Parameters
Display of simple mode parameters and extended parameters (Pr. 160)
● When Pr. 160 = "9999", only the simple mode parameters can be displayed on the operation panel
and the parameter unit. (For the simple mode parameters, refer to the parameter list page 5-2.)
● With the initial value (Pr. 160 = "0"), simple mode parameters and extended parameters can be
displayed.
NOTES When a plug-in option is installed on the inverter, the option parameters can also be read.
Every parameter can be read regardless of the Pr. 160 setting when reading parameters via a com-
munication option.
When reading the parameters using the RS-485 terminals, all parameters can be read regardless of
the Pr. 160 setting by setting Pr. 550 "NET mode operation command source selection" and Pr. 551
"PU mode operation command source selection".

9999 (Automatic determination)
(Initial value)
When the LCD operation panel (FR-LU08) or the parameter unit (FR-PU07) is installed, Pr. 15 "Jog
frequency", Pr. 16 "Jog acceleration/deceleration time", C42 (Pr. 934) "PID display bias coefficient",
C43 (Pr. 934) "PID display bias analog value", C44 (Pr. 935) "PID display gain coefficient", C45 (Pr.
935) "PID display gain analog value" and Pr. 991 "PU contrast adjustment" are displayed as simple
mode parameters.
User group function (Pr. 160, Pr. 172 to Pr. 174)
● The user group function is a function for displaying only the parameters required for a setting.
● A maximum of 16 parameters from any of the parameters can be registered in a user group. When
Pr. 160 = "1", reading/writing is enabled only for the parameters registered in user groups.
(Parameters not registered in user groups can no longer be read.)
● To register a parameter in a user group, set the parameter number in Pr. 173.
● To clear a parameter from a user group, set the parameter number in Pr. 174. To batch clear all the
registered parameters, set Pr. 172 = "9999".
