Parameters Description Range of values Default
Gate function
n Cancel count: The count starts
when the gate opens and
resumes at the load value when
the gate opens again.
n Stop count: The count is inter-
rupted when the gate closes and
resumed at the last actual value
when the gate opens again.
n Abort the
count opera-
tion
n Interrupt the
count opera-
tion
Cancel count
Comparison value The count value is compared with the
comparison value. see also the
parameter "Characteristics of the
output":
n No main direction of count
n Up-count as default
n Down-count as default

Hysteresis A hysteresis is used to eliminate fre-
quent output jitter if the count value
lies within the range of the compar-
ison value.
0 and 1 means: Hysteresis switched
off
0 to 255 0
max. frequency:
counting signals/
hardware gate
You can set the maximum frequency
of the track A/pulse, track B/direction
and hardware gate signals in fixed
steps.
60, 30, 10, 5, 2,
1kHz
60kHz
max. frequency:
Latch
You can set the maximum frequency
of the latch signal in fixed steps.
60, 30, 10, 5, 2,
1kHz
10kHz
Signal evaluation The count and direction signals are
connected to the input.
A rotary transducer is connected to
the input (single, dual or quadruple
evaluation).

Pulse/Direction
Hardware gate In the activated state the Gate control
is made via SWgate and HW-gate,
otherwise via SW-gate only.

In the activated state the "direction"
input signal is inverted.

Characteristics of
the output
The output and the "Comparator"
(STS_CMP) status bit are set,
dependent on this parameter.

ison
n Count ³ com-

n Count £ com-
parison value
n Pulse at com-
parison value
No comparison
