If a Multi-function output terminal is set to function as Desired Frequency Attained
(Pr.3-03=d9), then the output will be activated when the programmed frequency is
attained.

The parameter determines the value of the internal counter. The internal counter can be
triggered by the external terminal (Pr.4-4 to Pr.4-6, d18). Upon completion of counting,
the specified output terminal will be activated. (Pr.3-03=d14).

When the counter value is counted up from “1” to the setting value of this parameter, the
corresponding multi-function output terminal will be closed, when sets d15 as desired
value attained setting. 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.
