Pr.63
Pre-set Count Down Value Attained Setting
Parameter #
63
Parameter Name
Pre-set count down value attained
Factory Setting
d0001
Parameter value
d0001 - d9999
When the VFD-A internal counter, triggered by the external input TRG, counts down
and reaches this specified value, the specified output terminal (MO1) will be closed
(assuming that Pr.45 is set to d0003). The output terminal (MO1) will be opened
when the internal counter reaches the value specified in Pr.66. (See chart below)

Parameter value
d0001 - d9999
This parameter determines the value of the VFD-A internal counter. The internal
counter may be triggered by an external signal via the external input TRG terminal.
Upon completion of the countdown, the specified output terminal (MO2) will be
closed (assuming that Pr.46 is set to d0003). (See chart below)
The timing chart is illustrated as follows:
Application example:
"CLOSED"
Pr.45 = d0003
Pr.46 = d0003
Pr.63 = d0005
Pr.66 = d0010
