After running normally for 10 minutes, the motor drive returns to previous settings.
3. The motor drive is powered on and powered off again.
 When the fault is attempted to be automatically cleared by system and if multi-function output
(MO) is set to 46, then, at this time, MO will be activated. This is used to inform the host
controller that the drive is currently clearing the fault automatically.
