REMARKS
• When "1" is set in Pr. 342 Communication EEPROM write selection, the parameter setting set from FR Configurator is written into
RAM only (cannot be written to EEPROM).
Batch parameter settings can also be set to EEPROM regardless of the Pr. 342 Communication EEPROM write selection setting of
the inverter. Select [O
ptions] in [Tool] menu to display "Option" window. (Refer to page 91) Click , and check
"E
EPROM write" in the preference setting window to write setting values into EEPROM for batch parameter writing.
If batch parameter write is performed while the checkbox is checked, the above display appears. Some parameter settings are
applied after a reset. After the batch writing, reset the inverter of which the parameter settings are written to, or turn OFF the
power once, then turn it ON again.
• When "Enable m
odel check" is checked in Preference window, the following window appears before the All St. parameter write.
Select a behavior of parameter write for when the inverters set for system setting and the connected inverters are different. If
the model check is not necessary, uncheck "Enable m
odel check" in Preference window. (Refer to page 92)
Note
• When changing some specific parameters (Pr. 21 Acceleration/deceleration, Pr. 71 Applied motor etc.) with FR Configurator,
setting value of related parameters may also change.
For example, if Pr. 21 Acceleration/deceleration time increments setting has been changed, the setting value of acceleration/
deceleration time parameters (Pr. 7, Pr. 8 etc.) also change. (When Pr. 21 ="0" and Pr. 7 = "5.0s", changing Pr. 21 setting
to "1" will automatically change the setting of Pr. 7 to "0.5s".)
If parameter writing is performed with All St. parameter write which causes a change of related parameters, please
perform All St. parameter read or batch read from Parameter List.
•When "Pr. 342 Communication EEPROM write selection = 1", the parameter settings from FR Configurator are written into
RAM only (the settings cannot be written into EEPROM). If the Pr. 342 setting is changed from "0" to "1" during batch
writing, only the settings of Pr. 77 Parameter write selection, Pr. 122 PU communication check time interval, Pr. 336 RS-485
communication check time interval are written into RAM (Pr. 77, Pr. 122, Pr. 336 settings cannot be written into EEPROM). In
this case, to change the setting value of Pr. 77, Pr. 122, Pr. 336, set from a parameter unit or the operation panel.
• All St. parameter setting may take longer than batch write/ batch read of Parameter List since FR Configurator
performs reading/writing to the all stations.
• According to the Pr.77 Parameter write selection and Pr.79 Operation mode selection settings, writing to Pr.122 PU
communication check time interval, Pr.336 RS-485 communication check time interval, and Pr.342 Communication EEPROM write
selection may fail during parameter batch write.
