H > 2T
Correct
All input signals will pass the filter
T < H < 2T
Incorrect
Some valid input signals will be not pass the input
filter and therefore are not being detected
H < T
Incorrect
The input signal will be filtered
H = the HIGH width of the input signal
T = the period of the filtering clock

7.1.5 Compare Trigger Pulse Width
The compare trigger function generates an digital output pulse when the encoder
counter reaches the compare position. Position compare operations and its pulse output
trigger is directly executed by hardware and therefore without any time delay. The pulse
width of the output signal can be set via CoE (0x80n0:0B, n= 0;1). Valid value are 1 to
127.

7.2.1 Counter
If the ECAT-2092T is being used for reading the encoder counter only then the following
PDOs have to be selected: 0x16n0 and 0x1An0 (n= 0;1). By using TwinCAT the required
PDO can be selected with one click by selecting the "Counter" from the predefined PDO
assignment drop box.
