Time delay
The first clear is attempted 1 second after the detected fault occurs. Each subsequent clear attempt adds 1
second to the time interval, as illustrated in the table below.
Clear detected fault attempts
Fault relay action
An output relay set to functions 10 and 11 (see table on page 98
) will not indicate a detected fault until all clear
attempts have been exhausted.
Output relay functions 28 and 29 can be used to indicate that an auto-resetable detected fault has occurred.
Output relay functions 36 and 37 can be used to signal any kind of drive detected fault, even during auto clear
attempts.
Drive fault memory
If parameter [Drive fault memory]
(F602) is set to 1 and power to the drive is cycled while an auto-resetable
detected fault is active, the auto clear action will be cancelled (see page 127).
