5.3.3 Counter inputs
From version 0200 on, the first 4 digital inputs of the XtracontrolEC22 (X3: I1…I4) may alternatively be used as
counter inputs (C1…C4).
Activating this function requires license, which can be obtained subsequently.
The counter inputs C1…C4 have fast filters, the unipolar inputs I5…I16 have hysteresis.
The counter inputs are connected to the signals of the other unipolar inputs. There is no changeover switching.
Available options for the counter inputs:

up-down counter

pulse and direction counter

quadrature decoder
One of the counter inputs may alternatively be used as a capture input. This configuration requires 3 inputs (partially
as CNT input or CAPT input).
The edges for up, down or pulse may be set to falling and/or rising edge.
Direction: high = up; low = down
Examples for counters: up/down; pulse/direction; encoder (A/B)

Pin Designation Pin Designation
C1 Up, pulse, A (CNT0) C3 Up, pulse, A (CNT1)
C2 Down, direction, B (CNT0) C4 Down, direction, B (CNT1)
