Wiring of a frequency counter
You integrate a frequency counter into your circuit in the form
of a contact and coil. The counter relay has different coils and
contacts.
Figure 102: EZD circuit diagram with frequency counter
Parameter display and parameter set for frequency counter:
In the parameter display of a counter relay you change
setpoint values and/or the preset value and the enable of the
parameter display.
Value range
The function block operates in the integer range from
0 to 5000
1 kHz 1 = 1000
Behavior when value range is exceeded
The value range cannot be exceeded as the maximum
measured value is less than the value range.
Inputs
The function block inputs
>SH
and
>SL
can have the
following operands:
J
To prevent unpredictable switching states, use each coil of
a relay once only in the circuit diagram. Use a counter input
for the CF, CH, CI counters only once.
