Use Pr. 67 to set the number of retries at alarm occurrence.
Pr. 67 Setting
0
1 to 10
101 to 110
y Use Pr. 68 to set the waiting time from when an inverter alarm occurs until a restart
in the range 0.1 to 360 seconds.
y Reading the Pr. 69 value provides the cumulative number of successful restart
times made by retry. The setting of "0" erases the cumulative number of times.
Note: 1. The cumulative number in Pr. 69 is incremented by "1" when retry operation
is regarded as successful, i.e. when normal operation is continued without
the protective function (major fault) activated during a period five times
longer than the time set in Pr. 68.
2. If the protective function (major fault) is activated consecutively within a
period five times longer than the above waiting time, the control panel may
show data different from the most recent data or the parameter unit
(FR-PU04) may show data different from the first retry data. The data stored
as the error reset for retry is only that of the protective function (major fault)
which was activated the first time.
3. When an inverter alarm is reset by the retry function at the retry time, the
stored data of the electronic over current protection, etc. are not cleared.
(Different from the power-on reset.)
When you have selected the retry function, stay away from the motor and
machine unless required. They will start suddenly (after the reset time
has elapsed) after occurrence of an alarm.
When you have selected the retry function, apply the supplied CAUTION
seals in easily visible places.
