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 14-20 Reset Mode
(Warning: Automatic wake-up is possible.)
If a warning or alarm is marked against a code in Table 6.4,
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.

User Guide
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 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 are active when parameter 1-10 Motor
Construction is set to [1] PM non-salient SPM.
