10.3.1 Warnings/Alarm Messages

A warning or an alarm is signaled by the relevant LED 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.
Three 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™ Design and Installation Guide
If an alarm cannot be reset, the reason may be that its
Alarm LED
cause has not been rectified, or the alarm is trip-locked
Off
(see also Table 10.2).
On (Flashing)
On (Flashing)
Alarms that are trip-locked offer additional 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 as described above 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 10.2, this means that either a warning occurs before
an alarm, or else that 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 (numbers 30–32) and
no stall detection is active when parameter P-20 Motor
Construction is set to [1] PM non-salient SPM.
