Both the rising and falling edges of "A" signal and "B" signal are counted.

7.1.2 Signal Polarity Setting
7.1.2.1Encoder Input Signal
The polarity of the encoder A,B,C signal indicates the active level of the signal. The active
level of the encoder A, B and C signals has to be set via CoE:
-
"A" signal 0x80n0:01
-
"B" signal 0x80n0:02
-
"C" signal 0x80n0:03
n - represents the channel number (n= 0;1)
By changing the signal polarity of "A" and/or "B" the direction of counting may change.
For example:
-
By changing the signal "B" polarity which indicates the direction for the
pulse/direction counting mode (Figure 27) the counting direction will change.
-
By changing the polarity of signal "A" for the quadrant counting mode (Figure 30)
results in a change of counting direction.
-
Changing the signal polarity for the clockwise/counterclockwise mode will not
change the counting direction
