NOTE
 The data stored as the error reset for retry is only that of the fault which occurred the first time.
 When an converter fault 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.)
Stay away from the motor and machine when the converter trips while the retry function is selected. Motor and
machine will start suddenly (after the reset time has elapsed) after a converter trip.
If the retry function has been selected, apply the CAUTION stickers, which are supplied with the Instruction
Manual of the inverter, to easily visible places.
