Parameter Display and Parameter Set for Frequency Counter
In the parameter display of a counter relay you change the mode, the
setpoint and the enable of the parameter display.
Value Range
The counter relay counts between 4 and 1000 (Hz).
Parameter display in Run mode:
Retention
Setting retention on the frequency counter serves no purpose since
the frequency is continuously measured.
IMPORTANT
The frequency counter can also be enabled
specifically for a special operating state. This has the
advantage that the cycle time of the device is only
burdened with the frequency measurement when it
is taking place. If the frequency counter is not
enabled, the cycle time of the device is shorter.
