Byte Funktion
2 Input frequency C1 track A
3 Input frequency C1 track B
n Input frequency allows you to preset a filter for I1, I4, I5 and I8. With the help of filters
you may e.g. filter signal peaks at a blurred input signal.
Byte Bit 7 ... 0
0 n Bit 2 ... 0: 0 (fix)
n Bit 3: Count direction track B inverted
– 0 = No (not inverted)
– 1 = Yes (inverted)
n Bit 7 ... 4: 0 (fix)
Byte Bit 7 ... 0
0 n Bit 2 ... 0: Signal evaluation
– 000b = Counter de-activated
– 001b = Rotary encoder single (at A and B)
– 010b = Rotary encoder double (at A and B)
– 011b = Rotary encoder quadruple (at A and B)
– 100b = Direction (pulse at A and direction at B)
Bit 7 ... 3: 0 (fix)

n At de-activated counter the further parameter settings are ignored.
The counters of the 050-1BB30 are continuous counter, whose direction may be preset
by the parameterization. The counters serve e.g. for distance measuring with incremental
encoder. The activation res. de-activation of the counter happens via an internal gate (I
gate). The I gate corresponds to the software gate (SW gate). The SW gate is opened
(activated) via your user application by an edge 0-1 of the bit SW_GATE_SET of the con-
trol word in the output area. The software gate is closed (de-activated) by an edge 0-1 of
the bit SW_GATE_RESET. With an edge 0-1 at SW gate the counter is reset to 0. The
following states influence the I gate:
