Parameter List (System Area)
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.
• If current value fields are empty when batch write is selected, below confirmation message appears. Click " " to batch
write the current values.
• With All St. parameter setting, batch writing from and batch reading to all the connected inverters are available. (Refer to page
103)
• When "Enable m
odel check" is checked in Preference window, the inverter set for system setting and the connected inverter
are checked before the parameter batch write.
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 time increments, Pr. 71 Applied motor etc.) with FR
Configurator, setting values of the related parameters may also change.
For example, if the Pr. 21 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", and changing Pr. 21 setting to "1" will automatically
change the setting of Pr. 7 to "0.5s".)
If parameter writing is performed with or which causes a change of related parameters,
or if or is performed, the following dialog is displayed. Please perform update of
parameter display.
•When the Pr. 342 setting is changed from "0" to "1," only the settings of Pr. 77 Parameter write selection, Pr. 122 PU
communication check time interval, and Pr. 336 RS-485 communication check time interval are written into RAM (not written to
EEPROM). To change the Pr. 77, Pr. 122, and Pr. 336 settings, use the operation panel or the parameter unit.
• 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.
