6 Troubleshooting
6.1 Status Messages
A warning or an alarm is signaled 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 rectied.
3 ways to reset:
•
Press [Reset].
•
Via a digital input with the reset function.
•
Via serial communication/optional eldbus.
NOTICE
After a manual reset pressing [Reset], press [Auto On] to
restart the motor.
If an alarm cannot be reset, the reason may be that its
cause has not been rectied, or the alarm is trip locked
(see also Table 6.1).
Alarms that are trip locked oer extra protection, meaning
that the mains supply must be switched o 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 rectied.
Alarms that are not trip locked can also be reset using the
automatic reset function in parameter 14-20 Reset Mode
(Warning: Automatic wake up is possible.)
If a warning or alarm is marked against a code in Table 6.1,
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 1-90 Motor
Thermal Protection. After an alarm or trip, the motor carries
on coasting, and the alarm and warning ash. Once the
problem has been rectied, only the alarm continues
ashing until the frequency converter is reset.
NOTICE
No missing motor phase detection (numbers 30-32) and
no stall detection are active when parameter 1-10 Motor
Construction is set to [1] PM non-salient SPM.
