4.4 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).
POINTPOINT
• 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 101.)

0 to 30%
Set this parameter to obtain a higher starting
torque under V/F control. Also set this when a
loaded motor cannot be driven and the
warning [OL] occurs, then the inverter trips with
[OC1].
