Totalizing, tracks A and B
adding (A+B)
The operating mode and con-
sequent counting direction are
selected in the programming
mode.
Track A
Track B
Counting Add.
Up/down counting with two
counting signals,
phase-offset by 90
o
. The coun-
ting direction is automatically
identified from the leading/
lagging 90° phase offset. The
internal phase discriminator
performs the necessary eva-
luation. One, two or fourfold
evaluation is possible.

5.3 Output responses (output modes)
Signal output response is determined by the following:
-Programming of the preset value, start count value, output time,
output logic and output function,
-external resetting,
-external counting direction control.
The diagramms below show the output signal responses.
