• 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:
Value displayed = Monitor-displayed or parameter-set frequency × H
1) Displaying the motor speed
To switch the display mode from 60Hz (default setting) to 1800min
-1 (the rotating speed of the 4P motor)
H H
2) Displaying the speed of the loading unit
To switch the display mode from 60Hz (default setting) to 6m/min
-1 (the speed of the conveyer)
H H
Note: This parameter displays the inverter output frequency as the value obtained by multiplying it by a
positive number. This does not mean that the actual motor speed or line speed are indicated
with accuracy.
