For example: When using the meter with full scale of 5 volts, adjust Pr.3-01 to 50%.
3-02 Desired Frequency Attained
Settings
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
Settings
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
Settings
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.
