PARAMETERS
Use Pr. 67 to set the number of retries at alarm occurrence.
•
Use Pr. 68 to set the waiting time from when an inverter alarm occurs until a restart in
the range 0.1 to 360s.
•
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.
Pr. 67 Setting Number of Retries Alarm Signal Output
0 Retry is not made.

1 to 10 1 to 10 times Not output.
101 to 110 1 to 10 times Output.
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 operation panel
may show data different from the most recent data or the parameter unit
(FR-PU04-MGI) 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 thermal relay function, etc. are not cleared.
(Different from the power-on reset.)
CAUTION
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
stickers easily visible places.
Pr. 66 Refer to Pr. 22.
Pr. 70 Refer to Pr. 30.
