Note
• In the fxed length control mode
,
the direction cannot be identifed and only the length shall be
calculated based on the number of pulses
.
• Only DI5 can be allocated with the function
"
Length count input
".
• An automatic stop system can be implemented if the length reached signal output by the DO is
fed back to the AC drive input terminal with the stop function
.

10 Use of the Counting Function
The count value needs to be collected by the DI terminal that is allocated with function 23
.
When the count value reaches P7
-
08
(
Set count value
),
the DO terminal allocated with
function 10
(
Set count value reached
)
becomes ON
.
Then the counter stops counting
.
When the count value reaches P7
-
09
(
Designated count value
),
the DO terminal allocated
with function 11
(
Designated count value reached
)
becomes ON
.
The counter continues to
count until
"
Set count value
"
is reached
.
