This protective function is activated by an inverter reset if writing data fails due to power-OFF or a data fault occurs in the storage device during parameter operations.

1. Check if the power was turned OFF during parameter operations.
2. Check the power supply or the devices on the power system to check that the devices have no fault.
3. When E.PE6 occurs due to power-OFF during parameter operations: Check the read value of Pr.890. When the value is "7" or smaller, perform All parameter clear and then an inverter reset. The parameters that had been changed before All parameter clear must be set again.
