Description
n None No restriction of the counting range
n Up: Restricts the up-counting range. The counter starts
from 0 or load value, counts in positive direction up to
the declaration end value -1 and then jumps back to
load value at the next positive transducer pulse.
n Down: Restricts the down-counting range. The counter
starts from the declared start value or load value in
negative direction, counts to 1 and then jumps to start
value at the next negative encoder pulse. Function is
disable with count continuously.
Cancel count: The count starts when the gate opens
n
and resumes at the load value when the gate opens
again.
n Stop count: The count is interrupted when the gate
closes and resumed at the last actual counter value
when the gate opens again.

Start value with counting direction backward.
End value with main counting direction forward.

The count value is compared with the comparison value.
See also the parameter "Characteristics of the output":
n No main counting direction
– Range of values: -2)

– Range of values: -2
n Main counting direction backward
– Range of values: 1 to +2
The hysteresis serves the avoidance of many toggle pro-
cesses of the output, if the counter value is in the range of
the comparison value.
