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.
