Frequently-used parameters (simple mode parameters)

Parameters that are frequently used for the FR-A800 series are grouped as simple mode parameters.
When Pr. 160 "User group read selection" = "9999", only the simple mode parameters are displayed.
This section explains about frequently-used parameters.
4.4.1 Simple mode parameter list
For simple variable-speed operation of the inverter, the initial values of the parameters may be used
as they are. Set the necessary parameters to meet the load and operational specifications. Parameter
setting, change and check can be performed from the operation panel (FR-DU08).
NOTE Pr. 160 "User group read selection" can narrow down the displayed parameters to only the simple
mode parameters. (In the initial setting, all parameters are displayed.) Set Pr. 160 "User group read
selection" as required. (For the parameter change, refer to page 4-6.)
