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.

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.
