5.4 EEPROM-RAM address exchange description
When communication address in the function code table is the way of writing RAM ways, RAM memory
address is the address for power-off but not saving. Under communication way, for writing the command “06H”, if
the parameters shall be saved in power-off condition, it could be realized by only changing value in EEPROM. This
means you shall change “0”, the highest position in RAM address, into “F”, which is to change into the way of
writing EEPROM, also means to change “0XXX” into “FXXX” . Writing life span of EEPROM is generally 1
million times. Frequent changing EEPROM writing will reduce the life span.
Address change example:
Function code
Parameter Name
The RAM Address
The EEPROM Address
F0.10
Maximum frequency
000A
F00A
F0.18
Acceleration time 1
0012
F012
Table 5-4-1 Communication address change rule
Communication address of writing RAM of other parameters shall be in the similar way…
