H : Frequency units selection
• Function
These parameters are used to change the unit displayed on the display panel. % ⇔ A (ampere)/V (volt)
Frequency ⇔ Motor speed or load speed

■An example of setting for displaying the motor or load speed
Set H to or .
The value obtained by multiplying the operation frequency by the value set with H will be displayed, as shown below.
Value displayed = Frequency displayed or
1)Displaying the rotational speed of the motor
To switch from frequency (default: 60Hz) to speed (rotational speed of the 4P motor operated: 1800
H= | H= | 60⋅30.00=1800 |
2)Displaying the speed of the load
To switch from frequency (default: 60Hz) to speed (speed of the conveyer operated:
H=
.
H=
60⋅0.10=6.0
Note: This parameter is designed to display the value obtained by multiplying the output frequency of the inverter by an integer. Even if the rotational speed of the motor fluctuates with load conditions, the output frequency will always be displayed.
* Using H, the following parameters can be converted.
• A display | Display of the monitored current |
• V display | Display of the monitored voltage |
• Free unit | Display of the monitored frequency |
