5.3 Counting modes for the main and totalizing counter
(input modes)
This counter is able to count in either direction. The counting direc-
tion is independent of the adding or subtracting operating mode. The
exception to this is totalizing (A+B).
Up/down counting with
one counting track A and
an external up/down
signal on track B
Track A
Up/Down
Counting
Differential counting,
track A adding, track B
subtracting (A-B)
Any signal duration and
time.
Track A
Track B

consequent counting
direction selected in the
programming mode.

Up/down counting with
two counting signals,
offset by 90 degrees
The counting direction is
automatically identified
from the leading/lagging
90° phase offset. The
internal phase discrimina-
tor performs the neces-
sary evaluation. Twofold
or four-fold evaluation is
possible.

5.4 Output response (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 diagrams below show the output signal response.
