8.6 Troubleshooting

A warning or alarm is signalled 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 terminated.
Under certain circumstances, operation of the motor may
still continue. Warning messages are sometimes critical,
but not always.
In the event of an alarm, the frequency converter trips.
Reset alarms to restart operation once their cause has
been rectified.

There are 4 ways to restart after an event:
1. Pressing [RESET] on the LCP.
2. Via a digital input with the "Reset" function.
3. Via serial communication/optional fieldbus.
4. By resetting automatically using the Auto Reset
function, which is a default setting for VLT
Drive. See 14-20 Reset Mode in the VLT
Basic Drive FC 102 Programming Guide
NOTICE
After pressing [RESET] , press the [Auto On] or [Hand On]
button to restart the motor.
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 8.25).
