* indicates the errors selected for retry.
• Use Pr. 67 to set the number of retries at alarm occurrence.
Pr. 67 Setting
0
1 to 10
101 to 110
* If the number of retries to be made is exceeded, "
• Use Pr. 68 to set the waiting time from when an inverter alarm occurs until a retry is made in the range 0 to 10s.
• Reading the Pr. 69 value provides the cumulative number of successful restarts made by retries. Writing "0"
erases the cumulative number of times.
CAUTION
• 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) being activated
during a period four times longer than the time set in Pr. 68.
• If the protective function (major fault) is activated consecutively within a period four times longer than
the above waiting time, the control panel may show data different from the latest data or the parameter
unit (FR-PU04V) 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) activated the first time.
• When an inverter alarm is reset by the retry function at the retry time, the accumulated data of the
electronic thermal relay function, 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 predetermined time has elapsed) after occurrence of an alarm.
When you have selected the retry function, apply the CAUTION seals provided for the Instruction
Manual (basic) in easily visible places.
