Fault type symbol Meaning
A This type of fault is a sign of an unusual operating
(Alarm) condition. It does not cause the drive to stop, nor does it
require any special actions. The 'A fault' remains in the
display for about 30 seconds.
F An 'F fault' is a kind of fault that makes the drive stop.
(Fault) Actions need to be taken in order to restart the drive.
AR If an 'AR fault' occurs the drive will also stop immediately.
(Fault Autoreset) The fault is reset automatically and the drive tries to
restart the motor. Finally, if the restart is not successful, a
fault trip (FT, see below) occurs.
FT If the drive is unable to restart the motor after an AR fault
(Fault Trip) an FT fault occurs. The effect of the 'FT fault' is basically
the same as that of the F fault: the drive is stopped.
