3.4 Description of parameters
3.4.1 Displaying and hiding extended parameters (Pr. 0)
When Pr. 0 ="9999", only the simple mode parameters can be displayed on the operation panel (FR-DU07-CNV) and
parameter unit (FR-PU07). (For the simple mode parameters, refer to the parameter list on page 73).
In the initial setting (Pr. 0 ="0"), simple mode parameters and extended parameters can be displayed.
3.4.2 Input frequency to converter (Pr. 1, Pr. 2)
Parameter which can be read from the operation panel and parameter unit can be restricted.
Parameter
Number
Name Initial Value Setting Range Description
0 Simple mode selection 0
9999
Only the simple mode parameters can be
displayed.
0
The simple mode and extended
parameters can be displayed
REMARKS
When a plug-in option is connected to the converter, the option parameters can also be read.
When reading the parameters using the communication option, all parameters can be read regardless of the Pr. 0 setting.
Pr. 991 PU contrast adjustment is displayed as simple mode parameter when the parameter unit (FR-PU07) is mounted.
The following parameters indicate that the converter is available for the use when the the power supply frequency is
between 50Hz and 60Hz.
