10 Comparator Bit 2 ... 0: output switches (... if condition is met)
0b000 = never
0b001 = count value  comparison value
0b010 = count value  comparison value
0b100 = count value = comparison value
Bit 3: Invert counting direction track B
0 = no (do not invert)
1 = yes (invert)
Bit 6 ... 4: Reset
0b000 = deactivated
0b001 = HIGH level
0b011 = rising edge
0b101 = one-time rising edge
Bit 7: Reserved
0x00
11 Signal evaluation Bit 2 ... 0: Signal evaluation
• 0b000 = counter deactivated (the other parameter data
details for the counter are ignored)
• 0b001 = rotary transducer 1-fold (connection to "A/pulse"
input)
• 0b010 = rotary transducer 2-fold (connection to "A/pulse"
input)
• 0b011 = rotary transducer 4-fold (connection to "A/pulse"
input and "B/direction")
• 0b100 = direction (pulse at "A/pulse" input and direction
at "B/direction" input)
Bit 6 ... 3: Hardware gate (HW gate)
• 0b000 = deactivated (counter starts by setting SW gate)
• 0b001 = activated (HIGH level at gate activates the HW
gate. Counter starts if HW and SW gate are set.)
Bit 7: Gate function (internal gate)
• 0= abort (counting process starts again from loading
value)
• 1 = interrupt (counting process is continued with counter
content)
12 Final value Upper limitation of the counting range 0x00
13 Start value Lower limitation of the counting range 0x00
14 Hysteresis The hysteresis for instance serves to avoid frequent
switching operations of the output and/or triggering of the
alarm when the count value is within the range of the
comparison value. For the hysteresis you can select a range
between 0 and 255. With the settings 0 and 1 the hysteresis
is switched off.
The hysteresis has an effect on the zero crossing,
comparison, overflow/underflow.
0x00
15 Pulse The pulse duration indicates for how long the output is to be
set if the parameterised comparison criterion is reached or
exceeded. The pulse duration can be specified in steps of
2.048 ms between 0 and 522.24 ms. If the pulse duration is =
0, the output is set until the comparison condition is no
longer met.
