6.36.2Displaying the rotational speed of the motor or the line speed

: Frequency free unit display magnification

: Frequency free unit conversion selection

: Free unit display gradient characteristic

: Free unit display bias

• 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. Using these parameters, the units of the amounts of processing and feedback in PID control can also be changed.

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

		number. Even when the actual speed of the motor changes according to the particular changes in load, the
		output frequency will always be displayed.
