Input frequency Selection of a filter via an input frequency for inputs 1 (track A), 4 (latch),
5 (track B), 7 (reset), and 8 (HW gate).
• Filters can e.g. be used to filter signal peaks due to impure input signals.

Connection to input "A/pulse" and "B/direction"
Direction Pulse to input "A/pulse" and "B/direction"
Hardware gate
function
Deactivated Counter is solely controlled via the software gate
(SW gate).
Activated Counter is controlled via the software gate (SW gate)
and hardware gate (HW gate).
Gate function Cancel Counting process starts after a restart with the start
value.
Pause Counting process is continued after a restart with
the current count value.
Output switches If the comparison condition is met, output 6 of the counter module is set.
Counting direction • Inverted counting direction
• Non-inverted counting direction
Reset The counter is reset with a rising edge (0-1 edge) at output 7.
Numerator function Continuous counting
Counting only once Extension of the counting function through
specification of the main counting direction. The
counting range must be defined by a start value and
a final value.
Selection of the main counting direction:
• No main counting direction
–The entire counting range is available.
• Counting up
–The counting range has upper limit values. The
counter starts counting from the start value in
positive direction until it reaches the final value
-1 and then jumps to the start value with the
next encoder pulse.
• Counting down
–The counting range has lower limit values. The
counter starts counting from the start value in
negative direction until it reaches the final value
+1 and then jumps to the start value with the
next encoder pulse.
