Parameter changes are made to RAM and not to EEPROMResolution:
Adjustments made over the network are stored to the operating memory (RAM) in the drive so it will be lost after a power cycle.
To have the settings stored to the EEPROM the customer must set Bit 1 of the CMI (Extended control word; address 8504) to 1.
This bit will reset to 0 after a save had been completed.
NOTE: The EEPROM has a limit to the number of times it can be written. This is 1,000,000 writes for the ATV312. ATV12, ATV61 and ATV71 are limited to 100,000 writes
