Parameter
It is suitable for an application in which load varies considerably in rotation speed.
In the free V/f set-up, any intended V/f characteristics can be set by setting the voltage and the fre-
quency at 7 points.
Output voltage of an inverter can be adjusted according to applications. For example, when you use
applications on which loads drastically vary in a rotation speed (output frequency), set frequency that
makes the load heavier and adjust the output voltage. In such way, a motor can be controlled with the
output torque according to loads.
