Specifications and Supplemental Information

If block transfers are programmed to continuously write data to the
drive, the EEPROM will quickly exceed its life cycle and
malfunction. The 1336 PLUS does not use RAM to temporarily store
parameter data, but rather stores the data immediately to the
EEPROM. Since the EEPROM has a defined number of “write”
cycles available, frequent block transfers should not be programmed.
