3.7.11 Use of the Counting Function
The count value needs to be collected by the DI terminal that is allocated with function 25.
When the count value reaches PB-08 (Set count value), the DO terminal allocated with function 8
(Set count value reached) becomes ON. Then the counter stops counting.
When the count value reaches PB-09 (Designated count value), the DO terminal allocated with
function 9 (Designated count value reached) becomes ON. The counter continues to count until
"Set count value" is reached.
Note
1.
PB-09 (Designated count value) must not be greater than PB-08 (Set count value).
2.
DI5 must be used when the pulse frequency is high.
3.
The DO terminal that is allocated with function 9 (Designated count value reached) and
the DO terminal that is allocated with function 8 (Set count value reached) must not be
the same.
4.
In the RUN/STOP state of the AC drive, the counter will not stop until "Set count
value" is reached.
5.
The count value is retentive at power failure.
6.
An automatic stop system can be implemented if the signal output by the DO terminal
with the function (Count value reached) is fed back to the DI terminal of the AC drive
with stop function.
