09 Signal evaluation
counter 1*
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: Reserved
Bit 7: Gate function (internal gate)
• 0= abort (counting process starts again from loading value)
• 1 = interrupt (counting process is continued with counter
content)

0A Set value counter 1 When a set value is given, the counter can be loaded with the set
value. With an edge 0-1 at COUNTERVAL_SET in the control
word, the set value is accepted in the counter.
0x00
0B Final value counter 1 Upper limitation of the counting range 0x00
0C Loading value
counter 1
Lower limitation of the counting range 0x00
0D Hysteresis counter 1 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.
