C090 - AutoReset
** times
R
0 ... 10 times
D
0 times
F
This parameter programs the max. number of autoreset retries of an alarm
(autoreset) which may be performed (when 2s have passed since the removal of
the alarm) in a time interval equal to the time set for parameter
C091(AutoResTime).
Set C090 = 0 to disable the function.
7.3.24 C091: RESETTIME OF AUTORESETNUMBER
C091 AutoResTime
P
C091 - AutoResTime
*** sec
R
1 ... 999 s
D
300 s
F
If the autoreset function has been preset (C090 > 0) after that the first alarm has
self-reset, time keeping starts for this parameter, C091. Within this time interval,
a number of autoreset attempts equal to the maximum number set in. par. C090
(AutoReset) can be obtained.
If a time longer than the set time passes between two autoreset attempts, the
autoreset counter resets. Otherwise, if an additional alarm occurs that increases
the counter above C090, the converter may be reset only manually.

F
This parameter determines whether no memorization should be performed in
the EEPROM after an alarm trip, so that the alarm will not be displayed at the
following drive power on (if, of course, the alarm cause has been removed).
0:No. The alarm trip is stored and displayed when the drive is powered on
again.
1:Yes. The alarm trip is not stored, so it is not displayed when the drive is
powered on again.
7.3.26 C093: AUTORESET AFTER MAINS FAILURE
C093 MainsReset

R

F
This parameter determines whether the drive, in case of a mains break
(regardless of its duration) concerning the power section, is able to perform an
unlimited number of alarm autoresets, in such a way that by restoring the power
supply no alarm is kept stored. As a rule, the generating alarm is A007
(MainsFailure), though it may sometimes happen that alarms A006 (Unstable
Frequency), A012 (Frequency out of Range), A013 (Missing Synchronization) or
A017 (Mains Undervoltage) have tripped.
0:No. When the power supply is restored after a mains break on the power
section, one of the above mentioned alarms is kept stored.
1:Yes. When the power supply is restored after a mains break on the power
section, no alarm trip is kept stored.
