Fault type symbol
Meaning
A
(Alarm)
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.
F
(Fault)
An 'F fault' makes the drive stop. Actions need to be
taken to restart the drive.
AR
(Fault Autoreset)
If an 'AR fault' occurs the drive will 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.
FT
(Fault Trip)
If the drive is unable to restart the motor after an AR
fault an FT fault occurs. The 'FT fault' has basically the
same effect as the F fault: the drive is stopped.
