= 0, 1, or 2 – V/f control).
The time and the activation
level of the overload
protection will be affected
as well
13 - If needed, change the

5.2.3 Setting Basic Application Parameters

After running the Oriented Start-up routine and properly setting the parameters, the inverter is ready to operate
in the V/f mode.
The inverter has a number of other parameters that allow its adaptation to the most different applications. This
manual presents some basic parameters that shall be set in most cases. There is a group named "Basic Application"
to make this task easier. A summary of the parameters inside this group is listed in
There is also a group of read only parameters that shows the value of the most important inverter variables such
as voltage, current, etc. The main parameters comprised in this group are listed in
For further details, please refer to the CFW-11 programming manual.
