Default value Description
1 Set the number of steps of the cam switch. A
step indicates the point in which the Low state is
switched to the High state or the High state is
switched to the Low state. The valid Step No. is
determined according to the set value of
"Number of Step".
 The value set with "Lower Limit" in the counter
timer block is applied.
Change the setting value in the counter timer
block.
Low Set the initial state of output. When "Count
Value" of the counter timer block is less than the
input value of "Step No.0", the output status turns
to the initial state.
The output status of the step No. later than "Step
No.0" inverts to the High state or the Low state
for every step No.
0 Compares the values of step numbers with
"Count Value" in the counter timer block. When
Maximum value in the
"Count Value" is equal to or larger than the input
valid range
value, the previous status is inverted.
