3-02	Desired Frequency Attained		Unit: 0.1
	Settings	d1.0 to d400 Hz	Factory Setting: d1.0

If a multi-function output terminal is set to function as Desired Frequency Attained (Pr.3-05 or 3-06=d9), then the output will be activated when the programmed frequency is attained.

3-03	Terminal Count Value		Unit: 1
	Settings	d0 to d999	Factory Setting: d0

The parameter determines the upper limit value of the internal counter. The internal counter can be triggered by the external terminal (Pr.4-4 to Pr.4-8, d19). Upon completion of counting, the specified output terminal will be activated. (Pr.3-05, Pr.3-06, d14).

3-04	Preliminary Count Value		Unit: 1
	Settings	d0 to d999	Factory Setting: d0

When the counter value is counted up from “1” to the setting value of this parameter, the corresponding multi-function output terminal which set to d15 as Preliminary Counter Value Attained will be closed. The application can be that closing the multi-function output terminal makes the AC drive operate at low speed until stop before the counting value is going to be attained.
