This type of fault is a sign of an unusual operating
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.
An 'F fault' is a kind of fault that makes the drive stop.
Actions need to be taken in order to restart the drive.
If an 'AR fault' occurs the drive will also stop
immediately. 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.
If the drive is unable to restart the motor after an AR
fault an FT fault occurs. The effect of the 'FT fault' is
basically the same as that of the F fault: the drive is
stopped.
