6.20.3Displaying the rotational speed of the motor or the line speed

H : Frequency free unit magnification

H : Inclination characteristic of free unit display

H : Bias of free unit display

•Function

The frequency or any other item displayed on the monitor can be converted freely into the rotational speed of the motor, the operating speed of the load, and so on.

The value obtained by multiplying the displayed frequency by the H-set value will be displayed as follows:
