5.1.1 Warnings/Alarm Messages
A warning or an alarm is signalled by the relevant indicator
light on the front of the frequency converter and indicated
by a code on the display.
A warning remains active until its cause is no longer
present. Under certain circumstances, operation of the
motor may still be continued. Warning messages may be
critical, but are not necessarily so.
In the event of an alarm, the frequency converter trips.
Reset the alarm to resume operation once the cause has
been rectified.
3 ways to reset:
•
Press [Reset].
•
Via a digital input with the reset function.
•
Via serial communication/optional network.
NOTICE
After a manual reset pressing [Reset], press [Auto] to
restart the motor.

AF-650 GP™ Programming Guide
If an alarm cannot be reset, the reason may be that its
cause has not been rectified, or the alarm is trip locked
(see also Table 5.1).
Alarms that are trip locked offer extra protection, meaning
that the mains supply must be switched off before the
alarm can be reset. After being switched back on, the
frequency converter is no longer blocked and can be reset
once the cause has been rectified.
Alarms that are not trip locked can also be reset using the
automatic reset function in parameter H-04 Auto-Reset
(Times) (Warning: Automatic wake-up is possible.)
If a warning or alarm is marked against a code in Table 5.1,
this means that either a warning occurs before an alarm, or
it is possible to specify whether a warning or an alarm
should be shown for a given fault.
This is possible, for instance, in parameter F-10 Electronic
Overload. After an alarm or trip, the motor carries on
coasting, and the alarm and warning flash. Once the
problem has been rectified, only the alarm continues
flashing until the frequency converter is reset.
NOTICE
No missing motor phase detection and no stall detection
are active when parameter P-20 Motor Construction is set
to [1] PM non-salient SPM.
