z When M4 is ON, C620 counts with OFF
→ON from X000, via OFF or ON status
from X001, decide the count direction. If
X001 is OFF, execute increase count; if
X001 is ON, execute decrease count”.
z When M6 is ON, C622 counts with
OFF→ON from X000, via OFF or
ON status from X002, decide the
count direction. If X003 is OFF,
execute increase count; if X003 is
ON, execute decrease count”.
Pulse + Direction input mode
AB phase
mode
AB phase counter realize increase/decrease count by the judgment of A、B phase.
The output contactor’s (correspond with the current value) action is the same with
the preceding single phase counter.
z When M8 is ON, C630 counts with
the input X000 (B phase), X001(A
phase) via interruption.
z If M9 is ON, execute RST instruction
to reset.
z If the current value exceeds the set
value, then Y002 is ON; If the current
value is smaller than the set value,
then Y002 is OFF
z When M10 is ON, C632 starts to
count. The count input is X002 (B
phase)、X003(A phase).
z Reset via M11.
z If the current value exceeds the set
value, then Y004 activates; If the
current value is smaller than the set
value, then Y004 is OFF
z In the condition of A phase input is OFF→ON, if B phase input is OFF, the counter is
increase count; if B phase input is ON, the counter is decrease count.
