Mitsubishi Electronics FR-S500 instruction manual

Operation selection function parameters

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) 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 operation 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.

•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 in easily visible places the CAUTION stickers supplied to the instruction manual (basic).
